The Hypro diaphragm repair kit 9910-Kit1725 is used to replace worn or damaged diaphragms on the Hypro D50 diaphragm pump. When the fluid in the oil sight glass turns a milky gray color it means that one (or more) of the diaphragms has ruptured and the fluid to be pumped is mixing with the oil in the crank case. If this happens to your D50, you will need to purchase a diaphragm repair kit: Kit1725 includes 2 Main Diaphragms (Desmopan), 1 Air Chamber Diaphragm (Buna-N), and 4 O-Rings. The O-Rings are used to replace those rings that may have absorbed chemical due to the rupture.
