Myers® 4R and 4RX Series 4" Non-Clog Wastewater Pumps
Myers® Solids Handling Pumps
Capacity : 565 gpm (35.7 L/s)
Head : 57.5 ft (17.5 m)
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.

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.
- 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.
