Product Description Product OverviewRexroth piston pumpPlunger pump is an important device in hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder block to change the volume of the sealing working cavity to achieve oil suction and pressure. The piston pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. FEATURES AT A GLANCEWorking principle of piston pumpThe piston pump is divided into two representative structural forms: axial piston pump and radial piston pump; Because radial piston pump is a new type of high-efficiency pump with high technology content, radial piston pump will become an important part of the application field of piston pump; Radial piston pump is a kind of piston pump whose reciprocating motion direction is perpendicular to the driving shaft.The oil flow in and out of the pump body and the flow passage on the valve shaft are controlled by the oil suction port on the valve shaft. The liquid pressure generated in the pump body is absorbed by the surface of static pressure balance.

The sum of single operating periods must not exceed the total operating period.Single operating period2 msTotal operating period300 hMinimum pressure pB absolute (high-pressure side)10 barMinimum pressure on the high-pressure side (B) which is required in order to prevent damage to the axial piston unit. Rate of pressure change RA max16000 bar/sMaximum permissible pressure build-up and reduction speed during a pressure change across the entire pressure range.Pressure at suction port S (inlet)Minimum pressure pS min Standard0.8 bar absoluteMinimum pressure at suction port S (inlet) which is required to prevent damage to the axial piston unit. The minimum pressure depends on the rotational speed and displacement of the axial piston unit.Maximum pressure pS max10 bar Case pressure at port L, L1Maximum pressure pL max2 bar absolute Maximum 0.5 bar higher than inlet pressure at port S, but not higher than pL max. A drain line to the reservoir is required.Pilot pressure port X with external high pressure Maximum pressure pmax350 barWhen designing all control lines with external high pressure, the values for the rate of pressure change, maximum single operating period and total operating period applicable to port B must not be exceeded.
