Standard (4R) and Explosion-Proof (4RX) Construction

The 4R and 4RX (Explosion-proof) Submersible Wastewater Pumps are the right choice when difficult to pump fibrous or stringy solids are to be expected. the 4R series provides smooth, vibration-free operation when operating at heads higher than peek efficiency. 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
Passes stringy trash, fibrous wastes, slurries, and other difficult to pump solids that standard enclosed or semi-open impellers can not.
  • Recessed impeller design has completely open passage in volute.
  • Pumping action is by vortex; solids can't get caught in impeller volute.
  • Operates without vibration or cavitation over entire performance curve. Operates near shut-off without harming pump.
Durable motor will deliver many years of reliable service
  • Recessed impeller greatly increases bearing lilt by reducing radial load.
  • 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 burnout.
Available with optional U.L. approval for use in Class 1, group D hazardous locations (4RX only).
