Each year more fire departments switched to Darley Pumps than ever before. As an ISO 9001:2015 certified company, Darley's rigorous engineering and testing requirements ensure that all pumps provide years of reliable service. With our pumps backed by the industry's longest warranty, it's no wonder that so many are Demanding Darley.
We understand the importance of keeping your pump operational, which is why we ship most Darley parts orders within 24 hours.
Our mechanical seal features an extremely hard (72 Rockwell) and heat dissipative silicon carbide stationary face. Resists wear and dry running much better than conventional Ni-resist and tungsten carbide materials. Now standard on all pumps except for double suction LDM and EM. Over 35,000 in service currently with an unparalleled service record.
Darley pump transmissions are the strongest in the market at 19,230 ft-lb torque rating and use helical cut gears as standard on all transmissions to limit noise and maximize strength. The patented AutoCool™ ensures oil cooling without the possibility of water contamination.
Darley’s exclusive heater core helps cool your apparatus’s engine in the warm summer months and help protect your pump from freezing in the harshest winter climates.
Since the 1960’s, Darley has been manufacturing the best discharge ball valve on the market. Designed with a self-locking feature, the valve allows for stable hands free operation. The valve also features a stainless steel ball and a bronze seat. Are you tired of replacing your ball valves year after year? Our ball valve can be rebuilt in minutes resulting cost savings and continued performance. Another added benefit of the Darley ball valve is the adjustable handle, which can be clocked in 45 degree increments to allow for varying applications.
Darley’s discharge check valve is designed to improve attack time. By isolating the discharge plumbing from the pump cavity, the pump can be primed with open discharge gates. When the pump achieves prime, the discharged water forces the check valve to an opened position. The simplicity of the design allows for easy maintenance and trouble free operation.
Darley twisted vane impellers are vacuum cast to eliminate porosity, broached to fit a 10-splined shaft rather than a single key and precision balanced for smooth operation and optimal efficiency all resulting in reduced cost of ownership and the most efficient and durable fire pump on the market.
Our pump division is registered as an ISO 9001: 2015 Certified facility, accredited by Underwriters Laboratories Inc.
