A roots blower pump is a positive displacement rotary lobe pump that operates by pumping a fluid with a pair of meshing lobes .By forcing the medium from atmospheric conditions into a system with a given resistance (e.g. a water column, distribution network), the relevant pressure increase is achieved. The roots blower will operate at a controlled output level to overcome this resistance.
Design, production and installation of proper equipment for harsh environments and toughest applications requires a great deal of know-how and long years of experience. Rongheng manufactures roots type positive displacement blower packages for extensive range of industrial applications. Simple installation, low maintenance need, long years of problem free service, endurance for harsh environments are key features of Rongheng blowers. Wide range of roots blower models and accessories are available depending on process parameters and site conditions.
