Haskel Model AW-B15 — 1.5 HP Air-Driven Liquid Pump

Haskel Model AW-B15 — 1.5 HP Air-Driven Liquid Pump

The Haskel Model AW-B15 is a high-capacity air-driven liquid pump engineered for demanding industrial operations requiring dependable high-pressure output. Featuring a nominal pressure ratio of 15:1 and a single air head design, the AW-B15 efficiently boosts liquid pressures up to 2400 PSIG, delivering both strong performance and exceptional operational reliability.

Built on Haskel’s proven pneumatic drive technology, the AW-B15 ensures safe and spark-free operation, eliminating hazards associated with heat or electrical ignition. Its infinitely adjustable cycling speed and ability to stall at a preset pressure without additional energy consumption make it ideal for continuous or intermittent pressure-holding applications. The pump’s robust construction, compact footprint, and low maintenance requirements provide long-term reliability in harsh industrial environments.

The AW-B15 is compatible with most liquids and liquefied gases, and can be customized with alternative drive gases such as sour gas, natural gas, boil-off gas, or nitrogen. Equipped with an unbalanced cycling spool for immediate response to system pressure changes and no required air-line lubrication, this pump delivers consistent performance while minimizing operating costs. Units can be manufactured to meet ATEX, CE, and NACE standards for enhanced safety and compliance.
