Pumps are pieces of equipment or machinery designed to move slurries, liquids or gases. There are a lot of different types of pumps available and different pumps work in different ways. Our double diaphragm pump is reciprocating type, driven by air.

Diaphragm pumps are categorized under the most common types of industrial pumps. It makes use of the so-called positive displacement method in order to move a liquid from one location to another.

The diaphragm pump can be used as drum pump, put the suction pipe into a drum or barrel. The operation is easy. The air diaphragm pump has the function of self priming without rotating parts. It can achieve dry priming and wet priming, which self-priming height is 5m and 8m respectively. Below is a schematic diagram of the installation of the pump.
