Item # ME40, Myers® ME40 Series Effluent and Drain Water Pumps

Capacity 60 gpm (227 lpm)
Head : 32 ft (9.75 m)

4/10 HP

The Myers ME40 series effluent pumps are one of the most efficient 4/10 HP pumps on the market today. The enclosed two-vane impeller provides the flow and head required for today's dosing systems and the many tough drainage applications. The ME40 is constructed of only the highest quality corrosion resistant materials - like cast iron, stainless steel and thermoplastics - for many hours of service in the harsh effluent environment. The ME40 is available in automatic models with piggyback or built-in mechanical float switch or manual models for use with external controls for precise dosing.

Advantages By Design
Two-vane impeller design provides maximum dosing efficiency
  • Enclosed design for high efficiency pumping.
  • Full 3/4 inch passageway.
Durable motor will deliver many hours 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.
The ME40 is designed for many hours of maintenance free operation
  • Positive sealing, quick connect float and switch cords make replacement simple if service is ever necessary.
  • Field tested, wide angle, mercury-free mechanical float switch provides maximum draw down. (Automatic models only)
  • Piggyback equipped automatic models allow pump to be run manually by unplugging switch and plugging pump directly into outlet.
  • Long, flexible Type 6 seal provides high pressure sealing with improved seal face protection.
  • Lower ball bearing eliminates sleeve bearing wear and holds the mechanical seal steady.
