The CZPT PV axial piston variable displacement pumps, Series 20, are of swash plate construction with variable circulation ability appropriate for hydrostatic transmissions with shut circuit. The stream rate is proportional to the pumps driven pace displacement, which, in change, is determined by the swash plate angle. The latter is infinitely adjustable among zero and greatest displacement. Stream path is reserved by titling the swash plate to the reverse facet of the neutral or zero displacement situation. These units and parts are match, form and function replacements for CZPT-Sundstrand series 20 factors.
– Suitable for a assortment of programs

– Set displacement motor can be operated in both direction of rotation
– Several travel shaft choices and manage choices
– Hefty responsibility bearings and shafts
– Simply serviceable
– Substitute elements also obtainable
– Immediate replacements for CZPT-Sundstrand
Attributes of Danfoss CZPT PV pump
The total-duration shaft with a higher successful tapered roller bearing arrangement offers a higher loading capability for exterior radial forces. Extra pumps can be created on. The hydro-mechanical servo displacement control maintains the selected swash plate placement and therefore pump displacement.
Upon release of the handle manage, the swash plate instantly returns to the null situation and the stream turn out to be zero.
Higher situation pressures can be archived without leakage even at the most affordable temperature by using suitable shaft seals. The servo valve arrangement delivers the facility to integrate purpose regulators and remote handle method. Axial piston models are designed for straightforward servicing, comprehensive dismantling and reassembly can be carried out standard hand equipment, and all components or sub-assemblies are replaceable.
Servo Displacement Handle (CZPT response)
Typical by manage deal with on the servo valve, the swash plate can be infinitely assorted in equally directions with the support of the servo method.
The pump displacement resulting from any control deal with position can be recognized utilizing figures.
The angle of the management deal with for stroke initiation and for the ultimate placement of the stroke can range from unit to device in the selection of the tolerance band.
