A hydraulic pump works by using mechanical energy to pressurize fluid within a closed system. The pressurized fluid is then used to power machinery like excavators, presses, and lifts.
There are two main types of hydraulic piston pumps: axial and radial. Both types can be fixed or variable displacement. A fixed displacement pump moves a set amount of fluid each cycle, while a variable displacement pump can adjust the amount of fluid moved per cycle.
Choosing the right hydraulic pump depends on an assessment of your application. Consider the required pressure, flow rate, speed, horsepower, and the type of fluid used. Radial piston pumps can handle a variety of fluids, including mineral oil and water-glycol hydraulic fluids, while axial piston pumps are preferred for high-pressure applications.
Compared to gear pumps and vane pumps, piston pumps offer distinct advantages:
Overall, piston pumps stand out for their high pressure, compact structure, efficiency, and ease of flow adjustment, making them widely used in high-pressure, high-flow applications such as hydraulic presses, construction machinery, and marine equipment.
