The Sauer PV axial piston variable displacement pumps, Series 20, are of swash plate construction with variable circulation functionality ideal for hydrostatic transmissions with shut circuit. The circulation fee is proportional to the pumps pushed speed displacement, which, in flip, is established by the swash plate angle. The latter is infinitely adjustable between zero and maximum displacement. Flow course is reserved by titling the swash plate to the reverse facet of the neutral or zero displacement place. These models and components are suit, type and purpose replacements for Sauer-Sundstrand collection twenty factors.
– Ideal for a variety of apps
– Several displacements and alternatives accessible
– eight diverse frame measurements
– Engineered to provide a long support lifestyle and reliability
– Mounted displacement motor can be operated in either direction of rotation
– Multiple generate shaft choices and manage possibilities
– Hefty duty bearings and shafts
– Very easily serviceable
– Alternative parts also available
– Immediate replacements for Sauer-Sundstrand
Attributes of CZPT Sauer PV pump
The full-length shaft with a substantial efficient tapered roller bearing arrangement provides a substantial loading ability for external radial forces. Further pumps can be constructed on. The hydro-mechanical servo displacement handle maintains the chosen swash plate situation and therefore pump displacement.
On launch of the management handle, the swash plate automatically returns to the null place and the circulation turn into zero.
High situation pressures can be archived without leakage even at the least expensive temperature by using suited shaft seals. The servo valve arrangement delivers the facility to integrate perform regulators and remote handle method. Axial piston units are designed for easy servicing, comprehensive dismantling and reassembly can be carried out CZPT hand instruments, and all parts or sub-assemblies are replaceable.
Servo Displacement Management (Linear reaction)
Standard by handle deal with on the servo valve, the swash plate can be infinitely diverse in equally directions with the support of the servo method.
The pump displacement resulting from any handle deal with position can be set up using figures.
The angle of the handle deal with for stroke initiation and for the ultimate position of the stroke can vary from unit to unit inside of the range of the tolerance band.
