Use the AR43320 repair kit to change out the diaphragms on your BHA/BHP/BHS130 & 150 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.

Manufacturer Description:

The Diaphragm Repair Kit (AR43320) will provide repairs for the diaphragms on your pump. This kit includes BlueFlex diaphragms* Desmopan (AR43319) and Buna kits (AR43318) 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 pump is in constant use. We recommend changing the diaphragms every 3 months or 500 hours of use.
