• 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 , Class F insulated, rated for 311°F with a 1.10 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

• Self cooling jacket eliminates the need for external pumping devices or special heat transfer fluids;offers simplicity and high reliability by effectively dissipating heat

• Double and triple row lubricated bearings carry 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, closed mixed flow impellers large diameter solids; lowers operating costs

• Replaceable case liner ring maintains workingclearances while reducing casing costs
