Small size, easy to maintain.
The life period of valve plate is long. It is suitable for the use under higher pressure range.
With water-cooling structure.
Reciprocating pump has large volume of extraction, is mainly used for gas extraction in the aspect of vacuum impregnation, molten steel vacuum process, vacuum distillation, vacuum evaporation, vacuum concentration, vacuum crystallization, vacuum drying, vacuum filtering and vacuum work of concrete.
Reciprocating pump is not suitable for the extraction of corrosive gas or the gas with graininess dusts.
Filter must be installed at the inlet of the pump if there exists dusts in the extracted gas.
