The Pipemaster high-pressure hose rotating system from Hammelmann Corp. is used to remove both soft and very hard deposits from the insides of pipes and pipelines, including those with bends and vertical sections. The slow rotation speed results in increased cleaning/removal rates. Powered deployment and retraction can remove pipe blockages. A high-pressure supply hose line is fixed between the pump and the rotary joint on the hose-rotating unit. A second hose is connected to the rotary joint and runs via the deployment unit into a protective hose to the positioning device at the work piece. The rotating unit is driven by compressed air at 60 psi and comprises a pneumatic motor with gearbox, a pneumatic maintenance unit, the high-pressure rotary joint and a pneumatic control system all mounted on a three-wheel trolley. 800/783-4935; www.hammelmann.com.
