YTL series desulfurization submersible pump

1FYXCharacteristics of nitric acid submersible pump

FYXThe series vertical nitric acid submersible pump is a single-stage single suction long axis submersible centrifugal pump. The pump does not have a sealing structure, which solves the maintenance problem caused by seal wear and is suitable for conveying temperatures of0～105℃, medium without solid particles or abrasives, high pump efficiency and no leakage.

Performance range of pump: flow rate of1.6～400m3/hThe lift is5～80m.

2、 Selection of Material for Nitric Acid Submerged Pump

1.high-purity aluminum

High purity aluminum has excellent resistance to concentrated nitric acid corrosion at room temperature, but the disadvantage is that the concentrated nitric acid temperature exceeds60℃, high-purity aluminum is corroded more severely, so the high-purity aluminum material submersible pump can only deliver working temperatures within60Nitric acid below a certain degree.

2.High silicon iron

High silicon iron has good resistance to concentrated nitric acid corrosion in various temperature environments, but its fragile nature and poor mechanical properties limit its use in concentrated nitric acid transportation.

3.tetrafluoro

Tetrafluoride is below120It is also resistant to nitric acid corrosion in temperature environments, and due to its own characteristics such as relatively soft mechanical properties and easy aging. These also limit the use of PTFE pumps in nitric acid equipment. At present, it is mainly used for mechanical seals and gaskets. Use other materials to make the pump.

4.304L

In nitric acid,304LCorrosion resistance ratio316LHigh, because the presence of molybdenum will reduce the corrosion resistance of stainless steel in nitric acid. In boiling65%In nitric acid,304LThe corrosion rate is0.15mm/In the year,316LTo exceed0.3mm/In the year,

304LApplicable to concentration68%Below, the temperature ranges from room temperature to boiling point.
