Description  

Closed circuit
Series twenty
Size: twenty, 21, 22, 23, 24, twenty five, 26, 27
Nominal pressure 210 bars, Optimum stress 350 bars.

 
The CZPT PV axial piston variable displacement pumps, Series twenty, are of swash plate building with variable circulation capacity suitable for hydrostatic transmissions with shut circuit. The circulation charge is proportional to the pumps driven velocity displacement, which, in turn, is established by the swash plate angle. The latter is infinitely adjustable in between zero and highest displacement. Circulation course is reserved by titling the swash plate to the reverse aspect of the neutral or zero displacement place. These units and components are suit, sort and perform replacements for CZPT-Sundstrand sequence twenty parts.
 
– Ideal for a range of apps

– 8 distinct frame sizes
– Engineered to supply a extended support existence and reliability
– Set displacement motor can be operated in possibly route of rotation
– Multiple generate shaft alternatives and control options
– Heavy duty bearings and shafts
– Easily serviceable
– Alternative components also accessible
– Direct replacements for CZPT-Sundstrand
 
Attributes of Danfoss CZPT PV pump
The total-length shaft with a higher effective tapered roller bearing arrangement delivers a substantial loading potential for exterior radial forces. Further pumps can be developed on. The hydro-mechanical servo displacement control maintains the selected swash plate situation and consequently pump displacement.
Upon launch of the management manage, the swash plate immediately returns to the null placement and the flow turn out to be zero.
Higher case pressures can be archived without leakage even at the least expensive temperature by utilizing suitable shaft seals. The servo valve arrangement offers the facility to incorporate function regulators and distant control method. Axial piston models are developed for effortless servicing, full dismantling and reassembly can be carried out regular hand resources, and all parts or sub-assemblies are replaceable.
Servo Displacement Management (CZPT reaction)
Standard by handle handle on the servo valve, the swash plate can be infinitely different in each instructions with the assist of the servo method.
The pump displacement ensuing from any management take care of place can be set up employing figures.
The angle of the control manage for stroke initiation and for the closing position of the stroke can fluctuate from device to unit inside of the assortment of the tolerance band.
