The Haskel 8DSTVD-25 is a heavy-duty, 8?HP pneumatic liquid pump designed for demanding high-pressure applications. Featuring a 25:1 nominal (27.5:1 actual) pressure ratio, it can generate continuous output pressures up to 3,575?PSI (24.6?MPa). Equipped with a single air-drive head, stall-to-hold capability, and infinitely variable cycle speed, its ideal for fluid transfer, hydrostatic testing, and industrial process control. Built with stainless and bronze wetted parts and PTFE/Viton seals, the pump ensures longevity and compatibility with a broad range of liquids and liquefied gases.
- Air-driven no electricity required; operates cool and spark-free
- Delivers up to 3,575 PSI continuous pressure
- Stall-to-hold feature maintains pressure without continuous air use
- Variable cycling speed allows precise control
- Constructed with stainless steel, bronze, and Viton/PTFE seals for durability and chemical resistance
