Axial piston hydraulic pump Eaton Hydraulics

M Series pumps are open circuit, axial piston designs. A variety of controls provides the ability to match the pumps to each application.

A strong, proven rotating group allows the pumps to handle pressures to 280 bar (4000 psi) continuous and 320 bar (4600 psi) intermittent - with less maintenance cost. Each frame can also contain a 230 bar (3300 psi) higher flow rotating group that provides additional application flexibility. High-load bearings and a stiff drive shaft help provide a pump life of 30,000 hours (@ 65% rated pressure), reducing operating costs and extending machine life.

M Series pumps feature a saddle-type yoke with steel-backed polymer bearings. The stiff yoke reduces deflection and allows even loading of bearings, improving life. A single control piston reduces loading on the yoke, resulting in reduced pump size that allows installation in tighter locations.

M Series pumps operate at a level of quietness that exceeds the requirements of today's demanding industrial conditions. The pumps feature a unique three-piece envelope (flange, housing and valve block) specifically created for low fluid-borne and structureborne noise levels. Another pump feature - a bimetal timing plate - improves pump filling characteristics that, in turn, reduces fluid-borne noise and extends pump life.
