Yamada 780133 Polypropylene Manifold for NDP-5
The Yamada 780133 is a genuine Yamada manifold, Polypropylene, used in NDP-5 series air-operated double diaphragm (AODD) pumps. It is the molded or machined passage that routes fluid between the check valves and the pump's suction or discharge port. It has to hold the check valve components in correct alignment while sealing against the operating pressure of the pump.
Genuine Yamada replacement parts are machined and molded to the original factory tolerances, so fit, alignment and seal engagement match the component being replaced. One per pump. Always compare the exact part number against your pump's nameplate before ordering, since Yamada varies internal components by both pump size and body material / elastomer combination.

Frequently Asked Questions
Q: What causes this kind of structural part to need replacement?
Wear from repeated contact with a moving component, corrosion or chemical attack from the pumped fluid, or physical damage from an impact or overtightened fastener during a previous rebuild.
Q: Is this part likely to wear out again soon after replacement?
Not under normal duty. These are structural components rather than flexing wear items, so a correctly torqued, correctly matched replacement typically lasts for the working life of the surrounding assembly barring abrasive or corrosive service.
Q: How do I confirm this is the correct part for my pump?
Match the part number to your pump's nameplate model and suffix, since Yamada varies this component by both pump size and body material across the model range.
Q: Does this part need to match the pump body material?
Yes. Mixing dissimilar materials in the wetted path can cause galvanic corrosion or chemical incompatibility, so match this part to the body material and elastomer combination already on the pump.
