Comet diaphragm pumps are built for professional spray rigs. Made in Italy by one of the world's leading pump manufacturers, they deliver steady pressure and flow for pest control, lawn care, tree spraying and landscaping applications. Because the diaphragms keep the chemical away from the pump's moving parts, Comet pumps hold up well to the insecticides, herbicides and fertilizers used every day in the field.

Shop our selection of Comet diaphragm pumps for gas engine and belt-driven spray rigs. The Comet MC25 is one of the most popular pumps we install on our own power sprayers. It's compact, reliable and a great match for pest control and lawn care rigs.
Comet Pump Parts and Repair Kits
A worn diaphragm or valve doesn't mean you need a new pump. Our Comet diaphragm pump parts include diaphragm kits, valve kits, seals and other wear parts, so you can rebuild your pump and get back to work. Change diaphragms and check the oil regularly, and replace the oil immediately if it looks milky. That's a sign a diaphragm has failed and chemical is getting into the crankcase.
