The Waterous E500 Series Water Pump is specifically designed for mounting on specialized attack vehicles and available in two performance models, the E501 and E511. Providing versatility with high-pressure and high-capacity flow options, the E501 and E511 models dispense powerful water delivery, no matter the situation.

 

 

Waterous' high-pressure model, the E501-A, operates at a flow capacity up to 50 GPM (190 L/min) at 400 PSI (28 bar) and 110 GPM (420 L/min.) at 100 PSI (7 bar).

When compared with apparatus equipped with other brands of portable fire pumps, the power behind the E500 pumps can be repaired and back in service faster. Featuring a standard spring-loaded mechanical shaft seal that never needs adjustment, and backed by exclusive factory service and expert technicians, we've got your E500 pump service and maintenance needs under control.

 

 

Easily interfacing with numerous accessories, the Waterous E500 portable fire pumps come with a variety of options to fit the needs of your fire department. Priming system options are available, which include Waterous' hand and electric primers that are shipped loose for remote mounting. Single municipal, dual municipal (includes an In-cab panel) or deluxe control panels specifically designed for the E500 are also available.
