Product Description

Hydraulic pumps of type PV7...A are Direct Operated Vane Pumps with adjustable displacement.
They basically comprise of housing, cover, rotor, vanes, stator ring, compression spring , set screw and control plate .
For limitation of the maximum flow, the pump is equipped with a set screw .
The driven rotor rotates within the stator ring . The centrifugal force presses the vanes uided in the rotor against the internal sliding surfaces of the stator ring .

Pumps are as following :

1.Axial Piston Pumps
2.External Gearl Pumps
3.Internal Gear Pumps
4.Gerotor Pumps
5.Vane Pumps
6.Radial Piston Pumps
7.Electrohydraulic pumps
If you have any inquiry please feel free to let me know .

Suction and displacement procedure
The cells necessary to transport the hydraulic fluid are formed by the vanes , the rotor , the stator , the control plate and the cover .
The cell volume increases by the rotation of the rotor and via the suction channel , the cells are filled with hydraulic fluid. When the largest cell volume is achieved, the cells are separated from the suction side.
If the rotor is rotated further, connection to the pressure side is established, the cells narrow and displace the hydraulic fluid via the pressure channel (P) into the system.

Pressure control
The stator ring is held in the eccentric initial position by the spring . The maximum operating pressure required in the system is set at the set screw using the spring .
The pressure building up by the load resistance acts at the pressure side on the inner sliding surface of the stator ring , against the force of the spring .
If the pressure corresponding to the set spring force has been reached, the stator ring is pushed out of its eccentricity in zero position direction. The flow settles at the set value which is just removed. If the peak pressure set at the spring is reached, the pump controls the flow to almost zero. The operating pressure is maintained and only the leakage is replaced. In this way, the power loss and heating of the hydraulic fluid are kept to a minimum.
