Piston Pumps

High-Pressure Applications, Complex in Design, with Closer Tolerances.

There are two main types of Piston Pumps, the Axial piston pump, and the Radial piston pump. The basic working principle of the piston pump is similar to a typical air cylinder bicycle pump except that in the hydraulic piston pump the pumping mechanism basically consists of a cylinder barrel, positions with shoes, swashplate, shoe plate, shoe plate bias spring, and a port plate. The pump generates an increasing and decreasing volume by a plunger or piston reciprocating in and out of the cylinder barrel (prime mover). The reciprocating action causes the suction of hydraulic oil and discharges it at very high pressure through the outlet port.

Like the gear pump, all piston pumps also have an inlet port and outlet port. The pressure of piston pumps can reach very high pressure and are usually selected for high-pressure applications and occasionally the combination of both pressure and flow rate.  Piston pumps are used in a vast number of applications, especially in heavy-duty industries, like construction equipment, marine, and shipbuilding.
