Comet MC25 Diaphragm Pump, Parts & Kits
If you rely on a Comet MC25 diaphragm pump for spraying or chemical application, having the right spares on hand from QSpray can save you a lot of downtime and money. At QSpray.com, we stock a comprehensive selection of Comet MC25 DS pump parts, from basic valve and diaphragm assemblies to complete rebuild kits, so you’re never left mid-job waiting for a replacement.
The MC25 is a twin diaphragm, semi-hydraulic pump built with an anodized aluminum body, capable of pressures up to 362 PSI and a flow rate around 6 GPM, making it ideal for landscaping, pest control, lawn care, and other demanding spraying applications.
Over time, Comet MC25 pump parts, including diaphragms, valves, O-rings, and other components, can wear down. Running the pump past its prime diaphragms can lead to leaks, poor pressure, or even damage. That’s why we offer the trusted Comet 5026.0347 MC25 Pump Repair Kit, which includes diaphragms, accumulator diaphragm, valve assemblies, and O-rings to restore pump performance quickly.
For heavier maintenance needs, the more complete Comet 5026.0116DS kit gives you everything from diaphragm and valve assemblies to gaskets, oil caps, and more.
By keeping these parts and kits in stock, you can ensure your pump stays reliable and ready, whether you’re spraying lawns, treating crops, or handling herbicides and pesticides.
