Technical Specifications

Thrust Bearing Kit "Mitchell Type"
Heavy duty bearings provide the option to rotate two - way, have the capacity to carry high thrust load.
Mechanical Seal
Prevents entry of sand and other particles into motor. Keeps high durability for bearings.
Membrane
Membrane minimizes the expansion pressure that is caused by heating of cooling waters inside the motor.
Motor Adjustment Screw
Standard shaft height can be precisely adjusted by the adjustment screw on the thrust bearing base.

 

PT100 Overheating Protection
By connecting the PT100 thermal sensors to the slot that is standardly placed on upper bearing body, motor temperature values can be easily measured.
Slinger (Sand Guard)
Slinger helps to prevent the sand inside the water of the well entering in mechanical seal and through mechanical seal to inside of the motor.
Rotor Shaft Bushing
Chrome-plated and precisely machined bearing collets which are located in the radial bearings operating area, have great importance for bearingthe rotor.
Radial Carbon Bearing
Radial carbon bearings, which have channels in its structure that makes it possible to get lubricated by water easily, provides precise bearing of rotor shaft at upand down.
Check Valve
It rules the pressure changes in water excellently check valve balances inner pressure, by throwing out and gettin in after filtering the water, dependently to changing pressure. So it prevents the membrane from pressure explosion.
Bobin Teli
PE2+PA coil wire allows the engine to run at 70°C well temperature. Increases the life and durability of the submersible motor.
Counter-Thrust Sliding Block
Provides safe operation conditions for motor by absorbing Up-Thrust loads with it's machined surface and water channels on it.
Rotor Shaft
Rotor shaft, top side is made of AISI 304 material. Shaft end connection in NEMA Standards.
