AXIAL BEARING SET
Appropriate for heavy working conditions, axial bearing set having stainless segments, having antimonial carbon bearing is used.

HIGH QUALITY CARBON BEARINGS
Having helical channels, which facilitating water lubricating, radial carbon bushings, rotor shaft bearings.

ADJUSTING SCREW
It detects the standard shaft height under the axial bearing body made of stainless material.

ROTOR
Dynamically balanced with high precision (max. 0,5 g), stainless steel rotor shaft, having conductors of electrolytic copper.

SHAFT BUSHING
It is used for extra endurance in parts remaining in the radial bearing over the rotor.

MECHANICAL SEAL FOR TIGHTNESS
Mechanical seal made of viton material, having stainless AISI304-316 quality spring and SiC-SiC elements provides extra protection against sand.

UP-TRANS RING
Up-trans ring mode of bronze moferiol for enobling the motor work sofely by restricting the rotor stort.

ENERGY CABLE OUTLET
With rubber and metol parts, it enables the connection of the energy cable coming from the inside of the motor to the frame and its tightness.

PT100 TEMPERATURE SENSOR
In order to keep the internal motor temperature under control PT100 element can be easily applied in production or later.

MEMBRANE
It endures the expansion pressure generated by the heating of the water within the motor.

SAND ROASTING TYRE
It prevents the sand and particles In the water from reaching Into the motor by turning with rotor shaft.

WATER FILLING AND RELEASING CHECK VALVE
Check valve mode of stainless material, which allows entrance and exit of water in cose of a lacking of water arising from the pressure change and heating, prevents motor failures generated from a puncture in the membrane.
