PSM 1000 – 2000 Midship Mounted Pump

PSM 1000 – 2000 Midship Mounted Pump

Centrifugal, Single Suction Impeller

The Darley PSM 2000 GPM pump is the most compact, durable, and efficient 2000 GPM pump on the market. The PSM Pump is NFPA can be rated from 1000 to 2000 GPM and is capable of flows well over 2200 GPM.

Designed by experts in fluid dynamics technology, the PSM utilizes the industry’s best silicon carbide mechanical seals, which is an extremely hard and heat dissipative material, resisting wear and dry running damage much better than conventional Ni-resist and Tungsten Carbide materials and has optional discharge check valve allowing for fast priming.

The gearbox is rated to handle 19,230 ft. lbs. of torque, and gears are helically cut to ensure quiet operation. The impeller is vacuum cast, eliminating porosity, and dynamically balanced to ensure smooth operation while spinning at over 4000 RPM.

Pumps are modularly built for easy service, and the compact design means a lighter weight and smaller pump compartment and features the same durable MagnaTrans™ gearbox as our popular LDM pump.

The PS Series pump has been the choice of thousands of departments around the world – confidence you can count on.
