Yamada NDP-15FPT 1/2 in Polypropylene AODD Pump, PTFE Diaphragms
The Yamada NDP-15FPT is a genuine Yamada NDP-15 series air-operated double diaphragm (AODD) pump, built with a polypropylene pump body and PTFE diaphragms and valve balls. It uses compressed shop air, not electricity, to reciprocate a pair of diaphragms that alternately draw fluid in on one side of the pump and push it out the other, which lets it run dry without damage, self-prime from a lift, and pass moderate solids without stalling.
With a 1/2 in port and up to 13.5 GPM, this pump is sized for light-to-medium duty transfer, dosing and wash-down work. As with any AODD pump, never run it against a fully closed discharge valve for an extended period, and keep the air supply filtered and regulated to protect the air valve.

Frequently Asked Questions
Q: Can it run submerged?
No. Air-operated diaphragm pumps exhaust air through the muffler and are not designed for submerged operation.
Q: What air pressure does it need?
Like all Yamada AODD pumps, it runs on shop air up to 100 psi max inlet pressure. Flow and pressure output scale with the air pressure and volume supplied, within the pump rated maximum.
Q: Can this pump run dry?
Briefly, yes, since it is self-priming, but running dry for an extended period accelerates wear on the diaphragms and check valves. Avoid prolonged dry running whenever possible.
Q: How often should the diaphragms be replaced?
There is no fixed interval. Diaphragms are a wear item that fail from flex fatigue, chemical attack or dry-running, so replace on a schedule that matches your duty cycle and inspect at the first sign of reduced flow or fluid at the muffler.
