Standard (4VHS) and Explosion-Proof (4VHSX) Construction

The 4VHS and 4VHSX (Explosion-proof) Submersible Wastewater Pumps are a heavy-duty 4" non-clog series capable of passing a full 3" spherical solid. Myers single vane impeller prevents solids from binding or clogging and offer high operating efficiencies to cut your pumping costs. The 4VHS series modified constant velocity volute case provides smooth operation over an extended portion of the performance curve for longer seal and bearing life. For use in municipal lift stations, treatment plants and industrial waste applications. Myers offers a complete line of 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.
  • Single vane impeller provides a steeper, non-overloading performance curve and handles 3" solids with ease.
  • Modified constant velocity volute offers quiet operation, and 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 over heat 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 locations (4VHSX only).
