Product Description

 

Product Description

A7VO Series
1.Axial plunger variable pump with tilting disc structure for hydrostatic drive in open circuit
2. flow rate is proportional to transmission speed and displacement
3. the stepless change of flow can be realized by adjusting the Angle of rotating inclined disk.
4. two shell drain outlets
5.excellent oil absorption performance
6. low noise level
7.Long service life
8. axial and radial load capacity of the transmission shaft
9. ideal power weight ratio
10. Multiple control areas
11.short control time
12.The pump is driven by a through shaft and can be mounted with a gear pump or less than or equal to the same specification,the axial plunger pump is 100% through shaft driven.
