Darley is a proud manufacturer and supplier of industry leading pumps for use with firefighting and many other applications. Darley pumps are engineered for life to give a consistent pressure and flow while delivering dependability and affordability.

They have been working together as a family business for four generations with one mission in mind; which is to passionately serve the world’s first responders by providing high quality, safe, and innovative products with unmatched commitment and service.

In 2017, more fire departments switched to Darley Pumps than ever before. As an ISO 9001:2008 certified company, Darley’s rigorous engineering and testing requirements ensure that all pumps provide years of reliable service.

Longest Warranty

The company issues longest and most comprehensive warranty in the industry with a six year manufacturers.

Their 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.

AutoCool™ & Magnatrans™

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.

Self-Locking Discharge Valves

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.

Their 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.

Discharge Check Valve

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.

Vacuum Cast Impellers

Durable and efficient vacuum cast impeller, balanced to fit a 10-splined stainless steel pump. High lift, high flow, less porosity. Highly efficient twisted Francis vane vs a standard straight vane. Broached rather than keyed for maximum strength and durability and hand balanced for the smoothest possible dynamic performance.

Darley Cost of Ownership

Blending sophistication and ingenuity, Team Darley continues to develop the best pump efficiencies on the market. Utilizing computational fluid dynamics (CFD), we have the ability to bend the realm of possibility. We believe in providing unmatched service, unmatched performance, and unmatched quality while reducing the total cost of ownership to our customers.
