The Haskel 4B-100 is a rugged, pneumatic-driven liquid pump delivering high-pressure performance without electricity or heat. Powered by compressed air, it features a 100:1 nominal pressure ratio (actual 114:1) and reaches up to 10,600?PSI (731?bar). Compact, reliable, and easy to automate, it stalls to hold pressure without running continuously and is compatible with various liquids and liquefied gases. Built with stainless steel and durable internal components, it's ideal for hydrostatic testing, fluid transfer, and hydraulic control applications.
