TLB heavy oil pump belongs to the cam-type positive displacement pump. Is based on the TLB heavy oil pump to improve the product. The pump is made of special wear-resistant material, excellent wear resistance, service life is 3-5 times that of ordinary asphalt pump. Reducer for transmission efficiency and efficiency of NGW planetary gear reducer, the pump to adapt to a wide range of viscosity, from 0.02Pa.S to 100Pa.S medium can be transported. And has low speed, high efficiency, smooth operation, self-priming capability, easy operation, the pump can be preheated and so on. Is the petrochemical, oil, asphalt, food, light industry, the ideal transportation equipment.
