  • Corrosion-resistant, powder-coated epoxy finish
Notes

Product may not be exactly as pictured.

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.

Use optional model 10-1031 seal failure panel to enable moisture sensor circuit on automatic pump models.

Automatic units Patent No. 8,535,014

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

Warning

NOT FOR USE IN ACIDIC, METHANOL, OR ETHYL ACETATE ATMOSPHERES.

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).

Selection Guide

  1. See FM1705 for correct intrinsically-safe simplex or duplex panel.
  2. Variable level control switch 10-0225 used as a control activator, with electrical alternator duplex (3) or (4) float system.
  3. Integral float operated mechanical switch. No external control required. Seal failure indicator panel (10-1031) required for moisture sensors.
