Product Introduction

Applications

Conditions

WQ series submersible sewage pump, adopts the advantages of dometics and foreign products with comprehensive improvements

in hydraulic mould, mechnical structure, sealing, cooling, protection, control and etc. Our energy-saving products are effective in the

solid wastes and keeping the long fiber from winding with high efficiency and high reliability. With the special control panel, not only

the automatic control is achieved, but also the safety of motor is secured.

WQ series submersible sewage pump is mainly used in municipal engineering projects, buildings,industrial waste release and waste

water treatment, which can pump dirty water, waste water, rain water with solid and long fiber wastes.

1.Medium temperature

1.With special single or double flow channel impeller and wide pump body, it is most suitable for pumping the water for both with solid

and fiber wastes.

2.Tow separated single face mechnical seals are installed in serial inside, which helps to facilitate uneasy leakage and oil lubricated

compared with external style. Special spiral groove and fissure is designed to prevent solid deposits on the mechanical seal and keep the

pump operate stably. Special setting way of mechanical seal is combined with the bearings, making the shaft shorter mechanical seal is

combined with the bearing, making the shaft shorter arm, strong rigidity, less jumping, reducing the leakage of mechanical seal and elongating its life.

3. Motor with protection grade Ipx8 can work under water, making it best and most effective in cooling, F class insulation makes winding

work in higher temperature. It is more endurable than the common motors.

4. Consummate mixture of special electric control panel, liquid float ball switch and pump protection devices can automatically monitor4

and alarm for water leakage and overheat of winding, with power-off protection for short circuit, overload, lack of phase, voltage off and

accurate automation control for pump start, stop, alternation and submerging depth. It is no need to do the work manually. Auto-coupled

voltage reduced start and electronic soft start can be selected. All these can make you operate the pump safely, reliable and trouble-freely.

5. Motor and hydraulic parts share the common shaft without checking the rotating shaft, which makes it easy for dismantle, assemble

and maintenance on site, and can also reduce the time duration of the pump stop, making maintenance expenses more economical.

Compact structure makes it smaller, special crane handle makes it easy to hoist.

6. Five modes of installation: auto-coupled installation, hard-pipe movable installation, soft-pipe movable installation, fixed base-plate

installation and fixed dry installation can be selected flexible.

In auto-coupled installation, pump and discharge pipe are connected by discharge pipe head in between. Regular fasten parts are unnecessarily used.

Just simply move the pump along the guide rod up and down when connecting and disconnecting between them. It is very convenient, trouble free.

Submersible sewage pump of fixed dry installation can not only replace the old vertical sewage pump, but van also confront with the flood.

Thus, no extra fold control works are needed. That will contribute to reducing the construction cost.

Hard pipe movable installation, soft-pipe movable installation and fixed base-plate installation are all convenient installations.

7. The pump can be equipped with motor cooling system, which can not only cool the motor sufficiently, but also help lower liquid level of

the sewage tank so as to pump sewage liquid as maximum as possible.

8. There exists no basic problem of noise because the pump works under water, contributing to the environmental protection.

Structure Instructions

Pump Body Impeller

Pump body and impeller are well matched by the repeated modifications and designs with AutoACD technology. The passage way is

wider and the circulating ability for the sewage is best. The impeller is strictly balanced so as to reduce vibration to the minimum degree and

Motor

Specially designed submersible motor is in protection grade of IPX8 and insulation grade F for stator winding. The working temperature

limit of the insulation material is 155C. The over-heat protection device inside protects the motor through control panel.

Cooling of moto

Mechanical Seal

Oil House

Bearing

Upper bearing is ball bearing, which bears radial force while lower bearing bears radial and axial force. In accordance with different radial

and axial force, double line ball bearings, single line ball bearing and one ball bearing plus one column roller bearing are of option with enough

Motor cooling system can be installed to cool the motor for those pumps exceeding 11kW. Cooling liquid flows between

stator shell and cooling sleeve. Cooling liquid can be either transferred by pump or connected with cold water outside. The

cooling channels are different because of these two kinds of methods. So, if the cooling system is needed, it must be

indicated what kind of method you want when you order. If the liquid is transferred by the pump, its structure may prevent

large-size solids from entering the cooling passage, and sediments inside the sleeve can be made after long period of time

of operation, but the sediments can be washed off by the washing liquid from the cooling sleeve with external matched

washer. Motor cooling system can lower the lowest water level and remove waste water in the tank to the greatest degree

possible.

Motors of over 11kW can also be equipped without motor cooling system and be cooled directly by pumped liquid instead

but liquid level will be higher than with motor cooling system.

Motors of 7.5kW less is cooled by liquid pumped through heat release board of the stator cover and liquid shall cover the stator as complete

as possible and at least half of it.

Mechanical seal of Shanghai Burgemann is adopted with low friction parameter of endurable material, rubber parts are oil tolerable,

and metal parts are of stainless steel, which can ensure trouble free operation more than 8000 hours.

Oil in the house can not only lubricate the mechanical seal but also carry away the bearing heat and avoid liquid leakage. Leakage

probe

inside can issue warning and stop the pump through control panel to remind operator of changing oil or repairing the mechanical seal

once the density of water to oil house leak through mechanical seal to a certain extent.

Oil-adding hole structure can increase oil adding speed and ensure that there is a certain amount of air inside the oil house and curb

pressure up inside to avoid excessive wear or leakage when oil temperature is rising up.



allowance. In addition, these bearings are of famous brands to ensure the endurable ability

Cable and Seal

Cable applied is soft and sewage water tolerable with excellent mechanical strength and oil resistant ability. Cross section of cable

and capacity is selected in condition of 400C (regularly 250C) and long time continuous working. So it is safe and long life in usual

condition.

Cable gland extrudes the cable seal ring to seal the cable and wiring box reliably. Cable should be fixed to avoid to be pulled off. The

cable marked with color and number makes it easier to differentiate and connect. There are signs of ground wire and fastening bolts

for ground wire inside the wiring box of motor and control panel. It is safe and reliable for ground wire connecting.

“O” ring, cable seal and mechanical seal for every pump should be strictly inspected for seal test to ensure reliable sealing of motor

and wiring box while being installed.

Protection Device

Pump of 7.5kW and less is equipped with overheating protection device for motor winding and water leakage probe. Pump of 11kW and

above is equipped with overheating protection device for motor winding, floating ball switch and leakage probe. Pump of 30kW and

above is installed with one additional water leakage probe inside motor cover. It works when the protection devices are connected with

the electric control panel specially designed for the submersible sewage pump. Although our control panel for the submersible sewage

pump is optional for you, in order to ensure safe and reliable operation of your pump, especially to avoid the burning of motor, selecting

our special control panel is your wise choice. Please be sure to check with our engineers concerning technical issues of electronics,

especially for the protection device if the users apply there own control panel.

Instructions for each protection device

The Overheat Protector

The overheat protector is the electrical appliance controlled by temperature, installed inside the stator winding of motor. Under usual

operating conditions, when temperature of winding reaches the set point of the overheat protector, the overheat protector makes

“overheating” pilot lamp flash through control panel and stop the motor automatically. This reminds the operator for checking the

problem.

After the temperature drops, the motor will resume the start state.



Water Leakage Probe

Water leakage probe is used for water leakage test. The lead wire of the two cathodes

on the probe is connected to the control panel through the cable. When the water leaks

to the oil house through mechanical seal from motor side to certain extend, the two

cathodes on the probe will be conducted at once and send out alarming signal (the

pilot light is on) to control panel. The motor power is kept cutting off to prevent short

circuit by control panel. At the dame time operator is informed to inspect the

mechanical seal or replace the oil in the oil house in time.

The Float Switch

The float switch is used to test that if the mechanical seal on the motor side is useless or not

and if there is any water entering into the motor cavity. The float switch is located under the

motor cavity and in the cavity beside the bearing. The hole in the cavity leads to bearing

chamber. When the mechanical seal on the motor side is broken, as a result of that the oil or

water in the oil house enters the cavity through bearing chamber, or the water in motor

chamber enters the cavity, the float ball will rise, It will send our alarming signal (the pilot light

is on) and stop the pump automatically reminding the operator for repairing the pump.

Hoisting Device

The handle of pump is reasonable designed, which make hoisting convenient and safe.

Auto-coupled installation is actually to connect the pump and pipe. Auto-coupled device makes the pump and discharge pipe

separate without any need of regular fasten parts, so it is very easy to connect and disconnect the pump and discharge pipe.

Auto-coupled installation device only consists of discharge head, connecting rod, rod bracket and coupled bracket. Connecting

rod serves as guidance only and the water pipe or steel pipe can serve the purpose and be cut to fit the depth of the tank as

required. During the process of installation, when discharge head, connecting rod and rod bracket re ready, place auto-coupled

bracket on the pump body and hoist the pump, put the semicircle into the connecting rod, slip the pump down the connecting rod

to the bottom, auto-coupled bracket can hold the pump body and discharge head tight, and pump discharge and suction pipe are

fit, and flange end can fit well then. When repairing the pump, pump and discharge head will be disconnected when pump is

hoisted.

Because auto installation device and pump are comparatively separate, original auto-coupled device can still be used if you

need to change the pump of the same diameter but higher or lower lift.

Performance curve & notes to main data

Bold parts in curve on Performance Curve Chart-1 show the recommended application scope of pump. Pump efficiency will be very low or

the motor will face the danger of overloading when the scope is exceeded. The shaft power of such pumps as showed on the chart will

rise up sharply as flow capacity increases. If flow capacity exceeds the limit on the right, shaft power will exceed the rated motor power.

Motor can not work for a long period of time when the medium temperature is too high or the motor has not been cooled enough.

For all submersible sewage pumps, shaft power will be far lower than the rated motor power if flow is below the limit on the left. The

efficiency of the unit is very low and it is not economical to have pumps work under such conditions.

The diameter of pumped solid stuff in the media should not be greater than the minimum size of flow channel. It is recommended that the

diameter of solid stuff shall be under 80% of the minimum size of flow channel. Take WQ2368-604 as shown above for an example,

diameter of solid stuff should not exceed 90mm.

The pump weight does not include such spare parts in various kinds of installations as auto-coupled set, suction bent joint pipe, base

plate, the connector of bent pipe and soft pipe, etc.

Shaft power of pump similar to WQ2175-415 as shown on Performance Curve Chart-2 will not increase anymore when the power is

increased to a certain extent. These pumps have no danger of overloading. The effect of overload is quite limited if it does a little by

chance. Therefore, the motor is safe when the pump is operating under the condition of any kind of flow. However, it is more economical

and efficient to make the pump operates in the recommended range.

These are the drawings and instructions for the auto-coupling installation and movable installation. (Take WQ2175-207 for an example.)

1.All the rod brackets can be fixed by expansion bolts M16x150 which can be ordered directly from our company. Function of rubber block

on the rod bracket: fasten the adjusting bolt on rubber block thus make the rubber block tighten the internal hole of rod bracket and make it

stable.

2.The length of connecting rod should be calculated according to the marked well depth. Please refer to the attached sheet 1 for the details

of connecting rod.

3.For all pumps of auto-coupled installation, the well bottom should be made flat, and height of discharge pipe may keep the height from

suction to well bottom enough to make pump have good suction conditions. Therefore, it’s no need to make additional convex part for the

discharge pipe in order to save the construction trouble.

4. indicates the lowest water level when the pump has no motor cooling system. Water level should be higher than the lowest water level

and immerse the pump as completely as possible to make the motor get cooled enough. The lowest water level can be controlled by the

float switch. The special control panels for sewage pumps supplied by our company are all water level controlling modes with certain float

switches.

Special control panel for submersible sewage pump

Float switch theory drawings

For water supply For water discharge

Special control panel for submersible sewage pump float switchternimal box and wiring pipe

Inside the submersible sewage pump, there are various kinds of protection devices for motor. The control panel should be

matched in accordance with these devices. Besides, the control panel should also be made with float switch for controlling

the liquid level. So, control panel for sewage pump should be specially designed and used professionally. The control panel

supplied by our company is a good example of this kind, which, in addition, has multiple protection functions of master

return circuit short-circuit, overloading and lack of phase. For those of over 15kW, there are also functions of auto-coupled

voltage reducing and electric soft start modes. When control panel with master and stand-by controls works under normal

conditions, the master and stand-by control pump will alternate in the following ways: by hand, (under the condition of

endless operation) and timely automation (under the condition of intermittent operation). In case of trouble, control panel

with both master and slave control can switch off the troubled pump and turn on the backup one automatically. If customers

use our control panel but disconnect with the pump protection device or they use their own control panel not well matched

with the pump protection devices and with no functions of main return circuit short-circuit, overloading and lack of phase

and even not equipped with fuse, the control panel will not alarm and will not stop the pump when in trouble. The result is

that the motor will be burned if they do not conduct normal check. Therefore, it is better that the users buy the special

control panel for sewage pump when they order the sewage pumps

Above is a brief introduction of the special control panel for sewage pumps only. Please refer to our catalogue or

brochure for details.

The lowest liquid level is marked on the catalogue and instruction for the submersible sewage pump. For pumps of

7.5kW and lower ones, there is a marking of lowest liquid level point, where the stator of motor is submerged in half.

But for the pump of 11kW and greater ones, there are two lowest liquid level points for both with motor cooling system

and without motor cooling system. The lowest liquid level for those without motor cooling system can guarantee motor

cooling. The lowest liquid level for those with motor cooling system, however, can exhaust the air inside pump before

operation and make the suction point submerge to the minimum extent, thus no air will be absorbed during operation.

The float ball switch for liquid level is used when the control panel is set in auto mode.The connection and setting:

there are three wires of black, brown and blue inside the cable of float ball switch. When the float ball is up, the wires

of black and brown are connected while the ones of black and blue are disconnected.


When the float ball is down, the wires of black and blue are connected while the ones of black and brown are disconnected.

The switch is placed in standby position when the float ball is in the middle. It operates in turn when the float ball is up or

down. Connect the black and brown wire with control panel and wrap the blue one for insulation when de-watering. Connect

the black and blue wire with control panel and wrap the brown one for insulation when supplying water. If only one float ball

switch controls two liquid levels for start and shutoff of pump, the position for gravity hammer can be adjusted thus the liquid

difference for start and shutoff of pump is determined. In theory, one float ball switch can control the water level of one set

pumps during operation of start and shutoff pump. The arm length of float ball will become longer accordingly when the water

level difference is increasing and accuracy of liquid level control will be effected negatively by the deed weight of the cable

from gravity hammer to float ball. Float ball setting of control panel for sewage pump from our company: for the main pump,

there are two float ball switches to control the start and shutoff separately. For the standby pump added for high water level,

only one float ball switch controls the start and shutoff. Customers are welcome to place an order for our float ball switch if

they need more float ball switches than ordinary or even if they do not need our control panel for sewage pump.

Special Instructions for WQ4000

Main Applications

Features and Main Advantages

There are some difference between WQ2000 and WQ4000 type pumps, so we instruct WQ4000 type pumps at bellow.

WQ4000 type pumps are mainly used in municipal engineering projects, buildings, industrial waste release, waste

water treatment, city’s water supply, water circulating for power plant and farmland flood-drain and irrigation. Which

can pump clean water, dirty water, rain water with solid and long fiber wastes. But it can not use for pump erosed and

erodent medium.

1.WQ4000 type submersible sewage pumps adopted the advantages of domestic and foreign mix flow type pump with

comprehensive improvements in hydraulic model. The impeller is vane, efficiency is high, The pumps are widely used

in large flow and middle or low head conditions.

2.Four modes of installation: auto-coupled installation, hard-pipe movable installation, soft-pipe movable installation

and fixed base-plate installation.

3.The largest dimension of the solid which can across the impeller is marked in the “Main data” of WQ4000 type

pumps.

Mix flow impeller, impeller are compose of blade, widely used in large flow, middle and low head conditions.

All of the WQ4000 type pump equipped entrance pipe.

Upper bearing is ball bearing, which bears radial force while lower bearing bears radial and axial force. In

accordance with different radial and axial force, double-line ball bearings, single-line ball bearing and two ball

bearings plus one column roller bearing are option with enough allowance. In addition, these bearings are of famous

brands to ensure the endurable ability.

There are five installation modes: auto-coupled installation (Z), the first fixed base-plate installation (P), the second

fixed base-plate installation (F), soft-pipe movable installation (R), hard-pipe movable installation (Y).

Installation mode is according to the discharge nozzle diameter.

In installation drawings, the flange which discharge nozzle diameter no more than 300 according to GB/T

17241.6-1998 0.6Mpa standard, the flange which discharge nozzle diameter exceeding 300 according to GB/T

17241.6-1998 1.0Mpa standard.

All of the installation of pumps are very simply.

Only can be applicable to the pump discharge nozzle diameter is 150.

Only can be applicable to the pump discharge nozzle diameter is 150 to 600. All the pump that use auto-coupled

installation must ensure the distance from suction to the grand is adequacy, the distance usually is the pump discharge

nozzle diameter, so as to the pump can suction well. Except pump discharge nozzle diameter is 150, all of the pump must

build a stage for discharge bent pipe. For example WQ4520-859:

Only can be applicable to the pump which discharge nozzle diameter is 250 and 900. Because we must ensure the distance of

suction to the grand is enough, so we must build two concrete stages, then put the pump between the two stages, two stages

support the pump.

For example WQ4520-665:

Fixed the pump on the foundation, connected the discharge pipe, then the pump can operate. The base-plate must be

fixed by grounding bolts. The material of grounding bolts is stainless steel. Other instructions are similar to the WQ

instruction.

Bold parts in curve on performance curve chart show the recommended application scope of pump. Pump

efficiency will be very low or the motor will face the danger of overloading when the scope is exceeded.

Because WQ4000 type pumps are mix flow pump, the draft power of the pumps will reduce when the flow

increase. If the flow is less the left scope, the motor will overloading; if the flow is large than the right scope,

motor will not overloading, but the pump’s efficiency is very low, it is unreasonable to use pump at this condition,

and the pump will bring some problem such as libration and noise.
