ECCENTRICALLY SUPPORTED ROTOR FOR FAST VIBRATIONS AND PULSATING JETS TO DISINTEGRATE DEPOSITS OF UP TO 10CMS THICK. The Rotopuls nozzles were conceived to remove medium to hard deposits in pipes of plastic, steel or concrete. Important: Rotopuls nozzles develop strong hydraulic impacts and vibrations. This can possibly cause damage in some types of pipe (e.g. earthenware pipes, thin-walled plastic pipes or badly - bedded PVC pipes) If out of stock, we can order in.  Please allow 3-4 weeks from date of order.
