Replace damaged diaphragms on the Hypro D403 Diaphragm Pump with the replacement parts included in this Hypro 9910-KIT2423BUNA Diaphragm Repair Kit.
If you notice a milky grey color in the oil sight glass, this most likely indicates the diaphragms are damaged and need to be replaced. Stop running your pump and replace the diaphragms immediately. Running your diaphragm pump with torn diaphragms can cause serious damage to your pump. If your pump is in constant use, it is recommended to replace the diaphragms every 3 months or every 500 hours to ensure your pump remains reliable in the field.
