Principle of gas-liquid booster pump

Technical support inquiry / 2026-08-20 09:13:09

The working principle of a gas-liquid booster pump is similar to that of a pressure booster, which applies a very low pressure to a large-diameter air driven piston. When this pressure acts on a small area piston, a high pressure is generated. The booster pump can operate continuously through a two position five air control directional valve. The high-pressure plunger controlled by a one-way valve continuously discharges the liquid, and the outlet pressure of the booster pump is related to the air driving pressure. When the pressure between the driving part and the output liquid part reaches equilibrium, the booster pump will stop running and no longer consume air. When the output pressure drops or the air drive pressure increases, the booster pump will automatically start running until it reaches pressure balance again and then stop automatically

The pump adopts a single gas controlled non-equilibrium gas distribution valve to achieve automatic reciprocating motion, and the gas driven part of the pump body is made of aluminum alloy. The liquid receiving part is made of carbon steel or stainless steel according to different processing media, and the complete set of seals for the pump are imported high-quality products, thus ensuring the performance of the gas-liquid booster pump.

The driving pressure of the gas-liquid booster pump is ≤ 8 bar, which can be increased to 640 Mpa. The direction change method of this series of pumps is completely the same as that of the German Magthinking, and the entire pump is made of aluminum alloy and stainless steel. In the gas driven part of the pump, this series requires lubrication type bent pipes to process gas, in order to lubricate the seals and other internal parts.
