If the diaphragms on your Hypro D252 or D252GRGI Diaphragm Pump need to be replaced, you can rely on the Hypro D252 BlueFlex Diaphragm Repair Kit (9910-KIT1723BLUE) to get the job done.
This repair kit includes the new BlueFlex diaphragms, which redefine durability in diaphragms, even in the toughest of working conditions. Perfect for handling liquid fertilizers, weed killers, pesticides, fungicides, and other liquids and aggressive chemicals, the BlueFlex diaphragm uses some of the best diaphragm material available. The shape and thickness of the BlueFlex diaphragm have been carefully optimized for reducing mechanical stresses during the working cycle of the pump, even under harsh working conditions.
You most likely need to replace the diaphragms if you see the oil in the sight glass is milky grey in color. Replace the diaphragms as soon as possible because running your pump with torn diaphragms can cause serious damage to the pump.
