RCB series of high viscosity pump for transporting asphalt incubated at room temperature thickening, solidification or the crystallization temperature and easy to maintain a certain flow of a medium designed, such as asphalt, wax, rosin and similar nature liquid temperature no higher than 200 ℃. RCB series of high viscosity asphalt and steel heat pump is divided into two kinds of ordinary materials, all with insulation jacket. RCB series of high viscosity asphalt insulation pump for conveying non-corrosive, non-solid particles, at room temperature, there is coagulation of the media, especially suitable for outdoor installation and cold areas in the process where the media need insulation, medium temperature up to 250 ℃, the viscosity of 5-1500cst. RCB series of high viscosity pump pumps asphalt insulation has a hollow mezzanine, and has import and export flange can be used for thermal oil, steam, hot water and other media to be pumped liquid and heat insulation and cooling. Botou day extension Pump Co., mainly produces gear pumps, rotor pump, stainless steel pumps, high viscosity pump, screw pump, heat pumps, marine pumps and other 15 series over 300 kinds of product specifications, complete specifications, wide application .
