Pump selection
Thread Content
Materials in the workshop tend to crystallize, and the pumps currently in use often suffer from seal leaks; I want to replace them but am not sure which type of pump would be suitable. Could anyone recommend some good options?
Single-face mechanical seal? A double-end face seal (with a flushing mechanism) can be considered:time:
What kind of material? What are the inlet and outlet pressures?
The description of this operating condition is too simple.
Consider using a packing seal to create a thermal insulation structure in which the pump is placed; this ensures that the temperature of the medium remains above the crystallization temperature when the pump is shut down. A seal with a flushing function can be used instead
Material crystallization usually occurs when the pump is stopped; if crystallization takes place during transportation, a slurry pump or a cam rotor pump should be used
It’s a heat-insulating magnetic pump, but I’m not sure whether it’s suitable for the medium used in your application.
If the material is free of impurities, a magnetic pump can be considered, along with heating and insulation.
What is the shape of the impeller, and the pump casing can be made insulated.
Bro, there’s not enough information. If the pump conditions permit, it is possible to switch to a double-seal design and implement a suitable flushing scheme. If that doesn’t work, use a magnetic pump; I’m not sure if the temperature conditions will be met or not.
