Standard (4VHA) and Explosion-Proof (4VHAX)

The high head 4VHA and 4VHAX (Explosion-proof) submersible non-clog Wastewater Pumps feature heavy duty construction and high operating efficiencies. Myers rounded port, 2-vane, enclosed impeller prevent solids from binding or clogging and offer high operating efficiencies to cut your pumping costs. The 4VHA series constant velocity volute provides smooth operation over an extended portion of the performance curve for longer seal and bearing life. For use in raw water, storm water, effluent and drainage applications. Myers offers a complete line wastewater pumps, lift-out rail assemblies, controls and accessories to meet your needs.

Advantages By Design
High efficiency hydraulic design cuts pumping costs and extends life of fluid end components.
  • Two-vane, rounded port, enclosed type impeller operates at high efficiencies.
  • Modified constant velocity volute offers quiet operation, low radial loads over extended portion of performance curve.
Durable motor will deliver many years of reliable service.
  • Oil-filled motor for maximum heat dissipation and constant bearing lubrication.
  • Heat sensor thermostats imbedded in windings protect motor from overheat conditions.
  • Seal leak probes warn of moisture entry; helps prevent costly motor burn-out.
  • Double tandem shaft seals prevent sewage from entering motor.
  • Power and control cables are double sealed with epoxy and compression grommet.
Available with optional U.L. approval for use in Class 1, Group D hazardous location (4VHAX only).
