X290 Series Sewage Pumps

Submersible effluent or dewatering pumps with explosion-proof motors.

Features and Benefits

  • cCSAus rated Class I, Division 1, Groups C & D and Class Zone 1, Groups IIA & IIB Construction
  • Tested to FM standards 3600 and 3615 by CSA
  • Automatic or non-automatic. Automatic units Patent No. 8,535,014
  • Non-clogging vortex impeller design, bronze class 88-8-0-4
  • Stainless steel bolts, handle, guard and float rod guide, switch arm and actuator assembly
  • Brass float and float rod (automatic only)
  • Durable, cast construction. Cast iron cover, motor adapter and pump housing. No sheet metal parts to rust or corrode. All cast iron class 30, 30000# tensile strength.
  • Stainless steel screws and handle
  • 20' (6 m), UL listed, 5-wire (1 Ph) or 8-wire (3 Ph) neoprene cord. Extra cord lengths available in 25', 35' and 50' (8 m, 11 m and 15 m) length only. Sensor leads and power leads in one cord for easy installation.
  • Threaded conduit connection for protecting cords in extra heavy-duty applications: 1-1/2" NPT.
  • Moisture sensors pre-wired in motor housing (functionality requires indicator circuit in panel)
  • Zoeller control panel with intrinsically-safe relays and moisture indicator is required with non-automatic units
  • Simplex seal-fail panel #10-1031 available for automatic units
  • 3 Ph models available as non-automatic only
  • Motor - 3450 RPM, oil-filled, hermetically-sealed, automatic reset thermal overload protected (3 Ph requires circuit in control panel)
  • Maximum temperature for sewage or dewatering: 104 °F (40 °C)
  • Shaft seal: stainless steel wetted parts, carbon and ceramic rotary face seal
  • Upper ball bearing and lower ball bearing running in bath of oil
  • Neoprene square ring seals
  • All models pass 2” (50 mm) spherical solids
  • Major width: 13-5/16" (33.8 cm)
  • Height: 23-9/32" (59.1 cm) (nonauto), 24-15/16" (63.3 cm) (auto)
  • When ordering, specify 2” or 3” NPT female flanged vertical discharge
  • 100% computerized testing and 100% tested submerged in water
  • Corrosion-resistant, powder coated epoxy finish

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.

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.

Technical Data

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, quantity required dependent upon panel selection

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).
Model 293 should not be subjected to less than 15 TDH.

Warning

Not for use in acidic, methanol or ethyl acetate atmospheres.
