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 71 frame B3/B14 electric motor. This makes it an ideal component for building a custom, electrically-powered sprayer rig, perfect for use in greenhouses, workshops, or any location where a petrol engine is not suitable. 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.

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 suitable electric motor. 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 system.
