MouldAir air operated double diaphragm pumps (AODD pumps) are designed for general fluid transfer. Our diaphragm pumps reliably transfer a wide variety of fluids, from clean, light viscosity to medium viscosity. They can pump large particles without damage.
Metal or plastic diaphragm pump casings can easily handle corrosive and abrasive fluids. Most MouldAir diaphragm pumps are ATEX certified(CE Ex11 2GD X).

Rugged and Reliable in Harsh Conditions

MouldAir diaphragm pumps are expertly engineered to go the distance, even in the harshest environment.

Our pumps feature maximized flow rates with minimized pulsation and air consumption. Our patented unbalanced air valve design ensures stall-free, ice-free operation. Due to their pneumatic motor, our diaphragm pumps could be used in potentially explosive areas.

MouldAir diaphragm pumps are a reliable, cost-effective choice for industrial and chemical applications. Our bolted, leak-free construction eliminates cross-contamination and increases operator safety. Modular construction, reduced parts count and easy-to-use repair kits minimize repair time and cost.

Our pumps are rigorously tested — far beyond typical industrial use — to ensure that your MouldAir diaphragm pump is built to last.

Diaphragm Pumps Tailored to Your Application

MouldAir diaphragm pumps are available with many flow rates and sizes, allowing you to vary the flow outlet and discharge pressure. Our pumps can run as slow as 0.26 gallons (1 liter) per minute and up to 275 gallons (1079 liters) per minute for larger pump sizes. Adjust fluid pressure up to 125 p.si. (8.6 bar) by using an air filter/regulator and a needle valve.

Each MouldAir diaphragm pump can be customized for your fluid transfer needs. Choose from a wide range of diaphragm materials, casing options and accessories. Find metal or plastic fluid sections and housings that can handle any fluid, including corrosives and abrasive.
