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 stress 210 bars, Optimum stress 350 bars.
 
The CZPT PV axial piston variable displacement pumps, Sequence twenty, are of swash plate design with variable flow functionality appropriate for hydrostatic transmissions with shut circuit. The movement charge is proportional to the pumps driven pace displacement, which, in switch, is determined by the swash plate angle. The latter is infinitely adjustable amongst zero and highest displacement. Movement direction is reserved by titling the swash plate to the opposite side of the neutral or zero displacement position. These models and elements are in shape, type and purpose replacements for CZPT-Sundstrand sequence 20 components.
 
– Suited for a selection of applications
– A number of displacements and possibilities available
– 8 different body dimensions
– Engineered to provide a prolonged support daily life and reliability
– Fixed displacement motor can be operated in possibly path of rotation
– A number of travel shaft possibilities and handle choices
– Heavy duty bearings and shafts
– Very easily serviceable
– Substitute elements also accessible
– Immediate replacements for CZPT-Sundstrand
 
Characteristics of Danfoss CZPT PV pump
The entire-length shaft with a large productive tapered roller bearing arrangement provides a high loading capability for external radial forces. Extra pumps can be developed on. The hydro-mechanical servo displacement handle maintains the selected swash plate position and therefore pump displacement.
Upon release of the manage handle, the swash plate automatically returns to the null placement and the flow turn out to be zero.
Higher situation pressures can be archived without leakage even at the lowest temperature by utilizing suited shaft seals. The servo valve arrangement delivers the facility to include function regulators and remote control technique. Axial piston models are made for straightforward servicing, comprehensive dismantling and reassembly can be carried out standard hand equipment, and all components or sub-assemblies are replaceable.
Servo Displacement Control (CZPT reaction)
Normal by management handle on the servo valve, the swash plate can be infinitely diverse in equally directions with the aid of the servo program.
The pump displacement ensuing from any control handle place can be proven using figures.
The angle of the handle handle for stroke initiation and for the closing position of the stroke can vary from device to device within the range of the tolerance band.
