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

Description  

Shut circuit
Sequence twenty
Dimension: twenty, 21, 22, 23, 24, 25, 26, 27
Nominal stress 210 bars, Greatest strain 350 bars.

 
The CZPT PV axial piston variable displacement pumps, Sequence 20, are of swash plate building with variable movement capacity suited for hydrostatic transmissions with closed circuit. The flow charge is proportional to the pumps pushed speed displacement, which, in change, is established by the swash plate angle. The latter is infinitely adjustable in between zero and optimum displacement. Circulation route is reserved by titling the swash plate to the reverse facet of the neutral or zero displacement placement. These models and elements are suit, kind and perform replacements for CZPT-Sundstrand sequence twenty factors.
 
– Suitable for a selection of programs
– Several displacements and alternatives offered
– eight different body sizes
– Engineered to offer a prolonged support existence and dependability
– Set displacement motor can be operated in either route of rotation
– Several push shaft options and control alternatives
– Hefty obligation bearings and shafts
– Very easily serviceable
– Substitution areas also obtainable
– Direct replacements for CZPT-Sundstrand
 
Attributes of Danfoss CZPT PV pump
The complete-length shaft with a substantial productive tapered roller bearing arrangement offers a high loading capability for exterior radial forces. Further pumps can be developed on. The hydro-mechanical servo displacement management maintains the selected swash plate placement and hence pump displacement.
On release of the handle handle, the swash plate immediately returns to the null placement and the circulation turn into zero.
Large case pressures can be archived without having leakage even at the most affordable temperature by using suitable shaft seals. The servo valve arrangement delivers the facility to include purpose regulators and remote control program. Axial piston units are created for simple servicing, full dismantling and reassembly can be carried out standard hand tools, and all factors or sub-assemblies are replaceable.
Servo Displacement Handle (CZPT reaction)
Typical by control handle on the servo valve, the swash plate can be infinitely varied in both instructions with the support of the servo program.
The pump displacement ensuing from any manage handle position can be established employing figures.
The angle of the management handle for stroke initiation and for the last placement of the stroke can range from unit to unit inside of the assortment of the tolerance band.
