We supply Sauer Axial Piston Pumps series 90 series, 40 series and MPT025 MPT035 MPT044 MPT046 MPV025 MPV035 MPV044 MPV046. MPT025C MPT035C MPT044C MPT046C MPV025C MPV035C MPV044C MPV046C.
its compact, high power density units.
All models utilize the parallel axial piston / slipper concept in conjunction with a tiltable swashplate to vary the pump's displacement. Reversing the angle of the swashplate reverses the flow of fluid from the pump and thus reverses
the direction of rotation of the motor output.
Details regarding the choice of hydraulic fluid
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in
a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than 115 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.
Hydraulic fluid
Before starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions. The variable pump A4VG is unsuitable for operation with HFA, HFB and HFC. If HFD or environmentally acceptable hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed. When ordering, please indicate the used hydraulic fluid.
high flow, high performance pumps
are a family of variable displacement,
inline piston units that incorporate the
proven design, quality manufacturing
techniques and operating features of
other Vickers piston pumps, but in a
smaller, lighter package.
The PVH series has been specially
designed to meet the 250 bar (3625 psi)
continuous duty performance
requirements of new generation
equipment designs.
These are efficient , reliable pumps, with
a selection of optional controls for
maximum operational flexibility.
Designed specifically for strenuous
application, they provide the productivity
gains and controllability improvements
desired in earthmoving, construction,
machine tool, plastics, and all other
energy-conscious markets. As with all
Vickers products, these pumps have
been fully laboratory tested and field
proven. Parameters
