The Hypro diaphragm repair kit 9910-Kit1724 is used to replace worn or damaged diaphragms on the Hypro D30 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 D30, you will need to purchase a diaphragm repair kit: Kit1724 includes 2 Main Diaphragms (Desmopan), 1 Accumulator 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.
