Single Stage, Centrifugal, Single Suction Impeller, Midship Mounted. The compact design means a lighter weight and smaller pump compartment, thus making more valuable space available on the truck. Darley did not cut corners in the design of this highly efficient pump with flows in excess of 1800 gpm from draft, and features the same durable MagnaTrans™ gearbox as our popular LDM pump. The PSM will provide years of reliable service, but in the event the pump does need service, the design allows for the quick access to the pump. The optional discharge check valve (pictured in assembly #2) allows for fast priming. The PS Series pump has been the choice of thousands of departments around the world – confidence you can count on.
