Long at higher temperatures and pressures
Oilgear's PVM open-loop, axial piston pumps offer a compact, computer-optimized unit with multiple controls available. They come in three frame sizes, with multiple displacements available for each. They last longer, run under higher pressure, and have a higher resistance to contamination through its "hard on hard" rotating group, which uses hardened steel shoes on a hardened swashblock surface. Composite materials are used in the hydrodynamic bearing support on the cylinder barrel, meaning it can take higher temperatures. The pumps can be used with low-viscosity or other special fluids. They can be easily converted between right and left-hand-driven pumps, and they are still easy to install. They offer a rugged cylinder design; lubricated saddle bearing; cylinder mount in polymerous journal bearing for high performance in high-cyclic applications; sealed front bearings; SAE heavy-duty spline and keyed shafts; running speeds up to 3,600 rpm; a maximum pressure of 4,250 psi (293,1 bar), and theoretical maximum displacements from 0.66 in3/rev (10,8 ml/rev) to 7.94 in3/rev (130,2 ml/rev).
