Comet MC18 2 Diaphragm Pump - Acid & Chemical Resistant

The Comet MC18 2 Diaphragm Pump is a specialised, chemical-resistant solution for applications involving corrosive substances. Unlike pumps with standard components, this model is built with high-quality Viton diaphragms and a robust polypropylene (PP) body, making it an essential component for SoftWash systems, pest control, and distributing water-soluble detergents and paints. This construction ensures a significantly longer service life and reliable performance when handling harsh chemicals.

This pump is specifically designed for integration with a 71 frame B3/B14 electric motor, providing a powerful and efficient solution for stationary or mobile chemical spraying rigs. 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, offering a controlled and consistent output for precise application. The pump comes equipped with an integrated pressure regulator for easy pressure adjustments.Its straightforward connections—a 16mm hose barb inlet, 10mm hose barb outlet, and 12mm hose barb bypass—ensure a simple and efficient setup.
