The Rho-Flush 1000 from Rhomar features ultra-high fluid flow to accelerate the cleaning process of hydronic systems clogged with corrosion. The 39 gpm flow rate provided by the IP55-rated pump motor enables cleaning fluids such as Hydro-Solv and Skale-X to quickly dislodge debris from walls of pipes and heat exchanger surfaces. The acid-resistant tank has a 15-gallon capacity. It can withstand 167 degrees F and has a maximum head of 78 feet. It is equipped with an instantaneous flow reverser, 110-volt electrical connections and comes with hoses and fittings. The pump can be connected in series with the Rho-Mag, which helps remove magnetic materials recirculation. It can also be used to fill/purge hydronic systems. 800/543-5975; www.rhomarwater.com.
