1.2 DESCRIPTION
The PHL Pump is an electro-mechanical metering pump, oil-lubricated with a sealed housing, allowing adjustment of its capacity when stopped or in operation. It is designed for industrial operation in continuous mode. It is made up of the following items:
• a driving device consisting of a motor,
• a drive end assembly,
• a liquid end assembly.
1.3 OPERATING PRINCIPLE OF THE DRIVE END ASSEMBLY ( Figure-1)
The movement of rotation of the motor is transmitted by the worm shaft [17] to the tangent Worm wheel [18]. The system of connecting rod and eccentric transforms the rotary movement into a linear movement. The piston connected to the connecting rod [20] move with an adjusting linear stroke. The stroke of the piston depends to the position of the sliding crank [22] and the eccentric female [22A].

1.4 OPERATING PRINCIPLE OF THE LIQUID END ASSEMBLY
During the suction phase, the displacement of the piston creates a partial vacuum in the displacement chamber. The diaphragm is hydraulically coupled to the piston and will suck a set volume (capacity) of fluid through the suction valve assembly and into the head. The discharge valve assembly seals off the discharge circuit. The process is then inverted and the return phase begins. The piston compresses the hydraulic oil in the displacement chamber. The oil then exerts pressure on the diaphragm, thus forcing the liquid through the discharge valve assembly. The suction valve assembly seals off the suction circuit.
1.5 SAFETY & HEALTH INSTRUCTIONS The personnel responsible for installing, operating and maintaining this equipment must become acquainted with, assimilate and comply with the contents of this manual in order to:
• Avoid any possible risk to themselves or to third parties, • Ensure the reliability of the equipment, • Avoid any error or pollution due to incorrect operation.
Any servicing on this equipment must be carried out when it is stopped. Any accidental start-up must be prevented (either by locking the switch or removing the fuse on the power supply line). A notice must be attached to the location of the switch to warn that servicing is being carried out on the equipment.
During oil changing operations, the waste oil must be collected in a suitable receptacle. Any overflow of oil, which may result must be removed using a degreasing agent suitable for the operating conditions.
Soiled cleaning cloths must be stored in suitable receptacles. The oil, degreasing agent and cleaning cloths must be stored in accordance with the rules on pollution. Switch off the power supply as soon as any fault is detected during operation: abnormal heating or unusual noise. Special care has to be taken for chemicals used in the process (acids, bases, oxidizing / reducing solutions...).

CHAPTER – 3
START UP
3.1 PROCEDURE BEFORE START UP
Special care to be taken for chemicals used in process (acids, bases, oxidizing / reducing solutions...).
• Check the pump fixation (Chapter 2.4). • Fill the housing with the lubricating oil (Chapter 4.2) • Check the opening of all isolating valves installed on the suction and discharge circuits.
Disconnect discharge circuit (caution to the liquid pumped). This procedure is to verify that there is liquid present (pump is installed in flooded suction), or to prime the pump (pump installed in suction lift).
• Check that the pump capacity is set to "0%" (Stroke-knob).
3.2 START UP
• Once all the checks and procedures described in the previous section have been Carried out, start up the pump. • Check visually and by listening, in particular, check that there are no suspicious Noises. • Make sure that the Stroke-knob is unlocked. • Proceed to the degassing (Chapter 7 - Servicing the liquid end). • Adjust the pump capacity gradually from 0 % to 100% and control the liquid output at Priming valve. • As soon as the liquid to be pumped flows out of the priming valve, priming on the Process side has been achieved. Close the priming valve or reconnect the discharge Pipe, as applicable. • Once the priming is obtained, adjust the pump to the desired capacity. • Lock the Stroke-knob with the locking screw.
3.3 FAILURES ON START UP / TRACING CAUSES OF FAILUR E
The motor runs with difficulty / heats up / Noisy
• One phase is incorrectly connected. • The characteristics of the electrical power supply do not match the specifications of the motor. • The electrical connection used is not suitable. • The Housing does not contain any oil. Fill up with oil (See Chapter 3.4). • The Motor coupling/bearings can be worn, replace them if necessary
The pump produces no flow
• The pump capacity is adjusted to « 0 % “: Adjust the capacity to the desired Value and lock the Stroke-knob.
• Check the leak-tightness of the piping Relief valve. • The liquid end is not primed: release the pressure on the discharge pipe and prime the liquid end, or
check the leak-tightness of the suction circuit. • The balls of the valve assemblies are blocked by particles: clean or replace the valve assemblies. • First, check whether the presences of the particles in the valve assemblies are normal and take
corrective action if necessary. • If the problem is not solved check the mechanical assembly and liquid end functioning.
PHL Series Pump
MILTONROY INDIA PVT LTD
11
The flow rate is lower than desired
• The pump capacity is incorrectly adjusted: adjust the capacity to the desired Value and lock the Stroke-knob. • The suction power is insufficient (pipe cross-section too small or pipe too long): replace the pipe
with ones that have a larger cross-section or install the Pump in flooded suction. • The leak-tightness of suction pipe is unsatisfactory. • The viscosity of the liquid is incompatible with the pump's capabilities.
The capacity is greater than desired
• The stroke adjustment of the pump is incorrect. • A siphoning phenomenon is observed: check if the suction pressure is not superior to the discharge
pressure. So necessary, to place a back-pressure valve on the discharge line.
The capacity is variable
• This problem may be due to particles from the piping which interferes with the operation of the valve assemblies: clean the piping and the valve assemblies (by checking the assembly sequence of different components).
3.4 SCHEDULE FOR CHECKS & MAINTENANCE OPERATION
• The Programme of checks and maintenance operations depends on the conditions in which the equipment is used. For this reason, the following frequencies are given as an example only. Individual users should adapt these frequencies to their own specific operating conditions.

4.3 OTHER MAINTENANCE OF OPERATIONS
CHECKING THE PUMP CAPACITY
This is to determine the straight line representing the pump's capacity according to its adjustment. Four measurements are sufficient (adjustment at 100%, 75%, 50% and 25%). There are two possible methods:
If the pump is installed in flooded suction mode
Measure the volume of pumped liquid from a calibrating chamber for a given period of time. It may be necessary to reproduce actual operating conditions (suction pressure).
If the pump is installed in suction Lift or Negativ e suction mode
Measure the volume of discharged liquid. It may be necessary to reduce actual operating conditions (discharge pressure).
The Flooded suction method is recommended as this method avoids placing the operator in contact with the liquid, which is important if the pumped liquid is hazardous.
For a precise check, it may be necessary to use an electromagnetic flow meter.
4.4 ORDERING THE PARTS
To make it easier to register your order for spare parts and ensure a quick delivery, please provide us the following details:
• Information on the pump: Model and Serial number. These two items of information are shown on the Nameplate mounted on the pump.
