Frequently asked questions
Will the pump be damaged if it runs dry?
No. Air-operated diaphragm pumps do not heat up when running idle, and since there is no friction, they do not wear.
What happens when the discharge valve closes?
The pump slows down and stops without consuming energy. When the valve opens, it resumes pumping automatically.
How do I adjust the flow rate?
By changing the air inlet pressure and volume. The performance curves in the catalogue show the flow rate against air pressure.
Ball valve or flap valve?
Ball valves for viscous fluids and small solids. Flap valves for solids close to the pipe diameter.
Can it be used in explosive atmospheres?
Since there is no motor or electrical connection, it is used in explosive atmospheres, underground mines and chemical plants.
How can I increase capacity?
Multiple diaphragm pumps can be connected in parallel at the outlet.
