What are Diaphragm Pumps?

A diaphragm pump, which is also sometimes referred to under the alternative name of membrane pump, is a specific type of positive displacement pump. It's made up of various key components, and the most distinctive characteristic of a diaphragm pump is the presence of a rubber, plastic, or Teflon diaphragm, with valves either side, that helps to pump fluid through the system. There are various kinds of diaphragm pumps, including some with sealed diaphragms and others with unsealed diaphragms.

What are Diaphragm Pumps Used for?

Just like many other kinds of liquid transfer pumps and process pumps, diaphragm pumps are primarily used for transferring or moving water and other liquids. They're used in a wide range of industries and environments for dewatering or water removal, but can also be helpful for processes like filling and metering, thanks to their high levels of accuracy and efficiency.
