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. Reduced handle effort and ergonomic grip for less operator fatigue Vent free reservoir eliminates spills Quick grip handle allows for easy transport Integral reservoir over-pressurization protection
