Use the AR43251 repair kit to change out the diaphragms on your AR115 & AR135 pump. Diaphragms are the most common wear part on these pumps and if they rupture make sure to change them out immediately. This kit contains diaphragms and o-rings.

The AR115/135 Diaphragm Repair Kit (AR43251) will provide repairs for the diaphragms on your AR115 & AR135 pump. This kit includes BlueFlex diaphragms* Desmopan (AR43249) and Buna kits (AR43248) are also available. If the oil in your diaphragm pump has a milky gray color, you most likely will need to replace the diaphragms. Running a diaphragm pump with oil that is mixed with chemical can cause extensive damage to your pump. Keep this kit handy if your AR115/135 is in constant use. We recommend changing the diaphragms every 3 months or 500 hours of use.
