GDF Teflon lined vertical pipeline pump

CDF series over-current parts are manufactured by high temperature annealing process, a new type of pipeline centrifugal pump with strong corrosion resistance. The pump impeller is directly connected to the motor through the support, the structure is compact, the selection of WB2 bellows external mechanical seal, shaft seal stable and reliable, equipped with external bellows mechanical seal, grinding material: alumina vs tetrafluorine, silicon carbide vs tetrafluorine, cemented carbide VS cemented carbide, vertical design occupies a small area, import and export are on a horizontal line, no need to change diameter, can be multiple in series, can be pressurized with limited space or linear pipeline. Widely used in alkali, chemical foil, pickling, medicine, iron and steel and other industries.

Advantages: the over-current parts adopt high-temperature return process, which can fully release the internal stress of the lining plastic and avoid cracking. At the same time, the plastic lining fits more closely with the metal surface, and the plastic layer of the working lining is still firm and stable even in the high temperature environment.

Where you need to use a vertical pump:
1. Pumping deeper groundwater. Liquids such as oil or brine need to use vertical deep well pumps. Another reason why the large single suction pump is vertical is that the water lubricated bearing with simple structure can be used. The load of the small lubricated bearing is small, and the wear please increase the life of the bearing.
2. Some high-pressure and small-flow pumps are prone to unstable operation because of the large number of stages and slender pump shaft. one of the measures to change this situation is to use vertical pumps and bear certain pulling force.
3. In the place where the water level changes greatly, the pump should be installed according to the low water level. If the vertical one is adopted, the area of the station can be reduced and the earthwork can be reduced. Reduce investment in infrastructure. Large single suction centrifugal pumps and axial flow pumps are mostly vertical.
