Waterous' CMU fire pump is designed for industrial de-coking and de-scaling

Waterous introduces CMU fire pumps for industrial pigging, de-coking and de-scaling applications. Revamped for industrial cleaning of furnace tubing and coiling used in refineries around the world, the Waterous CMU pump outperforms other de-coking and de-scaling methods at a more efficient, cleaner and cost-effective rate.

With performance ratings up to 2250 gpm (8550 L/min), the CMU pump propels the oblong metallic cleaning device, or “pig,” with high-pressure waterpower through the coil furnace tubing at rates of 3,500-4,500 rpm. The process encompasses initial hard cleaning, secondary cleaning and final cleaning and polishing.

Unlike other methods used for industrial de-coking and de-scaling such as burning, which is often time consuming, or sandblasting, which can be harmful to the tubing, using the CMU pump to propel the pig cleans the furnace components quickly without damaging the coils or tubing. Driven by a direct application engine, the CMU pigging application is a completely self-contained unit, mounted on a semi-trailer. The unit also contains a hose and tank collection unit designed to house the contaminated water that accumulates during the cleaning process.
