The Haskel DXHF-452 is a rugged 2?HP pneumatic liquid pump engineered with a distance-piece, multi-head air drive. With a 452:1 nominal (?520:1 actual) ratio, it delivers hydraulic pressures up to 30,000?psi continuous and 70,000?psi intermittent purely using shop air no electricity or sparks. Stainless steel construction with UHMWPE dynamic seals ensures corrosion resistance and long-term durability. Featuring stall-and-hold pressure retention and infinitely variable flow control, this pump excels in demanding applications like bolt tensioning, hydrostatic testing, precision fluid transfer, and clamp actuation in explosive or remote environments.
- Boosts up to 30,000?psi continuous, 70,000?psi intermittent hydraulic pressure
- High 452:1 ratio with multi-head design for improved performance and reduced air consumption
- Stall-and-hold distance piece ensures maintained pressure without ongoing air use
- Durable stainless steel body and UHMWPE dynamic seals optimize corrosion resistance
- Adjustable cycle speed and compact form factor, perfect for field and automated systems
