  • Simplex and duplex systems available
  • Automatic and non-automatic models available
  • Non-automatic for variable level systems
  • Models available packaged with piggyback variable level float switch

Consult factory for special applications:

  • Electrical alternators for duplex systems available with variable level float switches.
  • Minimum recommended basin size - simplex: 18” x 30” (45.7 x 76.2 cm), duplex: 30” x 36” (76.2 x 91.4 cm)
  • Standard automatic – 4/10 HP, 34.5 lbs.(15.6 kg)
  • High water alarms available
  • Mechanical alternators available for duplex systems
  • The approximate gallons pumped out per cycle for standard models are:

Tank Diameter

Gallons / Liters Pumped

18” (46 cm) simplex

8 gallons / 36 liters

24” (60 cm) simplex

15 gallons / 68 liters

30” (76 cm) duplex

22 gallons / 100 liters

36” (91 cm) duplex

33 gallons / 150 liters

48” (122 cm) duplex

60 gallons / 273 liters

Notes 
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.

Reserve powered design.

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

*May be used in those states where codes do not restrict solids size in effluent systems.
