Metering pump

2019-01-21View Original

Thread Content

I’m asking for the drawings of the metering pump, its internal structure, and the methods for maintenance. Please help, experts

The interior is relatively simple: it consists of a diaphragm, which is controlled hydraulically to enable liquid absorption and discharge; there are check valves at the inlet and outlet. As for maintenance, the common reason for insufficient flow is related to the diaphragm and check valve

There are two types: piston pumps and diaphragm pumps. Which one do you want? :)
