CZPT CZPT-Sundstrand axial piston pump PV20, PV21, PV22, PV23, PV24, PV25, PV26, PV27

Description  

Shut circuit
Series twenty
Dimensions: twenty, 21, 22, 23, 24, twenty five, 26, 27
Nominal pressure 210 bars, Optimum strain 350 bars.

 
The CZPT PV axial piston variable displacement pumps, Sequence twenty, are of swash plate building with variable movement functionality appropriate for hydrostatic transmissions with closed circuit. The circulation charge is proportional to the pumps driven speed displacement, which, in turn, is identified by the swash plate angle. The latter is infinitely adjustable between zero and greatest displacement. Flow direction is reserved by titling the swash plate to the opposite side of the neutral or zero displacement place. These units and components are fit, type and perform replacements for CZPT-Sundstrand series twenty parts.
 
– Suitable for a assortment of purposes
– A number of displacements and choices available
– 8 diverse body dimensions
– Engineered to offer a prolonged provider existence and dependability
– Fixed displacement motor can be operated in possibly route of rotation
– Multiple push shaft possibilities and control choices
– Hefty responsibility bearings and shafts
– Simply serviceable
– Replacement elements also offered
– Direct replacements for CZPT-Sundstrand
 
Features of Danfoss CZPT PV pump
The full-length shaft with a substantial effective tapered roller bearing arrangement gives a substantial loading capability for exterior radial forces. Additional pumps can be built on. The hydro-mechanical servo displacement manage maintains the selected swash plate place and hence pump displacement.
On release of the manage take care of, the swash plate routinely returns to the null place and the stream turn out to be zero.
High scenario pressures can be archived without having leakage even at the lowest temperature by making use of suited shaft seals. The servo valve arrangement delivers the facility to incorporate operate regulators and remote control program. Axial piston models are made for effortless servicing, full dismantling and reassembly can be carried out normal hand instruments, and all factors or sub-assemblies are replaceable.
Servo Displacement Handle (CZPT reaction)
Regular by manage handle on the servo valve, the swash plate can be infinitely assorted in each instructions with the aid of the servo program.
The pump displacement resulting from any manage handle position can be proven employing figures.
The angle of the control deal with for stroke initiation and for the final placement of the stroke can vary from unit to device inside of the variety of the tolerance band.
