50 Series
Features
The "Mighty-Mate" series of submersible pumps is designed for use in
residential or light commercial dewatering applications and can be used to
transfer groundwater or effluent. Cast iron models 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.
Automatic models include a float-operated, 2-pole mechanical switch, a
stainless steel float guard and switch arm, and a solid, buoyant polypropylene
float, which prevents water from filling the float and causing a malfunction.
For nonautomatic pumps, variable level control systems and containers of
various sizes are available for longer cycles.
Includes a stainless steel handle for easy installation and removal.
All models are hermetically sealed to be watertight, dust-tight, and completely
submersible.
Reserve Powered Design: For unusual conditions, a reserve safety factor is
engineered into the design of every pump.
