The Haskel MSHP-220 is a compact 0.33?HP pneumatic-driven liquid pump engineered to deliver up to 20,000?psi continuous (25,000?psi intermittent) from compressed air (?125?psi). Built with a stainless-steel piston and body, it features a smooth stall-and-hold valve that retains system pressure without consuming air. Its impressive 220:1 ratio (actual ~237:1) supports ultra-fine, low-volume fluid control, making it perfect for hydrostatic testing, calibration, clamp actuation, or any situation requiring high-pressure precision without electricity. Durable, portable, and safe for hazardous environments.
- Delivers continuous 20,000?psi pressure from shop air
- Compact, durable stainless-steel wetted design ideal for corrosive environments
- High ratio 220:1 nominal (?237:1 actual) enables precise low-flow control
- Stall-and-hold valve retains generated pressure without air input
- Variable cycle speed and no need for air-line lubricants
