Can a gear pump be used in this situation?
Thread Content
The material contains glycerin, 30% acid salts, sodium chloride, and the temperature is 120°C. Can a gear pump be used in this situation?
To determine it, viscosity analysis is required
I think we should still consider the issue of corrosion – can gear pumps withstand salt and acid corrosion?
Corrosion resistance is related to the material; in acidic conditions, Hashi alloy or Mengnaier material should be chosen. I’ve forgotten what the characters are; I’m sorry I had to use pinyin.
Gear pumps cannot be used; since the viscosity of your fluid is not high, opt for a centrifugal pump. Also, pay attention to the details – the flushing scheme for the mechanical seal needs to be chosen appropriately. The material of the centrifugal pump is also very important!
The viscosity is not high, but the salt particles formed by the precipitation of sodium chloride will wear out the mechanical seal surface, causing the mechanical seal to become damaged after a short time.
Dear, use your brain – for a mechanical seal, using cemented carbide for the double-face sealing of cemented carbide is a good option! Add a scientific rinsing protocol, and it’s perfec~t!
