Hydraulic pumps convert the mechanical energy in motion and fluid power systems and are generally powered by gas or electricity. However, hand and air pumps are also used. There are three main types of pumps used in hydraulic fluid power industry, namely vane pumps, gear pumps and piston pumps. These are all positive displacement pumps, i.e. transfer a calculated quantity of hydraulic fluid pressure in a hydraulic system. This liquid is progressing at the necessary component and its pressure is converted to mechanical power.

A hydraulic pump can be divided into groups. For example, can radial piston pumps, axial, online alternative, folded or AX-axial piston pumps. Vane Pumps are either coming or sliding vane pumps. Subcategorized as the pumps may change for special applications. These pumps have a wide choice of models. Whatever the format, all hydraulic pumps are designed for use with liquid viscosity is determined.

The changes in the viscosity of the liquid ensures that the performance changed, often reducing the effectiveness. Most pumps damaged by solid particles and liquid, and therefore a filter system.

A hydraulic pump is a very important component of construction, fabrication, machining and equipment. It is responsible for a machine precision, efficiency and overall performance of an entire system. Different materials are used in hydraulic pumps to minimize wear and provide consistent performance. The type of material used varies with pressure and temperature of the hydraulic system will be submitted. A number of plastics, synthetic rubber and steel alloys are used in the manufacture of hydraulic pumps. High-strength alloys and polymers are used in pressure systems.

When choosing a pump, it is recommended to consider factors such as operating pressure, temperature and frequency. For applications that require a minimum of pressure, cheaper, low-pressure pumps are available. Some examples of hydraulic pump manufacturers are LIFO Hydraulics, Inc., Flint Hydraulics, Inc HYSECO, Inc. and Crafts Fluid Systems.
