Hydraulic pumps help move liquid or air from one place to another. High pressure pumps move the hydraulic fluid throughout the machine to various parts like motor, cylinders, etc. which become pressurized. Flow of the fluid is controlled by valves. The high pressure pumps are essential equipment in various industries. They are specifically designed for commercial, industrial or domestic applications.

Mechanics

Hydraulic fluid in high pressure pumps flows to the motor and returns to the reservoir. Here the fluid is filtered and then re pumped. This path of the fluid is called the hydraulic circuit. There are two types of circuits, an open center circuit and the closed center circuit. In an open circuit the fluid flows continuously and high pressure is not needed for the valves. In closed center circuits full pressure is required to control the valves for variable flow rate.

The pump has to displace fluid from one place to another. The high pressure pumps move water with the action of a piston. The force applied by the pump results in movement of the water.

High pressure pumps have features like timer, multifunction valves, flow rate display, automatic stop function, etc.

Application

The pump is an elementary machine that can generate high level of pressures in a given system. It can generate pressure exceeding 800 psi. The pumps that generate pressure between 3000 psi to 5000 psi are known as high pressure industrial pumps. These types of pumps are used in a variety of applications in industries and our everyday life. The most common application is in water supply and waste management. These pumps are also used in practical applications like pressure cleaning, chemical and oil processing, reverse osmosis, DI water misting, car wash, etc.

Importance

The importance of the high pressure pumps can be judged from the indispensable uses they are put into depending upon the several varieties of such pumps available:

• The centrifugal pump is used in water treatment, food and chemical industry. These pumps are used for movement, loading and elevating liquids in the industries. These pumps are very handy requiring a simple operation and are preferred for industrial application.

• The container pumps are used specifically to move dangerous, highly inflammable and toxic liquids. Container pumps are made of high quality stainless steel to prevent corrosion. They are sturdy and long lasting. They are easy to clean and maintain.

• The drum pumps are used for processing cosmetics, perfumes, food, chemicals, etc. The wastage of liquids is minimal in these pumps; hence, they are used for costly materials like perfumes. They are made of stainless steel or polypropylene. They can also be used for inflammable liquids. 

Summarizing

There is a great variety of high pressure pumps that are used in different kinds of industries everyday.  They also have domestic and commercial applications. They make it easy to do jobs like waste management which are humanly impossible to do. Depending on the area of application a suitable model can be chosen with guidance from the experts in the field.
