The piston compressor is a type of positive displacement compressor. Due to its characteristics such as wide ranges of discharge pressure and displacement, and high volumetric efficiency, it is widely used in many industries including petrochemical, silicon and fluorine chemical, hydrogen production, and metallurgy. For piston compressor models, the piston force ranges from 25 to 800KN, the maximum pressure can reach 25 MPa, and the rotational speed ranges from 300 to 1000rpm. There are various models such as M, D, L, and P types, more than 60 product series. The number of compressor stages can achieve pressure matching from one stage to six stages. The products comply with the API 618 standard and fully cover market demands.
