FEATURES
Design: Capable of grinding domestic sewage in
individual residential applications.
Cutter System: Anti-roping design. Two blade rotary
cutter is threaded to shaft. Stationary cutter ring is
reversible for extended service.
Impeller: Silicon bronze, semi-open, non-overloading
two-vane design with pump-out vanes for mechanical
seal protection. Balanced for smooth operation.
Casing: Cast iron, volute type for high efciency.
Adaptable for guide rail system.
Motor: Fully submerged in oil-lled chamber. High
grade turbine oil surrounds motor for more efcient
heat dissipation, permanent lubrication of bearings
and mechanical seal, and protection against outside
environment.
Motor Shaft: 300 series stainless steel, short overhang
for minimum shaft deection.
Designed for Continuous Operation: Pump ratings
are within the motor manufacturer's recommended
working limits, can be operated continuously without
damage when fully submerged.

File #LR38549
Bearings: Upper and lower ball bearings for precision
positioning of parts and to carry all radial and thrust
loads.
Mechanical Seal: Hardfaced Silicon carbide for longer
life, stainless steel metal parts, BUNA-N elastomers.
Power Cable: Severe duty rated, oil and water
resistant. Epoxy seal on motor end provides
secondary moisture barrier in case of outer jacket
damage and to prevent oil wicking.
O-Ring: Assures positive sealing against contaminants
and oil leakage.
Paint: Electro-coat paint process protects all casting
surfaces.
May be used with optional guide rail. See Fittings or
Pump Removal Systems.
