How does a Diaphragm Pump work?
A diaphragm pump operates by using a flexible diaphragm that moves back and forth to create a variable volume within the pump chamber. As the diaphragm moves up, it creates a vacuum, drawing fluid into the chamber. When the diaphragm moves down, it pushes the fluid out of the discharge valve. This type of pump is often used for its reliability and ability to handle various fluids without contamination, as the fluid does not come into contact with moving parts like gears or pistons.
Types of diaphragm pumps
Our Verderair range consists of two different types of diaphragm pump, air operated double diaphragm pumps, and electrically driven double diaphragm pumps. As their names imply, the key difference between the two would be the way the operate, with the former being driven by compressed air, while the latter is operated using an electric motor.
