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), 1.15 Service Factor.
POWER SUPPLY
3 phase, 60 Hz, AC Supply, 208, 230,460,575. 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, 50ft. (15m) length standard. Type SOOW in North America, EPR in the Middle
East and HO7RN in the EU with 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.
HYDRAULICS
Two Vane Semi-Open Impellers, Hydrodynamically balanced with improved flow pat-
tern contribute to a virtually clog-free pump.
COOLING
Motor casing with large surface area ensure efficient heat dissipation and low
temperature rise. Shrink fitted stators and short shaft overhang facilitate cooling.
