Product Overview

840 Grinder Pump
Features
The Shark
®
series of submersible grinder pumps is designed for use in
residential or commercial wastewater applications and can be used to transfer
raw sewage. Each pump features an innovative cutting mechanism, allowing it
to grind solids into fine particles. When used in conjunction with a properly
equipped control panel, the Model 840 utilizes an automatic reversing cutter,
which doubles the service life of a single-direction grinder and prevents
clogging. The uniform consistency of the discharged material reduces the risk of
clogs in the pipe, yielding less down time and fewer service calls. These durable
cast iron pumps include a powder coated epoxy finish to prevent corrosion, and
are designed to provide great heat dissipation from the motor, ensuring a long
service life. As with every Zoeller
®
pump, each one is 100% pressure-tested,
submerged and run to ensure quality and reliability for years of trouble-free
performance! This attention to detail is an inherent feature of every pump in this
series, making it one of the most reliable in the industry.
Each pump features a hardened, stainless steel cutter and cutter plate,
Rockwell C55-60.
Easily adapts to existing rail systems, or available in a preassembled
package.
Includes a stainless steel handle for easy installation and removal.
All models are hermetically sealed to be watertight, dust-tight, and completely
submersible.
