Flood control and drainage pumps Diesel - Diesel flow pump - Rural water pump: 1 Features: simple structure, reliable, easy fitting, and high efficiency, small body, light weight. 2 Transmission: direct drive and variable speed drives. Common power machine is the motor and the diesel engine. Order should be clear power machine model (power, rpm) in order to determine the coupling or pulley specifications. 3 pump direction: to the pump inlet to see, the impeller is generally counter-clockwise, (650KDW-5, -7, -10 pump clockwise).


Flood control and drainage professional diesel pumps - diesel mixed flow pumps - pumps in rural areas :
        The combined effects of centrifugal force and the thrust generated by the work of the use of the impeller rotation , oblique outflow , also known as mixed flow pumps , there are two worm -type ( horizontal ) and the guide vane ( vertical ) . It combines the advantages of centrifugal and axial flow , simple structure, efficient wide area , easy to use , suitable for plain polder farmland irrigation and drainage pumping station. China developed the mixed-flow pump , the volute of the head 5 ~ 12m, flow 900 ~ 4000m3 / h; guide vane -type head 3 ~ 25.7m, flow 45 ~ 20160m3 / h. Two guide vane pump soap River County, Jiangsu Province, Suqian pump station installation. Impeller diameter 5.7m, flow 80 ~ 100m3 / s, lift 6 ~ 12m, speed 75r/min, maximum efficiency of 92.1% , matching power 7000kW, is one of the world's major operational flow pump . Mixed-flow pump is one of the technology development focus of international pump industry. It will replace the centrifugal and axial part of the work . In Japan , the Soviet Union , Australia and other countries , mixed-flow pump for maximum efficiency are reached or exceeded 90%.
