  • Oil-filled and hermetically-sealed, automatic reset thermal overload protected (1 Ph) motor
  • Upper and lower sleeve bearings running in bath of oil
  • Carbon and ceramic shaft seal
  • Stainless steel screws, bolts, guard, handle, arm and seal assembly
  • Maximum temperature for effluent or dewatering: 130 °F (54 °C) (extra duty: 140 °F / 60 °C)
  • Passes 5/8” (16 mm) spherical solids
  • No screens to clog
  • 1-1/2” NPT discharge (1-1/2” x 2” PVC Adapter fitting included with BN and BE Models)
  • On point: 10” (25.4 cm)
  • Off point: 2-3/4” (7 cm)
  • Simplex and duplex package systems available
  • Variable level control systems available, designed for heavy-duty effluent applications
  • Automatic and non-automatic models available

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.
