Description  

Closed circuit
Sequence 20
Dimensions: 20, 21, 22, 23, 24, twenty five, 26, 27
Nominal pressure 210 bars, Greatest force 350 bars.
 
The CZPT PV axial piston variable displacement pumps, Series twenty, are of swash plate development with variable flow ability ideal for hydrostatic transmissions with closed circuit. The stream charge is proportional to the pumps driven pace displacement, which, in change, is decided by the swash plate angle. The latter is infinitely adjustable in between zero and highest displacement. Stream path is reserved by titling the swash plate to the reverse side of the neutral or zero displacement placement. These units and areas are fit, kind and purpose replacements for CZPT-Sundstrand sequence twenty elements.
 
– Appropriate for a range of programs
– Multiple displacements and options accessible
– eight various frame measurements
– Engineered to give a lengthy services daily life and dependability
– Set displacement motor can be operated in possibly direction of rotation
– Several push shaft alternatives and handle alternatives
– Heavy responsibility bearings and shafts
– Effortlessly serviceable
– Alternative areas also obtainable
– Immediate replacements for CZPT-Sundstrand
 
Characteristics of Danfoss CZPT PV pump
The complete-length shaft with a large successful tapered roller bearing arrangement offers a substantial loading potential for exterior radial forces. Additional pumps can be built on. The hydro-mechanical servo displacement handle maintains the selected swash plate placement and consequently pump displacement.
On release of the handle manage, the swash plate immediately returns to the null place and the stream turn into zero.
Higher scenario pressures can be archived with no leakage even at the lowest temperature by employing appropriate shaft seals. The servo valve arrangement gives the facility to incorporate perform regulators and remote control program. Axial piston models are developed for effortless servicing, comprehensive dismantling and reassembly can be carried out common hand instruments, and all elements or sub-assemblies are replaceable.
Servo Displacement Manage (CZPT response)
Regular by control handle on the servo valve, the swash plate can be infinitely diverse in equally instructions with the help of the servo method.
The pump displacement resulting from any management handle place can be set up employing figures.
The angle of the handle manage for stroke initiation and for the final position of the stroke can vary from device to unit in the range of the tolerance band.
