CZPT Mf20/21/22 CZPT Piston Motor  for CZPT 

CZPT CZPT-Sundstrand axial piston motor MF20, MF21, MF22, MF23, MF24, MF25, MF26, MF27

Description  

Closed circuit
Collection 20
Measurement: 20, 21, 22, 23, 24, 25, 26, 27
Nominal stress 210 bars, Maximum pressure 350 bars.
 
The CZPT MF axial piston variable displacement motors, Series twenty, are of swash plate construction with variable movement functionality suitable for hydrostatic transmissions with closed circuit. The circulation fee is proportional to the motors driven speed displacement, which, in switch, is decided by the swash plate angle. The latter is infinitely adjustable between zero and optimum displacement. Stream course is reserved by titling the swash plate to the reverse facet of the neutral or zero displacement placement. These units and parts are in shape, form and perform replacements for CZPT-Sundstrand sequence 20 parts.
 
– Appropriate for a range of purposes
– Multiple displacements and possibilities accessible
– eight diverse body measurements
– Engineered to provide a extended service daily life and trustworthiness
– Fastened displacement motor can be operated in both route of rotation
– Multiple generate shaft possibilities and control options
– Hefty duty bearings and shafts
– Effortlessly serviceable
– Substitute parts also available
– Direct replacements for CZPT-Sundstrand
Features 
The complete-size shaft with a high effective tapered roller bearing arrangement offers a large loading capability for exterior radial forces. Further motors can be developed on. The hydro-mechanical servo displacement management maintains the selected swash plate position and hence motor displacement.
On release of the management manage, the swash plate routinely returns to the null situation and the stream turn into zero.
Large case pressures can be archived without having leakage even at the cheapest temperature by using ideal shaft seals. The servo valve arrangement offers the facility to include function regulators and remote manage system. Axial piston units are developed for easy servicing, total dismantling and reassembly can be carried out regular hand equipment, and all components or sub-assemblies are replaceable.
Servo Displacement Manage (CZPT reaction)
Normal by handle handle on the servo valve, the swash plate can be infinitely assorted in both path with the help of the servo technique.
The motor displacement resulting from any manage deal with position can be proven using figures (5a – 5c).
The angle of the manage manage for stroke initiation and for the final place of the stroke can range from unit to unit within the assortment of the tolerance band.
