Standard (3RH) and Explosion-Proof (3RHX) Construction

Myers 3RH and 3RHX (explosion-proof) submersible wastewater pumps are the right choice when difficult to pump fibrous or stringy solids are to be expected.The 3RH/3RHX series provides smooth, vibration-free operation when operating at heads higher than peek efficiency. For use in commercial 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 not 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 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 F.M. approval for use in class 1, Groups C and D hazardous locations (3RHX only)
