In the industrial field, high pressure pumps are used on a daily basis in a variety of environments. From heavy construction to agriculture, these units are designed to take a liquid material under low pressure and return it as a liquid material under high pressure. While there are many ways by which the machines can do this, the use of a hydraulic system is one of the most common. High pressure hydraulic pumps have several benefits that can not only improve efficiency, but also reduce cost and maintenance time.
What Is A Hydraulic Pump?
A hydraulic pump is a machine component that utilizes the energy created by fluid movement as a power source. They can be either hydrodynamic or hydrostatic.
With a hydrostatic pump, the displacement effect is considered a positive one. The pump operates by drawing liquid into a section of the pump until the area if full, and then forcing it out the other end. As the liquid is forced out, the open area begins to fill again.
Hydrodynamic pumps can, in turn, be either fixed or variable displacement pumps. A fixed displacement pump is created with a predetermined displacement amount that cannot be adjusted. They are designed for use in specific areas where variability is not necessarily of functional importance. For more general uses, a variable displacement pup can be used. This design allows the user to control how much or how little liquid is displaced during the operating process, thereby controlling the volume and pressure of the flow being expelled.
The primary differentiator among high pressure hydraulic pumps is done on a psi rating scale. The psi rating given to a particular unit indicates the pounds per square inch or pressure the pump is able to produce. Residential applications typically require very low psi ratings while industrial use demands a much higher pressure capability.
Some pumps are designed specifically for clean water or liquid handling only as they are not capable of processing any particulate matter. Others are created especially for environments where the liquid being run through the pump contains a significant amount of sand, debris, or other materials that typically need to be filtered out during the pumping process or, in some cases, allowed to pass through.
What Are High Pressure Hydraulic Pumps Used For?
Hydraulic pumps can be used to power a variety of high pressure devices. For residential use, smaller pumps can be used for light duty pressure washing. In the commercial area, pumps can sometimes be found powering brushless car washes. The industrial sector, however, offers the widest use of high pressure pumps with applications such as offshore oil drilling and mining. Hydraulic pumps act as components for a range of tools including torque machinery, tunneling equipment, and hydraulic presses.
