Item # 4RH150M2-43, Standard 4" Non-Clog Wastewater Pumps

Capacity : 450 gpm (28.4 L/s)
Head : 30 ft (39.5 m)

Standard (4RH) and Explosion-Proof (4RHX) Construction
The 4RH and 4RHX (Explosion-proof) Submersible Wastewater Pumps are the right choice when difficult to pump fibrous or stringy solids are to be expected. The 4RH/4RHX series provides smooth, vibration-free operation when operating at heads higher than peak 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 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 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 burn-out.

Available with optional FM approval for use in Class 1, Groups C and D hazardous locations (4RHX only).
