Yamada 771235 Pump Base, polypropylene for NDP-25
The Yamada 771235 is a factory pump base used in NDP-25 Series pumps with polypropylene wet ends. A diaphragm pump shakes as it runs, and the mounting parts take that vibration continuously.
Rubber feet are cheap and do a real job. They isolate the pump from the structure, cut transmitted noise, and stop the fasteners from working loose through vibration. Hardened, split or missing feet are worth replacing as a set.

Frequently Asked Questions
Q: My pump walks when it runs. What should I check?
The mounting feet and the hold down fasteners first. A pump that is not firmly located puts cyclic load into the manifold connections, which is where the leaks start.
Q: Why has the base corroded so badly?
It usually sits lowest, so it is in contact with whatever water collects around the installation. On marine duty it is normal for the base to need attention before anything internal does.
Q: Should the feet be replaced as a set?
Yes. Mixing new and hardened feet leaves the pump sitting unevenly and concentrates the vibration on the tired ones.
Q: Does the base need to match the wet end material?
It should match the model and the build. Yamada supplies bases to suit metal and plastic wet ends separately because the fixings and loads differ.
