Comet Repair Kit 5026.0245 or 5026.0344.00 contains replacement diaphragms, valves, and o-rings that can be used to replace worn parts on your Comet APS41 Diaphragm Pump. If you see that the oil in your Comet APS41 Pump has turned a milky gray color, stop using the pump and replace your diaphragms immediately. Running a diaphragm pump with broken diaphragms can damage your pump beyond repair. It is better to just order a repair kit as a precaution, opposed to purchasing an entirely new pump.
