The Haskel MHP-21 is a compact, manually operated version of the M-Series liquid pump designed for clean, controlled hydraulic applications. With a 21:1 ratio (actual around 25:1), it delivers up to 2,600 psig using manual leverage rather than air, ideal for portable pressure testing, calibration setups, or small-volume fluid transfer. The spring-return mechanism includes a stall-at-pressure feature holding preset pressure without additional pumping. Constructed from stainless/plated steel and PTFE/Buna-N seals, it's built for easy maintenance. It s an excellent choice where power or compressed air isn't available.
- Manual lever drive no air or electricity needed, ideal for field service or bench-top use
- Maximum pressure: 2,600 psig / 179 bar
- Displacement: ~0.20 in (3.3 mL) per stroke
- Stall-at-pressure function holds pressure without further effort
- Durable stainless/plated steel construction with PTFE/Buna-N seals
