The pumps are valve-controlled, self-priming Radial Piston Pumps with fixed displacement.
They consist essentially of the housing , eccentric shaft and pump elements , with suction valve , Pressure Valve and piston .
Suction and displacement procedure
The pistons are arranged radially to the eccentric shaft . The hollow piston with the suction valve is guided in a cylinder and pressed onto the eccentric by the spring . The radius of the piston running surface corresponds to the eccentric radius. The cylinder provides sealing against a hemispherical element .
In downward movements of the piston , the working space in the cylinder is enlarged. Due to the resulting negative overpressure, the suction valve plate is raised from the sealing lip. Simultaneously, the connection from the suction chamber to the working chamber is realized by means of a radial groove in the eccentric .
The working chamber is filled with fluid. In upward movements of the piston , the suction valve is closed and the pressure valve is opened. The fluid now flows to the system via the pressure port .
we have the following pumps:
1.Axial Piston Pumps
2.External Gearl Pumps
3.Internal Gear Pumps
5. Vane Pumps
6.Radial Piston Pumps
