The diesel engine water pump series draws on ordinary centrifugal pumps, multi-stage pumps, double suction pumps, self-priming pumps, mixed flow pumps, etc., and the above pump types are changed to diesel engine connection methods; Direct connection, clutch type, pulley type, transmission shaft type and other connection methods, different types of pumps are adopted according to the usage environment and conveying medium. There are three sealing forms for ordinary diesel engine water pumps: soft packing, mechanical seal, and skeleton oil seal. Changing the materials of the sealing ring, shaft sleeve, and impeller can transport turbid water containing sediment. The sealing form of special media is customized according to on-site customers. Most diesel engine water pumps are installed horizontally, while vertical installation structures require the installation of a right angle reducer. The rotation direction of the diesel engine water pump is generally clockwise when viewed from the diesel engine end. Suitable for emergency use in factories, mines, fire protection, power station water supply, farmland drainage and irrigation, and water conservancy projects.
