Yamada remedies re-piping issues with the Yamada® NDP-32 series pump. Designed to facilitate pump replacement for existing non-Yamada pump installations, the NDP-32 utilizes a 1-1/2" NPT inlet port with a 1-1/4" NPT outlet port to ensure compatibility with competitor designs.

The NDP-32 is available with all Yamada elastomer offerings: Buna N, Hytrel®, Viton®, EPDM, Neoprene®, Santoprene®, and PTFE.

As with all NDP series pumps, the NDP-32 incorporates the same patented Non-Lubricated Air Motor technology and has all the features of the NDP line including bolted design, outside accessible air motor, ease of maintenance, interchangeability of parts, and Yamada reliability.
