Mf sequence  CZPT Piston Motor CZPT Model for Excavator

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

Description  

Closed circuit
Series twenty
Dimensions: 20, 21, 22, 23, 24, twenty five, 26, 27
Nominal force 210 bars, Greatest pressure 350 bars.
 
The CZPT MF axial piston variable displacement motors, Sequence twenty, are of swash plate construction with variable stream functionality appropriate for hydrostatic transmissions with shut circuit. The flow charge is proportional to the motors pushed pace displacement, which, in switch, is identified by the swash plate angle. The latter is infinitely adjustable among zero and optimum displacement. Stream path is reserved by titling the swash plate to the opposite side of the neutral or zero displacement situation. These units and areas are fit, sort and perform replacements for CZPT-Sundstrand sequence 20 factors.
 
– Suitable for a variety of apps
– Numerous displacements and possibilities accessible
– eight diverse frame dimensions
– Engineered to supply a prolonged services existence and dependability
– Set displacement motor can be operated in possibly path of rotation
– A number of push shaft alternatives and management choices
– Weighty responsibility bearings and shafts
– Very easily serviceable
– Alternative parts also offered
– Direct replacements for CZPT-Sundstrand
Features 
The entire-length shaft with a substantial effective tapered roller bearing arrangement gives a substantial loading ability for external radial forces. Added motors can be built on. The hydro-mechanical servo displacement handle maintains the picked swash plate position and therefore motor displacement.
On release of the handle manage, the swash plate immediately returns to the null placement and the flow turn into zero.
Substantial situation pressures can be archived with no leakage even at the least expensive temperature by using appropriate shaft seals. The servo valve arrangement offers the facility to include function regulators and distant manage technique. Axial piston models are made for straightforward servicing, full dismantling and reassembly can be carried out normal hand instruments, and all factors or sub-assemblies are replaceable.
Servo Displacement Handle (CZPT reaction)
Regular by management deal with on the servo valve, the swash plate can be infinitely varied in the two route with the aid of the servo technique.
The motor displacement ensuing from any handle manage position can be proven using figures (5a – 5c).
The angle of the handle deal with for stroke initiation and for the final situation of the stroke can vary from device to unit in the selection of the tolerance band.
