Bring your Hypro D252 or D252GRGI Diaphragm Pump back to life by replacing any damaged diaphragms and valves with the replacement parts included in the Rittenhouse Hypro D252 Desmopan Diaphragm and Valve Complete Repair Kit (D252REPAIRDESMO).
This repair kit is basically a combination of the diaphragm and valve repair kit for the Hypro D252 Diaphragm Pump (9910-KIT1723 and 9910-KIT2408).
You will know when it's time to replace the diaphragms if you notice a milky grey color in the sight glass of the pump. This usually means one or more of the diaphragms have torn and need replacing. Do not run the pump or you run the risk of causing serious damage to the pump. It is recommended, if your pump is in constant use, to replace diaphragms every 3 months or 500 hours and replace valves every 6 months or 1000 hours to keep it performing up to standards all season long.
