The Enerpac P39 is a single-speed, steel hydraulic hand pump designed for reliable 10,000 psi power in field maintenance, industrial repair, and controlled lifting applications. Part of Enerpac’s ULTIMA series, the P39 is engineered for durability, portability, and consistent high-pressure output when a compact, manual pump is the most efficient solution.
Ultima Steel Hand Pumps are durable, portable, and highly efficient. Each model in the series features an all-steel construction, a chrome plated plunger, and a wiper system for long-lasting performance.
All except the P39 are 2 stage pumps, which reduces the number of handle strokes by as much as 78% compared to a single speed pump. This is ideal for applications when high flow is needed at the first stage, (such as when advancing a cylinder to the point of load contact). The pump switches automatically to the second stage which is the low flow high-pressure stage.
With a choice of oil capacities up to 453 in3 (7423 cm3), you will find Ultima Steel Hand Pumps that can handle multiple cylinder hook-ups, including models to suit either single-acting and double-acting cylinders.
