Series 45 open circuit pumps can be applied with other products in a system to transfer and control hydraulic power.
Series 45 pumps provide an infi nitely variable fl ow rate between zero and maximum.Series 45 variable displacement pumps are compact, high power density units, using the axial piston concept in conjunction with a tiltable swashplate to vary the pump displacement. Series 45 pumps use a cradle swashplate design. A hydraulic control piston sets the swashplate angle. Control of the displacement piston is provided through a built-in pressure compensator valve. This valve will vary the swashplate angle from its maximum to its minimum position when the set pressure is reached. Controls are also available for remote compensating and load sensing systems. An available displacement limiter (frame G and H units only) allows adjustment of maximum fl ow to match .
