The Myers P Series Effluent Pumps are designed specifically for today's multi-pump pressure collection and septic tank effluent pumping (S.T.E.R) systems and high head drainage applications. The P Series effluent pumps with their high efficiency single vane, enclosed impellers provide the steep non-overloading performance curves ideal for pressure collection and S.T.E.P systems. Myers 1/2 and 1 horsepower P Series pumps deliver more capacity at higher heads than most 1,1 1/2 and 2 horsepower pumps in their class. Myers P Series pumps are constructed of only the highest quality corrosion resistant materials like cast iron, stainless steel and thermoplastics to assure that they will perform for years to come in the harsh effluent environment end drainage applications.

Advantages By Design
Optimum performance for use in multi-pump pressure collection and S.T.E.P. systems
  • High efficiency, single vane, enclosed impeller provides non-overloading performance over entire range. Outperforms most pumps in its class.
  • Impeller passes 3/4 inch spherical solids.
  • Enclosed impeller design eliminates possibility of jamming or corrosion between impeller and volute.
Durable motor will deliver many years of reliable service
  • Oil-filled motor for maximum heat dissipation and constant bearing lubrication.
  • High torque, permanent split capacitor (PSC), single phase motors. No starting switches or relays to wear out.
  • Double tandem seal option for extra motor protection, tough effluent pumping applications.
  • Optional seal leak probe warns of seal leak condition. (Dual seal motors only.) Helps prevent costly motor damage.
  • On-winding current and temperature sensitive overload to protect against costly burnout due to overload.
The P series effluent pumps are designed for years of maintenance free operation
  • Volute seal ring is replaceable. Restores pump to original performance if wear should occur.
  • Motor is held in place by four screws. Easily removed if service is ever needed.
