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
