Duplomatic axial piston pumps can be made to vary their displacement, or swept volume, by altering the angle of the swash plate against which the pistons operate. The pump's variable output flow can be controlled by a number of different criteria such as pressure signals which are fed back to the swash plate control. Typical applications are open loop drives where a stand by condition is required.

ADVANTAGES
OPEN CIRCUIT - VARIABLE DISPLACEMENT
Pumps are variable swash plate design for open circuit applications & are supplied with ISO two bolt mounting flanges & SAE flanged ports.
PRESSURE AND ELECTRICAL CONTROLLERS
Eight different regulating controls including Pressure Compensated with & without minimum settings, Pressure / Flow Regulators, Proportional Pressure & Flow Control, Power Regulator etc.
ADDITIONAL POWER TAKE OFF MOUNTING
All pumps are available with an SAE A, B or C rear flange, that can be used for mounting additional services pump.
MULTIPLE VERSIONS AVAILABLE
Units can be coupled together for tandem circuit drives with full power outputs from both pumps.

Temperature
Oil temperature should be between +30ºC & +60ºC during normal operation. Oil life is greatly reduced if temperature exceeds 60ºC. As a general rule, oil life is halved for each 8ºC temperature exceeds 60ºC.
Filtering
It is necessary to keep the level of contamination within a hydraulic system at an acceptable level to ensure trouble free operation. Filtration should always be specified at a level that protects the most sensitive item or component in the system. |
