Comet MC8 2 Diaphragm Pump

The Comet MC8 2 Diaphragm Pump is a compact and reliable spraying solution designed for seamless integration with 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 7.8 litres per minute, providing the perfect balance of power and precision for small-scale applications like targeted weed and pest control or small-area fertilising.

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 simple to install and operate.
