PNSL vertical sand suction pump with features of high efficiency, energy saving, simple matching, easy to use ,etc. Not only can be a single pump work, but also can be more pump parallel to suck sediment to the collection pipe, And PN-type sand pump used in series to achieve Long-distance transport of sediment and sand.Water dredging, excavation, blown the unit for water mechanization construction, is to simulate the principle of natural water erosion, by the role of water to carry out dredging, digging work, water pressure generated by high pressure pump, through the nozzle of water gun, High-speed water column, the impact of sand column sand, so that to wet the soil sand, disintegration, mixing mortar and mud mixture, and then by the vertical sand pump to enhance the transport through the sediment pipe to the battlefield.
Widely used in more sand and less water environment: beach, lake river suction of mud, dredging, embankment, coastal beach breeding plant excavation; fish pond dredging; low-lying land transformation; tailings extraction, sand ship unloading sand,etc.
1、Pump structure：Mainly by the motor bracket, the middle, pump cover, pump seat, impeller, shaft, guard, pump and other components.Pump seal：Skeleton oil seal with butter lubrication.Rotation direction of pump：From the direction of the power machine as a clockwise rotation.
2、Overflow parts using wear-resistant alloy material, hardness, high strength, long life than ordinary material 2-3 times.
3、Adjust the nut to adjust the impeller clearance, reduce leakage, improve efficiency, and make the impeller easy to disassemble.
4、The packing chamber seal is separated from the lower bearing seal, and both ends of the bearing are sealed with a frame seal to prevent the sediment from entering the bearing and extend the bearing life.
5、Impeller back to use vice leaves，So that the back pressure is reduced,reduce the axial force and prevent some of the debris into the sealed chamber,protect the seal to be less wear.
6、The pump structure is simple, easy dis-assembly and maintenance, supporting the installation easy to use.
7、The pump seal structure changes, to avoid the direct damage to bearing after the skeleton after the skeleton oil seal is damaged, bearing life has greatly improved.
