CZPT A4VG28/A4VG45/A4VG50/A4VG56/A4VG71/A4VG125/A4VG180/A4VG250 Axial Piston Variable CZPT Pump

Characteristics:

one.type axial plunger variable pump for closed circuit hydrostatic generate
2.The stream price is proportional to the driving pace and displacement and can be variable without having grade
3.The circulation rate boosts from zero to its optimum with the Angle of inclined disk
four.The flow course of the liquid flow can be transformed smoothly by creating the inclined disk swing by means of the center situation
5.A variety of variable modes that are easy to match with a variety of management and regulation programs
six.The inlet pump is geared up with two overflow valves on the substantial-strain oil facet to safeguard the static hydraulic push (pump and motor) from overload
seven.The substantial-pressure overflow valve of the inlet also has the perform of filling oil valve
8.The inside auxiliary pump is utilised as the refill pump and management pump
9.The maximum oil refill strain is minimal by a built-in oil refill overflow valve
10.Complete sequence with created-in force shutoff valves
11.Nominal stress four hundred bar,Peak strain 450

 

Manage mode:

NV kind, no manage device
DG- hydraulic control, immediate control kind
Ez-electrical two-position handle with switching electromagnet
Hd-hydraulic handle, related to pilot force
HW- hydraulic control, mechanical servo
EP- electrical manage with proportional electromagnet
DA- hydraulic control, connected to deceleration
