Details

Replace damaged diaphragms, valves, and o-rings on your Hypro D403 Diaphragm Pump with the replacement parts included in these Hypro D403 Buna (Black) Diaphragm Pump Repair Kits.

If your Hypro D403 is in constant use, it is recommended to replace the diaphragms every 3 months or 500 hours, while the valves and o-rings should be replaced every 6 months or 1000 hours. A good indication that the diaphragms need to be replaced is if you notice a milky grey color in the sight glass. This most likely indicates the diaphragms are torn. Stop running the pump and replace the diaphragms as soon as possible. Running a diaphragm pump with torn diaphragms can cause serious damage to the pump.

Not only can these repair kits be used on the Hypro D403 and D403GRGI Diaphragm Pumps, they also can be used on the Annovi Reverberi AR403-SP Diaphragm Pump.
