High Head (ME3H)

The Myers ME3 series are rugged 1/3 hp Effluent Pumps designed for demanding effluent pumping jobs where dependability is a must. The ME3 is constructed of only the highest quality corrosion resistant materials - like cast iron, stainless steel and engineered thermoplastics - to provide many years of service in the harsh effluent environment. The ME3 is available with a recessed impeller for high-head applications or an enclosed impeller for high-flow applications - both will pass a full 3/4" spherical solid. The ME3 is available in automatic models with piggyback mechanical float switch or manual models for use with external controls.

Advantages By Design
Durable motor will deliver many years of reliable service.
  • Oil-filled motor for maximum heat dissipation and continuous bearing lubrication.
  • Overload protected, shaded pole motor eliminates starting switches and relays which are prone to fail.
  • Heavy cast iron motor housing and volute case dissipate heat, allow motor to run cooler for extended life.
The ME3 is engineered for many years of maintenance-free operation.
  • Field tested, wide angle, mercury-tree mechanical float switch for maximum draw down. (Automatic piggyback models only).
  • Automatic pump models can be operated manually by unplugging piggyback switch and plugging pump directly into outlet.
  • Passes a full 3/4" solid.
