Comet MC18 2 Diaphragm Pump - Acid & Chemical Resistant

The Comet MC18 2 Diaphragm Pump is a specialised solution for applications that require resistance to corrosive and aggressive chemicals. Specifically developed for the distribution of water-soluble detergents and paints, this pump is an essential component for SoftWash systems, pest control, and other tasks involving chemicals that would damage a standard pump. Built with high-quality Viton diaphragms and a robust polypropylene (PP) body, the MC18 is engineered for longevity and reliable performance when handling harsh substances.

Designed for seamless integration, this pump is suitable for direct mounting onto a 3/4" shaft 4-stroke engine, making it an ideal choice for the DIY power user or professional looking to build a custom, chemical-resistant rig. It operates at 1450 RPM and delivers a maximum pressure of 15 bar (217 PSI) with a flow rate of up to 11.9 litres per minute, providing a controlled and consistent output. The pump comes equipped with an integrated pressure regulator for precise control, and its compact size and straightforward connections—a 16mm hose barb inlet, 10mm outlet, and 12mm bypass—ensure a simple and efficient setup.
