The company traces its establishment to 2004. Its profile describes computational fluid-flow and three-dimensional structural design, computer-aided mould production and silica-sol casting. Selection consultation, installation guidance, maintenance and spare parts are included in its published service scope.
The QJ submersible family illustrates Runjin’s water-engineering offering. The catalog covers a broad range of hydraulic and electrical configurations and specifies water-quality conditions. These limits are useful for screening an application, but an individual well or intake still requires a matched pump curve, motor, cooling arrangement and installation drawing.
The reviewed range now distinguishes QJ water service, QH seawater service and WQ sewage handling. Salinity and immersion govern the seawater material selection, while solids, wet-well levels and retrieval arrangements govern sewage-pump selection. These families should be compared by the intended liquid and installation before comparing motor sizes.
