Details

These Repair Kits are designed for the Hypro D403 and D403GRGI Diaphragm Pumps, but will also work on the D303 and D303GRGI Diaphragm Pumps. They also can be used on the Annovi Reverberi AR403-SP Diaphragm Pump.

There are multiple kits to choose from: just diaphragms (9910-KIT2423), valves (9910-KIT2388), o-rings (9910-KIT2389), or the complete D403-RK, which includes diaphragms, valves and o-rings.

The D403-RK or KIT2423 kit will fix a D403 pump that has mixed oil in the crank case. You can tell if your oil is mixed because the oil is milky grey in color. If you have mixed, you have a hole in at least one of your diaphragms, so stop using the pump immediately. Using a Hypro Diaphragm Pump with mixed oil for a long period of time will destroy your pump.

Rittenhouse recommends keeping a repair kit on hand if you rely on your Hypro pump for your business.

The D403 is commonly used in Lesco Sprayers, or Lesco Spray Rigs. This is a stock item at Rittenhouse.
