These pumps are primarily used for cleaning and cutting operations. The water from the pump gains energy as it flows out through the discharge nozzle. The kinetic energy of the water is used to perform required operations, such as cleaning and cutting.

The discharge is in the form of a water column. The water jet slammed into the surface like a ton of small, powerful hammers. This helps clean dirt or dust particles. High pressure water jet is one of the most important industrial cutting tools used in the modern world.

High pressure water pump selection

Select high pressure pumps according to the factors that affect the performance and application of the pump.

Pressure - Pressure is used to indicate the kinetic energy that can be transferred to the discharge water. Discharge water is pressurized according to application requirements. For cleaning applications, the water is pressurized to 3,000 psi to 5,000 psi. For cutting applications, they are treated with ultra-high pressure in the pressure range of 30000psi to 50000psi.

Flow - the amount of water pumped in a given period of time. We have to find the flow of the pump to pressurize the water to the desired level. It is expressed in units of volume per unit time and measured in gallons per minute (GPM).

Power supply - We must choose a suitable motor with rated power to pump high pressure water. The rated power of the motor depends on the capacity, flow and pressure range. Power is expressed in horsepower (HP). The pump is powered by an electric, gasoline, pneumatic or hydraulic power source.

Piping and supply lines - Piping and discharge lines must be able to withstand high pressure water flowing through them. Normal pipes cannot withstand these high pressure pumps. The pipeline in the high pressure pump uses a special reinforced high pressure pipeline with three to four layers of wire mesh. The rated pressure of the pipe must be higher than the discharge pressure of the water to remain safe.

Filter system - Typically, the inlet of the pump is fitted with filters to remove unwanted dirt and solid molecules. Dirt or debris can affect pump performance. If mixed with high-pressure water jets at the discharge, they can cause damage to the work surface.

High pressure pump application:

• High pressure pumps are used for cleaning and cutting purposes in a variety of applications in multiple fields.

• They are used in industry; Cleaning, offshore cleaning, floor cleaning and heat exchanger cleaning applications.

• They are used in floor preparation, deburring and concrete refurbishment processes.

• They can be used to clean some inaccessible and hard dirt and oil in our homes.

• They are used for cutting materials such as wood, concrete cutting and various other soft materials. Hard materials can be cut by mixing water with abrasives.

Limitations of high pressure pumps:

• Noisy operation.

• May result in flooding, so appropriate drainage systems must be used.

• Dirt or dirt is splashed by water, causing an environmental mess. They can damage electrical connections. Proper insulation must be provided for electrical connections and power lines before cleaning.
