Comet MC18 2 Diaphragm Pump - General Use

The Comet MC18 2 Diaphragm Pump is a compact and reliable spraying solution designed for direct mounting onto a 5/8" shaft 4-stroke engine. This makes it an ideal component for the DIY power user or small-scale farmer looking to build a custom, portable sprayer rig. It delivers a consistent maximum pressure of 15 bar (217 PSI) and a flow rate of up to 11.9 litres per minute, providing ample power for a range of tasks, from targeted weed and pest control to applying fertilisers on a small scale.

Built with a durable Nylon body and hard-wearing NBR diaphragms, this pump is designed for a long service life with common agricultural chemicals. It operates at 1450 RPM, which is perfectly matched for direct coupling to a petrol engine. A key feature is the integrated pressure regulator, which allows you to easily adjust the output pressure to suit the specific task, ensuring professional and precise results. The pump's straightforward connection options—a 16mm hose barb inlet, a 10mm hose barb outlet, and a 12mm hose barb bypass—make it easy to integrate into your existing system.
