The Haskel 4B-14 is a pneumatic liquid pump designed for high-pressure applications without electricity or heat. With a 14:1 nominal pressure ratio (actual 16:1), it delivers up to 1,500?psi continuous output, making it ideal for hydrostatic testing, fluid transfer, and dosing. It features a compact, stall-to-hold design saving energy and maintaining pressure when idle. Made with stainless steel and durable seals, the 4B-14 supports a wide range of liquids and liquefied gases in demanding industrial environments.
- Runs on compressed air no electricity or ignition risk
- Raises pressure up to 1,500 psi (103 bar)
- Stall-to-hold feature keeps pressure without air use
- Infinitely variable cycle speed for accurate control
- Corrosion-resistant stainless steel wetted parts
