  DGC pump is a magnetic driven multi-stage centrifugal pump with double-layer volute. This product is designed to convey fluid at low flow with high head. This product features advanced and novel structure design, hydraulic design and magnetic path design, with technology at the leading level in China. Highlａnd is the first to successfully apply the magnetic driving technology in multi-stage centrifugal pumps, solving the question of high power and large gap magnetic path design, at the leading level in China. It also solved issues of axial force balance of multi-stage pumps at high working pressure and static sealing, and the matching of magnetic driving coupling and bearing failure monitoring device, further ensuring the long-term safe and reliable operation of pumps.
This product is suitable for conveying inflammable and explosive, toxic, harmful media containing no solid particles and other media requiring no leakage, and allowing no contamination by sealing isolating liquid. It is extensively used as liquid hydrocarbon pump in oil refineries, methanol, ethyl glycol and ethanol amine pump in chemical sector, amine circulating pump in natural gas sector, drain pump in power plants and boosting water injection pump in oil fields.
