20 Series Danfoss PV21 PV22 PV23 PV24 Hydraulic Piston Pump
Sauer Danfoss PV21 PV22 PV23 Hydraulic Piston Pump For Mixers
General Description
Axial piston variable displacement pumps, Series 20, are of swash plates construction with variable flow capability suitable for hydrostatic transmission with closed loop circuit.
The Flow rate is proportional to the pump´s driven speed and displacement, which, in turn, is determined by the swash plate angle. The latter infinitely adjustable between zero and maximum displacement.
Flow direction is reversed by tilting the swash plate to the opposite side of the neutral or zero displacement position.
Features:
Axial piston variable displacement pumps, Series 20, are well-engineered and easy to handle.
The full-length shaft with a high efficient tapered roller bearing arrangement offers a high loading capacity for external radial forces.
Additional pumps can be built on.
The hydro-mechanical servo displacement control maintains the selected swash plate position and hence pump displacement.
Upon release of the control handle, the swash plate automatically returns to the null position and the flow become zero.
High case pressures can be archived without leakage even at the lowest temperature by using suitable shaft seals.
The servo valve arrangement offers the facility to incorporate function regulators and remote control system.
Axial piston units are designed for easy servicing, complete dismantling and reassembly can be carried out standard hand tools, and all components or sub-assemblies are replaceable.
