Introduction Eaton M Series Pumps are open circuit, axial pis- vides a wide variety of installation opportunities for ton designs. A variety of control options allows global machine design. the Pumps to perform most efficiently in a specific Side- or end-ported models are available to facilitate application. Efficiency of the pump controls allows plumbing and help fit the pump to your machine down-sizing of system cooling needs, saving up space needs.

Low installed and operating costs M Series Pumps operate at a level of quietness that Reduced maintenance exceeds the requirements of today's demanding Flexibility in machine work conditions. The Pumps feature a unique three- design piece envelope (flange, housing and valve block) Design promotes leak-free specifically created for low fluid-borne and struc- system ture-borne noise levels.

6 Another pump feature a bimetal timing plate improves pump filling charac- teristics which, in turn, reduce fluid-borne noise and extend pump life. M Series Pumps reduce, or in some cases remove, the need for damping barriers between the noise source and the operator. This saves money on the installed cost of the system while improving cus- tomer comfort. 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.
