TECHNICAL UPDATE
Dimension changes NDP and AD-25 PVDF series
After many years, Yamada Corporation needed to create new moldings for the NDP and AD-25 series to replace the old ones. With that they also took the advantage making some small measurement changes on the NDP-(P)25BV. series, providing the highest quality required these days. The adaption of measurements will not have any negative effect on the total pump performance. Maximum flow, suction performance and others will remain the same. What measurements will change? Pump chamber, manifold, ball guide, ball seat and outer center disk. As a result, some outer measurements of the following pumps and dampener will change as follows; NDP-25BV.(-FLG) PVDF pump with aluminum anodic coated motor:
NDP-P25BV.(-FLG) PVDF pump with PP motor
AD-25V. Pulsation dampener

Which parts are going to change?
Are parts interchangeable? Not all. New pump chambers (9), ball guides (2) and valve seats (4) are not interchangeable as separate parts on the old models. As a complete set, they are interchangeable.
Availability old spare parts; Until the end of 2019 we can supply the old articles as described in the table at the beginning of this page. After that only the new parts are available. We recommend to upgrade your old pump asap
Spare part kits old pump model and new pump model: Only the valve kit of the new pump models will become a temporary article code until the old spare parts run out (end of 2019). After that the temporary code will stop, and it will be replaced by the old well known codes. This kit will contain the new ball guides and valve seats and is as a result no longer interchangeable with the old pump model. Around that time you will be informed. See page 3 for these kits.
