ZYB series of residue gear pump self-styled lubrication, automatic adjustment of the gap structure, to parts are high wear-resistant materials. Has the advantages of compact structure, good self-absorption, high efficiency, strong adaptability and other characteristics. When transporting liquid with impurities, the working life of pump is 3-5 times longer than that of general gear pump. The design of this pump fully consider the interchangeability with KCB series ordinary gear pump, shape and installation dimensions and technical parameters and KCB series gear pump exactly the same. Therefore, this type of pump, also known as KCB series "strong type", in the transport of lubricating medium without impurities even more shows the pump's long life, the pressure stability of the important features. This pump is suitable for conveying heavy oil, diesel oil, coal tar, grain and oil, chemical industry, building materials, daily chemicals and other industries containing impurities with non-metallic impurities at a temperature not higher than 200 ° C and a viscosity of not more than 150mm2 / S. Of various media. This type of pump is more suitable for demanding work pressure stability, long-term continuous work of the occasion. For example: strong lubrication system, fuel combustion system, fuel delivery and injection. ZYB residue gear pump purposes: for glass, foam, building materials, chemicals, construction, petroleum, grain and oil industries. ZYB residue pump structural features: This series of pump body, pump cover, gear, shaft seal, gland, the pump pressure, the delivery of residual oil and waste oil performance is good, tooth surface after special treatment, anti-torque force advantages .
