The Haskel AW-B52 is a 2?HP pneumatic-driven liquid pump with a nominal 52:1 ratio and actual area ratio of approximately 57:1. It delivers hydraulic pressure up to 8,000?psi (552?bar) using only compressed air eliminating sparks, heat, and flame risk. Featuring a stall-and-hold functionality, it maintains target pressure without consuming drive air, making it ideal for hydrostatic testing, fluid transfer, calibration, bolting, and clamping in industrial or hazardous environments. Built with a stainless-steel body, UHMWPE seals, and ATEX-compatible construction, it ensures durability and safety for demanding applications.
