The booster pump uses the area ratio of large and small pistons to generate a pressure ratio to pressurize gas or liquid. To be specific, the booster pump consists of an air driving section with a large piston inside and a high pressure section with a small piston inside. And the two pistons are connected by a shaft. Under the control of pneumatic shuttle valve, the compressed air drives the large piston to reciprocate, so the small piston reciprocates synchronously.
The gas or liquid entering the high-pressure section is continuously squeezed by the small piston. According to Pascal’s law, the driving air pressure multiplied by the large piston area is equal to the pressure inside high-pressure section multiplied by the the small piston area. In this way, the gas or liquid entering the booster pump will obtain a higher pressure and then be discharged.To ensure that the gas or liquid does not leak prematurely during the pressurization process in the high-pressure section, the booster pump is also equipped with an inlet check-valve and an outlet check-valve.
Depending on the medium, booster pumps can be divided into gas booster pumps and high-pressure pumps. The gas booster pump, as know as high pressure gas pump, can safely boost various gases up to 1600bar. The high pressure pump, also known as air driven liquid pump, can boost water or other liquids to 6400bar maximum.
