MHC8B (55-110kW)
MOTOR
4-pole induction continuous rated motor with squirrel cage rotor. Bi-metallic switches (thermals) embedded in stator winding to protect against overheating. Stator insulation class ‘H’ (180ºC)
POWER SUPPLY
3 phase, 50 Hz, AC Supply, 400V. Other voltages available upon request.
BALL BEARINGS
The rotor shaft is carried on a double row angular contact ball bearing which carries the high thrust and radial loads. The Upper bearing on units up to 40HP is a deep groove ball bearing; on 50HP and above it is fitted with a roller bearing. The bearings are enclosed with high temperature grease containing special Anti-corrosion additive.
POWER CABLE
Waterproof/oil proof, rubber-insulated, neoprene-sheathed copper conductor flexible cable, 25ft. (7.6m) length standard. Type SOOW in North America, EPR in the Middle East and HO7RN in the EU. Optional Trailing cable for thermals and seal probe sensor.
SHAFT SEALS
Double Mechanical Seals, outer and inner are Silicon Carbide, both rotating and stationary faces. Equipped with Moisture Sensor to detect progressive seal wear.
