Abstract: A powerful, high speed and self-lubricated pump (ZS350×480 pipeline pump) is developed to increase output and realize tight-line transportation in Qinjing Oil Pipeline. Compared with DKS450/550 oil transfer pump, the former is characterized by high efficiency, low energy consumption and easy maintenance. Introduces in detail the processes of developing and transforming of ZS350 × 480 pipeline pump and 1 250kW motor. Through trial operation in Qinjing Oil Pipeline over two years, the pump maintains good technical condition and all parameters get to design requirement, thus brings considerable economic and social benefits.
