DF series multistage centrifugal pump is a kind of single suction multistage corrosion resistant chemical centrifugal pump, which is specially designed for conveying corrosion resistant liquids without solid particles in the industries of chemical industry, petroleum, metallurgy, mining and paper making, etc. The temperature range of conveying medium is -20℃~105℃, the allowable inlet pressure is 0.6MPa. It has the features of strong corrosion resistance, reasonable structural design, reliable sealing, smooth operation, low noise, and long service life.
Product Details:
DF series centrifugal pumps are consisted of stator, rotor, bearing, seal and other parts. The stator part can be fixed by screws through the tie rods, so as to form a sealed working chamber. The rotor part is made up of shaft, impeller, shaft sleeve and balancing disk device, which can be driven by the transmission of the shaft, driving the impeller to rotate and generate centrifugal force, thus driving the medium flow. Its sealing part here can choose packing seal and mechanical seal, packing seal is mainly used for the leakage requirements are not strict or the medium contains solid particles of the occasion, while the mechanical seal is suitable for high temperature, high pressure, corrosive, the leakage requirements of strict working conditions.

Application:
It is widely adopted in mining, chemical industry, petroleum, metallurgy and papermaking, etc. It is appliable for delivering liquids without solid particles, corrosive, and with temperature not exceeding 80℃, and it can also be used for conveying hot water, oils, corrosive or abrasive-containing mediums, etc. by changing the material of the pumps, the sealing form and increasing the cooling system.
Advantage:
1. Its overflow parts can be made of 1Cr18Ni9, 1Cr18Ni12Mo2Ti, 1Cr18Ni9Ti, etc. according to different conveying media, or other corrosion-resistant materials according to the requirements of the users, which is suitable for conveying corrosive liquids not containing solid particles.
2. Adopt energy-saving and efficient hydraulic model, high efficiency, wide range of performance, safe and smooth operation, low noise, long life, easy installation and maintenance.
3. The inhalation port is horizontal side inlet, the spit outlet is vertical outlet, the whole rotor is supported by the rolling bearings at both ends.
4. The shaft seal adopts soft packing seal or mechanical seal, which is safe and reliable, simple in structure and convenient in maintenance.
