Technical Information

The Right Choice

The 4RC and 4RCX (explosion-proof) submersible wastewater pumps are the right choice when difficult to pump fibrous or stringy solids are to be expected. The 4RC/4RCX series provides smooth, vibration-free operation when operating at heads higher than peak efficiency. The pump is for use in municipal lift stations, treatment plants and industrial waste water applications.

Myers offers a complete line of wastewater pumps, lift-out rail assemblies, controls and accessories to meet your needs.

Passes stringy trash, fibrous wastes, slurries, and other difficult to pump solids that standard enclosed or semi-open impellers cannot.
  • 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 shutoff without harming pump.
Durable motor will deliver many years of reliable service.
  • Recessed impeller greatly increases bearing life by reducing radial load.
  • 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 burnout.
Available with optional FM approval for use in Class 1, groups C and D hazardous locations (4RCX only).
