Item # MW50, Myers® MW50 Series 2" Solids Handling Sewage Pumps



Capacity : 135 gpm (510 lpm)
Head : 27 ft (8.23 m)


1/2 Horsepower

The Myers MW50 Series Sewage Pumps provide big performance in a small package. The enclosed two-vane impeller provides the flow and head required for residential and light commercial sewage applications, and passes a full 2" diameter solid. The MW50 is constructed of only the highest quality corrosion resistant materials - cast iron, stainless steel and engineered thermoplastics - for many years of service in harsh sewage environment. The MW50 is available in manual models for use with external controls or automatic models with piggyback mechanical float.

Advantages By Design
Two vane impeller design provides maximum efficiency
  • Enclosed design for high efficiency pump.
  • Eliminates possibility of jamming between impeller and volute.
  • Passes a full 2 inch solid.
  • Original performance can be restored if wear occurs by replacing volute seal ring.
Durable motor will deliver many years of reliable service
  • Oil-filled motor for maximum heat dissipation and constant bearing lubrication.
  • Permanent split capacitor motor eliminates starting switches and relays which are prone to fail.
The MW50 is designed for many years of maintenance free operation
  • Positive sealing, quick connect power cord and piggyback float switch make replacement simple if service is ever necessary.
  • Field tested, wide angle, mercury-free mechanical float switch provides maximum draw down. (Automatic models only.)
  • Long flexible Type 6 seal provides high pressure sealing with improved seal face protection by location.
  • Lower ball bearing eliminates sleeve bearing wear and significantly reduces motor wear.
  • Low amp draw from the efficient PSC motor means less heat build-up.
