The gas booster pump series is a single-stage booster pump. In order to reach the required pressure gas input port, the pressure input needs to be preloaded to a certain degree. The preloading pressure varies with the maximum pressure achieved. Up to 80Mpa. This series pump commutation is identical with series B, the difference is that the series pump is a double head pump based on series B, the whole pump is made of aluminum alloy and stainless steel. The driving piston diameter of the series pumps is 160mm, and the driving pressure is no more than 8bar. Both ends of the pump head with exhaust cooling, when leaving the factory, two inlet and two outlet can be well connected according to user requirements.
