Easy installation – Motor is normally supplied with 20' (6 m) of multi conductor, power cable and control cable as standard. Alternate cable lengths are available. Units have 3 legs as an integral part of pump housing for free standing requirements. Pump and motor assembly can be easily lowered into position, without disturbing the piping, by use of a rail system. Pump is furnished with a stainless steel lifting bracket.

Long-lasting, internal components – Special Class F insulation system rated for continuous duty in 130° F (54° C) liquids at 1.15 service factor. Thermal protection standard on all motors. Conservatively rated locked antifriction ball bearings for thrust loads. Finned motor housing for greater heat dissipation and cooler running motors.

Reversing cutter action – doubles cutter life vs. conventional grinders by allowing both sides of the cutter to work. Reversibility also allows the pump to clear troublesome jams and hangups thus reducing maintenance costs. Cutter and plate can be re-sharpened to extend pump life. Both are made of high-quality, stainless steel and hardened to a value of 55-60 on a Rockwell C scale. Protective cutter ring helps to extend cutter life. Capacitor start/capacitor run motor provides extra start and run torque for cutting.

Complete environmental protection – Buna-N O rings and heavy duty cord connectors keep liquid from entering the motor assembly. Motor housing is constructed of finned epoxy coated Class 30 cast iron. Hardware is stainless steel. Seal faces are carbon and ceramic for corrosion-resistance. Inner and outer seals provide complete protection for motor internals. Both have stainless steel and Buna-N components. Silicon carbide seal faces are available for those extra abrasive applications. Moisture detection system with upper and lower probes, protecting the motor from liquid entry. Vent hole helps prevent air locking. Balanced bi-directional ductile iron vortex impeller with top pump-out vanes for seal protection is keyed and bolted to the shaft. Concentric case with center discharge reduces radial loading for longer bearing and seal life. All pumps come with 1-1/4” NPT female vertical discharge. Pump is designed to provide same performance in both a clockwise and counterclockwise rotation of impeller/cutter assembly.
