If you need to replace some diaphragms on your equipment, this D19 or AR/D252 diaphragm kit will do the trick. It comes with 2 desmopan diaphragms, 1 accumulator diaphragm, and 4 o-rings for the pump heads. You’ll need both the replacement diaphragms and the o-rings so that your maintenance holds up under pressure.

Hypro/Pentair is no longer distributing the 9910 series of diaphragm pumps and related parts; however, the pumps and repair parts are still available and will now feature factory labeling.

The 9910-KIT1723 (AR43279) is the standard diaphragm repair kit for the Hypro D19 and AR/D252 diaphragm pumps. The kit Includes the piston diaphragms, accumulator diaphragm and the o-rings that seal the pump heads to the main body. 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 D19/D252 is in constant use. We recommend changing the diaphragms every 3 months or 500 hours of use.
