130 Series Effluent Pumps

130 Series Effluent Pumps

Effluent Pumps

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

130 Series Effluent Pumps from Zoeller Pump Company can move your grey water and pass spherical solids of 5/8 inches or less. During operation, the pump uses centrifugal force to push fluid against the volute. The fluid being pumped doesn’t contact the impeller vanes, offering a reliable way to move water with minimal risk of clogging.

Installed through an easy and straightforward process, these submersible pumps lower into a sump pit. Features such as hermetic sealing and an automatic thermal overload offer protection and keep the system running smoothly. The design includes durable cast iron construction and offers corrosion resistance thanks to a powder-coated epoxy finish. For long-term strength and performance, the bolts, screws, guard, handle, arm, and seal are all stainless steel.

Customizations you can request include variable-level control switches and control alarm systems. These features can automatically monitor water levels, giving you peace of mind about the status of your system.

Consult Factory for Special Application

  • Electrical alternators for duplex systems are available and supplied with an alarm
  • Mechanical alternators for duplex systems are available with or without alarm switches
  • Simplex panels are available for 3 Ph pumps
  • Control alarm systems are available for 1 Ph pumps
  • Variable level control switches are available for controlling 1 and 3 Ph systems
  • Double piggyback, variable level float switches are available for variable level long cycle controls
  • Over 130 °F (54 °C) – special quotation required
  • Consult factory for temperatures over 130 °F (54 °C)


The sizing of effluent systems normally requires variable level float(s) controls and properly sized basins to achieve required pumping cycles or dosing timers with non-automatic pumps.

Pumps must be operated in upright position.

Reserve Powered Design.

For unusual conditions a reserve safety factor is engineered into the design of every Zoeller pump.
