The Haskel ASF-122 is a 2?HP pneumatic-driven liquid pump with a rugged stainless steel body and UHMWPE seals. Operating on compressor air, it delivers hydraulic pressures up to 15,000?psi, with a sealed design that eliminates heat, sparks, or flame hazards. Its stall-and-hold feature maintains target pressure without consuming extra air, making it ideal for hydrostatic testing, fluid transfer, or clamping. Compact and ATEX-certified, it supports automated setups and long-duration pressurization without contamination.
- Operates on compressed air no electric motor or heat
- Reaches design pressures up to 15,000 psi (122:1 ratio)
- Stall-and-hold maintains pressure indefinitely without air usage
- Stainless steel piston and body resist corrosion
- ATEX certified and infinitely adjustable via drive-air control
