Here's a look at some hydraulic pumps and related products available from the marketplace. The chart on page 50 lists manufacturers of these components, as well as specifications on the products they offer.

Series 500/550 hydraulic hand pumps feature heattreated steel linkage assemblies, Nitrotec treated pistons, multiple length operating levers for better ergonomics, and multiple seal options. Single stage units offer pressures to 10,000 psi with displacements ranging from 0.14 to 2.1 in. 3 Available with or without a fluid reservoir in a unique, modular configuration or manifold mounted to minimize plumbing. Two-stage pumps increase overall pumping efficiency by being able to deliver 2.1 in. 3 until 500 psi threshold, then switches to a lower displacement, ranging from 0.26 to 0.58 in. 3 for pressures to 5000 psi.
