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

Description  

Closed circuit
Sequence twenty
Measurement: twenty, 21, 22, 23, 24, twenty five, 26, 27
Nominal strain 210 bars, Optimum force 350 bars.
 
The CZPT PV axial piston variable displacement pumps, Series 20, are of swash plate construction with variable circulation capacity appropriate for hydrostatic transmissions with shut circuit. The stream price is proportional to the pumps pushed pace displacement, which, in flip, is established by the swash plate angle. The latter is infinitely adjustable in between zero and optimum displacement. Flow direction is reserved by titling the swash plate to the opposite side of the neutral or zero displacement placement. These units and areas are suit, sort and purpose replacements for CZPT-Sundstrand series 20 parts.
 
– Suitable for a variety of programs
– Multiple displacements and options offered
– 8 diverse body dimensions
– Engineered to give a extended provider lifestyle and dependability
– Mounted displacement motor can be operated in both route of rotation
– Multiple push shaft possibilities and management options
– Hefty duty bearings and shafts
– Simply serviceable
– Replacement elements also offered
– Immediate replacements for CZPT-Sundstrand
