Pump industry suppliers to tell you: the material of sealing material commonly used chemical pump

chemical pump choice:

1, make the selected corrosion resistant chemical pump type and performance in accordance with unit capacity and head, pressure, temperature, NPSH, the requirement of the process parameters such as suction.

2, must meet the requirements of the dielectric properties of conveying of inflammable, explosive or toxic or precious medium pump, require no leakage of water pump shaft sealing is reliable or adopted, such as magnetic drive pump, to pump forhandling corrosive mediums, convection components with corrosion resistance materials, such as fluorine plastic chemical pump pump for conveying medium containing solid particles, convection parts adopt wear-resisting material requirements, use clean liquid wash shaft seal when necessary. Correct calculation of chemical pump procurement cost.

3, mechanical aspects of requirements of high reliability, low noise, small vibration.

chemical pump seal materials commonly used material:

1, ptfe asbestos packing the use of SMF temperature: - 100 ~ + 250 ℃, the suitable medium: weak acid, alkali and other corrosive medium.

2, oil-immersed asbestos pan-gen YS250, YS350: oil-immersed asbestos packing can be packing contains large amount of lubricating oil, small friction coefficient, compression. Applicable medium: steam, air, industrial water, heavy oil products.

3, carbon fiber woven packing is a kind of high strength, high modulus, new materials, it has high strength, elastic modulus, high temperature resistance, good resistance to chemical corrosion, thermal performance, and low thermal expansion coefficient, and have self lubrication. At the beginning of the run time should be tight packing gland, allowing medium has a small leak, run after a period of time, then gradually pressure, make the stuffing into the relatively stable stage, such as leak detection in operation, can tighten the packing gland for many times.

4, ptfe fiber braided packing, the product is divided into six grades. In use process, began allowing filler has a small leak, to be used for a period of time, after filling in a relatively stable state, then adjust gland. Must not too tightly on the start, in case burn out packing.
