ZYB diesel pump adopts self-sealing lubrication and automatic clearance adjustment structure, and its main parts are made of high wear-resistant materials. ZYB diesel pump has the characteristics of compact structure, good self-priming, high efficiency and strong adaptability. When the conveying liquid contains impurities, the working life of ZYB slag pump is more than 10 times longer than that of general gear pump. The design of ZYB slag oil pump fully considers the interchangeability with KCB series ordinary gear pumps, and its shape, installation size and technical parameters are exactly the same as those of KCB series gear pumps. Therefore, this type of pump is also called KCB series "strong type". ZYB slag oil pump shows the important characteristics of long pump life and stable pressure when conveying lubricating and impurity-free media. This ZYB slag oil pump is suitable for conveying heavy oil, diesel oil and coal tar containing nonmetallic impurities, as well as various impurity-containing and less-lubricated media with temperature not higher than 200℃ and viscosity not higher than 150mm2/s in grain and oil, chemical industry, building materials, daily chemical industry and other industries. ZYB diesel oil pump is especially suitable for occasions requiring stable working pressure and long-term continuous operation. For example, ZYB slag oil pump is not suitable for conveying corrosive, metallic impurities, sand and gravel impurities with a particle size greater than 3mm, high volatility and low flash point media. Such as gasoline, benzene, etc.
