The Haskel ASF-72 is a 2?HP pneumatic liquid pump with a 72:1 pressure ratio, designed to generate hydraulic output up to 11,000?psi. It operates on compressed air eliminating heat, sparks, and flame making it safe for hazardous environments like labs or ATEX zones. Compact, corrosion-resistant, and equipped with a stall-and-hold feature, the ASF-72 is ideal for hydrostatic testing, calibration, fluid transfer, or bolting operations requiring sustained pressure.
- Air-powered operation eliminates electrical hazards
- Dual-acting piston delivers high-pressure output
- 72:1 ratio generates up to 11,000 psi hydraulic pressure
- Stall-and-hold maintains pressure without air consumption
- Built with stainless steel and UHMWPE seals for chemical resistance and durability
