AR43283 Desmopan Seal Kit

The AR30 & AR40 Diaphragm Repair Kit (AR43283) will provide repairs for the diaphragms on your AR30/40 pump. This kit includes Desmopan diaphragms* BlueFlex (AR43285) and Buna kits (AR43282) 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 AR30/40 is in constant use. We recommend changing the diaphragms every 3 months or 500 hours of use.
