Product Description

Enerpac lightweight hydraulic hand pumps are a convenient alternative to heavier steel pumps without any sacrifice in performance or safety. Each model is rated up to 10,000 psi (700 bar).

The durable glass-filled nylon reservoir and nylon encapsulated aluminum pump base offers an unrivalled combination of strength, weight, and resistance to corrosion.  

Lightweight single-speed hydraulic hand pumps offer the simplicity needed for a wide range of industrial applications. The 2-stage hydraulic models reduce the number of handle strokes by as much as 78% compared to a single speed pump. This is ideal when you want to advance a tool such as a cylinder to the point of load contact. High flow is delivered when it’s needed most before the pump automatically switches to the low flow high-pressure stage.

With a choice of oil capacities up to 453 in3 (7423 cm3), we’re certain you’ll find a lightweight hydraulic hand pump to handle multiple cylinder hook-ups. For compatibility with double-acting tools choose the P842.
