The AR70 Diaphragm Repair Kit (AR43243) will provide repairs for the diaphragms on your AR70 pump. This kit includes BlueFlex diaphragms* Desmopan (AR43241) and Buna kits (AR43240) 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 AR70 is in constant use. We recommend changing the diaphragms every 3 months or 500 hours of use.
