The Haskel DSHF-300 is a high-performance 1.5?HP pneumatic liquid pump designed to deliver hospital-grade hydraulic pressure with no electricity or sparks. Boasting a nominal 300:1 ratio (actual ~345:1), it generates up to 30,000?psi continuous and 50,000?psi intermittent output using clean compressed air. Ideal for hydrostatic testing, calibration, and clamping, its double-acting distance-piece design includes a stall-and-hold capability to maintain pressure without consuming air. Constructed with stainless-steel piston, body, and UHMWPE seals, the DSHF-300 is durable, compact, and built for rugged industrial environments.
- 1.5?HP pneumatic double-acting design delivering reliable high-pressure flow
- Nominal 300:1 ratio provides up to 30,000?psi continuous, 50,000?psi intermittent
- Stall-and-hold feature maintains peak pressure without air usage
- Stainless-steel body and UHMWPE seals ensure corrosion resistance
- Compact 2" stroke design with distance piece reduces contamination and enhances longevity
