Haskel ASF-100 Air Driven Fluid Pump

The Haskel ASF-100 is a high-pressure, air-driven liquid pump designed for reliable fluid transfer and pressurization in demanding industrial applications. Manufactured by Haskel International, this model features a 100:1 pressure ratio, allowing it to generate outlet pressures up to 15,000 PSI (label indicates 16,500 PSI, but standard specs confirm 15,000 PSI max) from a maximum air drive of 150 PSI. It is ideal for use in oil and gas, chemical processing, hydrostatic testing, and water jetting systems where explosion-proof operation is required, as it operates without electricity, reducing spark risks in hazardous environments. Key benefits include stall-proof operation, infinite flow variability, and compatibility with a wide range of fluids such as water, oils, and solvents. Compared to electric pumps, it offers superior safety in volatile settings and lower maintenance due to fewer moving parts, though it requires a compressed air source and may have lower efficiency in continuous high-flow scenarios. This unit, dated December 2011, shows signs of use but is in good working condition with no major damage visible. Drawbacks include potential noise from air operation and the need for regular seal maintenance in aggressive fluid applications. Overall, it's a robust choice for portable, high-pressure pumping needs.
