Yamada® NDP-40 series Air Powered Double Diaphragm (AODD) pumps provide a maximum flow rate of 116 gallons per minute. Pumps are available in aluminum, stainless steel (316), Kynar® (PVDF), groundable acetal, and polypropylene construction.
What separates Yamada from the rest of the pack is our air valve technology. Yamada uses a completely non-lubricated main air valve and independent pilot mechanisms to control the air logic.
As compressed air enters the pump, it is directed via the main air valve to one side or the other, depending upon the starting position of the c-spool. As the air enters the chamber, it forces the diaphragm outward. This outward momentum forces liquid out of the discharge ball valve and loads the opposite inlet ball valve. As the diaphragm travels outward, the connected diaphragm on the opposite side is pulling the diaphragm inward.
When it travels a full stroke, it will contact the pilot valve, depressing it and breaking the seal to open an exhaust port.
The open port allows the compressed air to the exhaust from the back side of the air valve. The pressure drop produces a shift of the main air valve. This motion simply repeats on the other side.
