When you need to repair your Comet MP20 or MP30 Diaphragm Pump, make sure you have this 5026.0080 MP20/30 Diaphragm & Valve Kit on hand. This product includes all the parts you need to swap out damaged or faulty pieces, including one accumulator diaphragm, two flat gaskets, nine O-rings, two piston diaphragms and four valve assemblies.

Manufacturer Description:

Comet Repair Kit 5026.0080 contains replacement diaphragms, valves, and o-rings that can be used to replace worn parts on your Comet MP20 and MP30 Diaphragm Pump. If you see that the oil in your Comet MP20/30 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.
