Introduction
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 and320 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 structure-borne noise levels.Another pump feature-a bimetaltiming plate-improves pump filling characteristics that,in turn,reduces fluid-borne noise and extends pump life.
An adjustable maximum stop provides a means of tuning flow to your system,while gauge ports allow monitoring of inlet and outlet conditions.These standard features reduce system complexity and cost.
Mounting flanges are offered in SAE and ISO con-figurations,and ports are offered in SAE,ISO,and BSPP in both tube and flange versions.This provides a wide variety of installation opportunities for global machine design.
Side-or end-ported models are available to facilitate plumbing and help fit the pump to your machine space needs.Multiple drain ports allow many mounting orientations,reducing installed costs.
M Series pumps are capable of operating with many types of hydraulic fluids used in industrial and mobile systems.High-water-content and phosphate ester fluids can be accommodated,in addition to the typical petroleum based and synthetic fluids.
With an M Series pump you can have smaller and quieter power units at higher pressures,using higher speed(1500 and 1800 r/min)electric motors.Your systems willhave lower vibration levels on the system piping,helping to ensure a leak-free system.
