The Haskel DSHF-302 is a robust 2 HP double-acting pneumatic liquid pump featuring a 302:1 nominal ( 346:1 actual) ratio. Designed for high-pressure applications, it delivers continuous hydraulic pressures up to 30,000 psi, with intermittent performance up to 50,000 psi, using only compressed air ideal for hazardous or spark-sensitive environments. Its distance-piece structure allows stall-and-hold capability, maintaining pressure without consuming air. Built with stainless-steel piston and body, UHMWPE dynamic seals, and a 2" stroke, its engineered for durability, compactness, and reliability in demanding industrial settings.
