YAMADA® NDP-80 Series Double Diaphragm Pump
$2,500.00 – $11,900.00
Yamada® NDP-80 series Aodd pumps provide a maximum flow rate of 215 gallons per minute.
This is currently the largest pump available in the Yamada® range.
This is a high performance process pump and is popular in many industries for transferring high volume fluids. It has many features and is available in a large range of materials. Port size 3″(80mm) maximum discharge volume of 840L/min.
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.
