These oil filled motors are one among the proven & successful products

from the house of C.R.I. These motors are developed with due diligence

complying with all safety standards and giving importance to the

customers' need. All the components that are in contact with water is

made of AISI 304 stainless steel and the motor is pre-filled with edible

grade oil which acts as coolant as well as lubricant and heat dissipation

media. The freezing point of the oil used is -10 deg C.

High operating efficiency and lesser power consumption

Extremely hard wearing ball & angular contact bearings

Filled with edible grade oil

Can be easily dismantled and repaired

These prime mover submersible motors are suitable to couple with

deepwell submersible pump ends, used for irrigation, domestic water

supply, fountains, industrial water supply, pressure boosting units,

ponds, gardens, sprinkler systems and mining.

Dynamically balanced rotors and equipped with quality ball bearings

maintain uniform clearance thereby giving better efficiency and

increase the life cycle. Up to 3.0 kW 2 and from 3.7 kW 3 ball bearings

are used to withstand the high axial load. The lower ball bearings are

of angular contact type. The shaft extension is made of 300 series

stainless steel to avoid splines worn-out.

High quality carbon/ceramic mechanical seal and oil seal made of

Nitrile rubber are used to ensure better sealing system. For easy

maintenance & safe handling plug-in type removable cable leads are

provided. It is mandatory to use CRI control box for all 1 ph motors and

adequate control & protection system is required for all 3 ph motors.

Mounting dimensions of these motors are in accordance with NEMA

standard.

3 wire removable type EPDM rubber flat cable

These motors are hermetically sealed, encapsulated and water lubricated

type with removable cable lead out. The stator windings are of enameled

copper wire and the wound stator is mounted in a stainless steel shell and

is completely protected by a stainless steel cylinder and stator room is

pre-filled with resin. The resin filled in the space between the stator & the

stainless steel cylinder dissipates heat quickly resulting in longer motor life.

Except stator, other portions of the motor is pre-filled with deionised water

containing propylene glycol (anti-freeze agent) which serves as coolant &

lubricant for rotor, bushes and thrust bearing. If any leakage of water is

observed bring to the notice of the distributor. Dynamically balanced rotors

of these motors maintain uniform clearance thereby giving better

efficiency and increase the life cycle of the water lubricated bush bearings.

Specially designed high performance thrust bearings are used that can

withstand high axial thrust loads and upthrust loads with minimum wear

and tear.

The unique design of thrust bearings creates a wedge of water between

the shoe and the disc and thereby providing better water lubrication and

increases the life cycle of the thrust bearings. Pressure equalizing rubber

diaphragm is provided to guard the pressure and volume variations due to

thermal expansion of the water inside the motor. Motor sealing are made

by means of ‘O’ rings. Shaft seals and sand guard prevents ingress of well

water, sand and fiber particles into the motor. Care should be taken to

ensure that the motor does not run when it is not submerged in the water.

To prevent the motor dry running, install water level monitor / dry run

preventor. The motor needs a constant flow of water past it’s body to keep

it at correct operating temperature. Ideally, the motor should be set just

below the level at which water enters the bore well. When this level is not

ascertained, fit a “flow inducer pipe” over the pumpset to ensure adequate

cooling. It is mandatory to install C.R.I Control box for all single phase 3

wire motors. All 3 Ph motors require an adequate motor protection

control panel. Mounting dimensions of motors are in accordance

with NEMA standards.

Corrosive resistant stainless steel body.

Specially designed thrust bearing to withstand high axial thrust loads.

Copper rotors and low watt loss silicon steel laminations for higher

starting torque.

Higher power factor resulting in lesser power consumption.

Larger shaft diameter for better power transmission.

High heat dissipation for better life cycle.

These motors are eco-friendly wet type, water filled rewindable. The stator windings are of water proof synthetic film

insulated copper winding wires. It features water lubricated thrust and journal bearings. Motor is pre-filled with clear, cold,

pure, fresh, filtered water. However, on request motors can be pre-filled with water and propylene glycol (Anti-freeze

agent) for places where the temperature is below the freezing conditions. Before commissioning, ensure the pre-filled level

of water inside the motor. If any loss of volume is noticed, refill with clear, cold, pure, fresh, filtered water, through water

filling plugs / valves provided in the upper housing. Where the use of anti-freeze agent mixed water is not be allowed for

special applications, these motors can also be filled with clear, cold, pure, fresh, filtered water and operated. Dynamically
