Designed for high head residential sewage applications where a gravity system is not practical. Ideal for pressure sewage systems.

Features and Benefits
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 efficiency. Adaptable for slide rail system.
Motor: Fully submerged in oil-filled chamber. High grade turbine oil surrounds motor for more efficient heat dissipation, permanent lubrication of bearings and mechanical seal, and protection against outside environment.
Motor Shaft: 300 series stainless steel, short over-hang for minimum shaft deflection.
Designed for Continuous Operation: Pump ratings are within the motor manufacturers recommended working limits, can be operated continuously without damage when fully submerged.
