Pneumatic High Pressure Pumps
High pressure pump, also known as air driven liquid pump, is a versatile pneumatic pump. It can help you efficiently generate high pressure or safely transfer chemicals and liquid gases. And it is widely used in diverse applications, such as hydrostatic test, burst pressure test, hydraulic power station, chemical injection. High-pressure pumps use compressed air as power, without risk of electric sparks and flames, with explosion-proof characteristics, and maximum pressure up to 640MPa. We supply multiple models of pneumatic high pressure pumps to meet your dual demands on pressure and flow.
Working Principle of High Pressure Pumps
High pressure pump has a large piston and a small piston, and uses the area difference between the two pistons to pressurize liquids. That is, when compressed air pushes the large piston to reciprocate, the small piston also reciprocates synchronously, thereby constantly squeezing liquid to boost liquid pressure.
How to Operate High Pressure Pumps
High pressure pump outlet pressure is equal to the driving air pressure multiplied by the pump’s boost ratio which is a fixed value. So the pump outlet pressure is always proportional to the driving air pressure. Therefore, you can easily adjust or set the pump outlet pressure by adjusting air supply pressure.
High Pressure Pump Features
- Pressurize liquid such as water, oil, chemical, liquid gas, emulsion
- Outlet pressure up to 640MPa and pressure adjustable
- Automatically maintain pressure at any preset pressure
- No energy consumption and no heat during pressure holding period
Typical Applications
- Act as hydro test pump or hydraulic test pump in pressure testing.
- Serve as a high pressure hydraulic pump in hydraulic power pack.
- Use as chemical injection pump in chemical injection skid.
- Act as liquid gas pump to transfer or fill liquid gases such as Co2.

High Pressure Pump System
To facilitate your operation, we integrate high pressure pump, control kit and high-pressure fitting into a robust skid to create a high pressure pump system. It is ready to connect, easy to operate and versatile. For example, it can serve as a hydrostatic test system, hydraulic pressure tester, hydraulic power station or chemical injection system.
Frequently Asked Questions
Are high-pressure pumps suitable for chemicals and corrosive liquid?
Yes. If you use our pumps to handle corrosive liquids such as chemicals, DME, Ethylene glycol, please clarify, and we will equip the pump with wetted parts and corrosion resistant seals.
How do I drive high pressure pump outdoors or in situations where there is no air supply?
High pressure pumps can be driven by compressed air or compressed nitrogen. If there is no air supply on site, you can use a 15MPa or 20MPa nitrogen cylinder to drive the pump.
Do high-pressure pumps have any requirements for the medium temperature?
High-pressure pumps are suitable for liquid medium with temperature range of -20°C to +80°C.
