Use the AR43318 Buna 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.

The Diaphragm Repair Kit (AR43318) provides repairs for the diaphragms on your pump. This kit includes Buna 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 need to replace the diaphragms. Running a diaphragm pump with oil mixed with chemical can cause extensive damage to the pump. Keep this kit handy if your pump is in constant use. It is recommended to change the diaphragms every 3 months or 500 hours of use.
