Tank Diameter

Gallons / Liters Pumped

18” (45.7 cm) simplex

8 gallons / 36 liters

24” (61 cm) simplex

15 gallons / 68 liters

30” (76 cm) duplex

22 gallons / 100 liters

36” (76 cm) duplex

33 gallons / 150 liters

48” (122 cm) duplex

60 gallons / 273 liters

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

** See charts for UL and CSA listings.

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.

Technical Data

CAUTION

All installation of controls, protection devices and wiring should be done by a qualified licensed electrician. All electrical and safety codes should be followed including the most recent National Electric Code (NEC) and the Occupational Safety and Health Act (OSHA).
Maximum temperature of sewage or dewatering must be limited to 130°F (54°C). For over 130°F (54°C) special quotation required.

SELECTION GUIDE

  1. Integral float operated mechanical switch, no external control required.
  2. For automatic use single piggyback variable level float switch or double piggyback variable level float switch. Refer to FM0477.
  3. See FM1228 for correct model of simplex control panel.
  4. See FM0712 for correct model of duplex control panel or FM1663for a residential alternator system.
