Description

Yamada pump replacement part that fits our 2" Yamada Diaphragm Pump which includes replacement balls, diaphragms and seals.

We only sell the Buna-N materials of this replacement kit which is a great material for the sealcoating industry because it holds up well to coal tar, asphalt emulsions and most importantly aggregates like sand.

The repair video shows the tear down for the NDP-40BA model, however the 40BA and 50BA are very similar in design and should have similar tear down techniques.

Material

We sell the "Buna-N" material in this replacement kit which we've found to do a great job with asphalt emulsion and coal tar sealers, and the Buna N holds up great with sealers that have abbrasives.
