Why do some water pumps require seal water while others don’t?
Thread Content
The mechanical sealing method of the water pump determines whether seal water is needed, but from a process perspective, it would be better not to require seal water – this eliminates the hassle of installing piping and also the need to drain the seal water on-site.

It is recommended to take a look at the flushing solutions for API682 machine seals before asking this question; different media and operating conditions require individual consideration, as there is no one-size-fits-all solution. Self-flushing, external flushing water, isolation fluid, compressed air, and nitrogen sealing – all of these have their reasons behind them, based on technical considerations. It’s not done carelessly. Why is there an unknown advertisement appearing below my messages? What’s going on?
While ensuring good performance and durability, the sealing and flushing solution should be selected appropriately; there is no one-size-fits-all approach.
Mechanical seals all require flushing and lubricating water. However, whether external flushing water is needed is determined by the conditions of the medium being transported, the structure of the water pump, and the structure of the mechanical seal (cavity)
Drain it? Are you referring to the rinse water, or the cooling water on the gland?
Based on the medium pumped by the pump, temperature, etc
This is determined by the medium. There is also a sealed flushing option. It can’t be changed casually
It’s better for people not to eat; there’s no need to buy ingredients or spend money on cooking, but one will still feel hungry. Take a look at the sealing solutions – getting rid of waste on the spot is perhaps one of the options available, but it can’t be generalized. Additionally, it is necessary to identify the main contradictions: what needs to be solved and what new problems have arisen.
Everything is determined by the medium conditions, including the pump type and sealing method
