The Haskel MSHP-36 is a compact stainless-steel pneumatic liquid pump delivering up to 4,500 psi using only clean air ( 125 psi drive pressure). Featuring a 36:1 nominal ( 41:1 actual) ratio, it offers precise, low-volume liquid displacement (~0.12 in per cycle). Its robust single-air-head design and stall-and-hold valve ensure pressure retention without continuous airflow. Built for field, test, and lab environments, its ideal for hydrostatic testing, clamp activation, and fluid transfer applications.
- Pumps up to 4,500 psi continuous pressure using air only
- Compact and spark-free pneumatic drive no electricity required
- Stall-and-hold mechanism maintains pressure without air consumption
- Precise single-cycle displacement (~0.12 in) for fine control
- Durable stainless-steel body and optional seal materials for longevity
