Yamada 772651 Spacer for DP-10, NDP-15
The Yamada 772651 is a genuine Yamada spacer, used in DP-10, NDP-15 series air-operated double diaphragm (AODD) pumps. It sets the correct working clearance between adjoining components in the pump stack-up. Getting this dimension right on reassembly is what keeps the diaphragm and valve components running true.
Genuine Yamada replacement parts are machined and molded to the original factory tolerances, so fit, alignment and seal engagement match the component being replaced. As required 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: 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.
Q: What should I check before reassembling around this part?
Confirm mating surfaces are clean and undamaged, replace the gaskets or O-rings it seals against rather than reusing them, and torque fasteners to the factory sequence and spec rather than just snugging them down.
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.
