160 Series Sump and Effluent Pumps


160 Series Sump and Effluent Pumps

Commercial Use Sump and Effluent Pumps

Effluent or dewatering submersible pumps for septic tanks, low pressure pipe (LPP) and enhanced flow STEP systems.

Our 160 Series pumps are robust, high-performance solutions suitable for various commercial applications, including septic tanks, low-pressure pipes (LPP), or enhanced flow STEP systems.

These heavy-duty sump and effluent pumps are constructed from durable cast iron with a corrosion-resistant, powder-coated epoxy finish. Together with their no-clog vortex impeller, these elements give you a commercial sump pump you can count on for smooth, reliable operation.

Whether you choose an automatic or nonautomatic configuration, you can expect these pumps to maintain 3,450 rpm and pump out 100 gallons per minute. Each device we offer undergoes rigorous computerized testing and comes with a one-year limited warranty to give you peace of mind.

Other features include:

  • A max temperature of 130 degrees Fahrenheit.
  • The ability to pass ¾-inch spherical solids.
  • Hermetic seals.
