The Haskel HSF-151 is a rugged 1.5?HP air-operated liquid pump with a 151:1 nominal (?173:1 actual) pressure ratio. Powered solely by compressed air, it delivers up to 25,000?psi continuous hydraulic pressure reliably and Safely ideal for hazard-prone environments, as it produces no sparks or heat. Its stainless-steel piston and body with UHMWPE dynamic seals ensure durability, while the 2" stroke and stall-and-hold design enable pressure retention without consuming air. Compact and efficient, it's perfect for hydrostatic testing, calibration, clamping, and fluid transfer applications.
- Delivers up to 25,000?psi continuous pressure using compressed air only
- 1.5?HP single-air-head design for strong, consistent output
- Stall-and-hold distance-piece locks pressure without air consumption
- Stainless-steel body/piston with UHMWPE seals for durability
- Variable cycle speeds (up to 60?cpm) allow flow/pressure adjustment
