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.

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.

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

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
