WG30-50 grinder pumps are available in standard and U.L. Listed explosion-proof (WGX30-50) construction for use in Class 1, Group D hazardous locations.

WG30-50 grinder pumps can be installed in a variety of packaged systems. Factory-assembled simplex or duplex packages with guide rail systems are available. Individual rail components are also available for installation in on-site concrete systems. F E. Myers offers a complete line of submersible sump, sewage effluent, grinder, non-clog wastewater pumps, controls, basins and accessories.

Advantages by Design
Ideal for use in Lift Stations
  • Recessed impeller provides steep non-overloading operating curve.
Durable Motor will deliver many years of Reliable Service.
  • Oil-filled motor for maximum heat dissipation and constant bearing lubrication.
  • Recessed impeller reduces radial bearing loads increases bearing life.
  • High torque capacitor start/run single phase or three phase motors for assured starting under heavy load.
  • Seal leak probes and on-winding heat sensors warn of seal leak condition, and stop motor if motor overheats.
    Helps prevent costly motor damage.
The WG30-50 Series is designed for easy maintenance.
  • Shredding ring and grinder impeller are replaceable without dismantling pump or motor.
