Submersible Propeller Pump
F e a t u r e s
Watertight cable entry system prevents capillary action and protects against moisture; reduces maintenance costs Junction area includes a terminal board for cable connections allowing for fast efficient replacement; area sealed from the stator housing; prevents leakage into the motor; reduces the possibility of failure Heavy duty, high efficiency, air filled motor, Class F insulated, rated for 311F with a 1.15 service factor dissipates heat easily; thermal protection in each phase of windings protects; operates cooler with higher efficiencies; longer service life with lower operating costs Double and triple row grease bearings carries thrust loading with L-10 life of 100,000 hours; ensures long, dependable operation and lowers maintenance costs Float type leakage detector provides early warning of mechanical seal failure; avoids costly motor repairs Cartridge type, duplex mechanical seals assembled in tandem arrangement; easy maintenance and high reliability High efficiency, axial flow impellers accept large diameter solids; lowers operating costs Replaceable case liner maintains working clearances while lowering case replacement costs
