What is the most reliable structure for a condensate pump?
Thread Content
Our factory’s original condensate pump used a packing seal, which would always leak a little; this pump operates with a clearance design. I would like to change it to a mechanical seal, as cooling water can be provided on-site. I would like to ask what the flushing scheme for the mechanical seal is? Which material for the O-ring inside is more reliable? Examples of pumps that have been operated in practice would be ideal.
It is normal for a stuffing pump to drip, as long as the number of drops per minute remains within the acceptable range; otherwise, the stuffing will burn out. If a seal-type pump is used, ordinary cooling water is sufficient.
What was said upstairs is correct – a packing seal will definitely cause dripping, but only at speeds within the specified range.
It is normal for a filling pump to have some leakage; replacing it with a mechanical seal comes at a high cost.
What’s the temperature? The mechanical seal flushing scheme can only be determined based on the existing cavity and installation dimensions
For packing seals, no more than 10 drops per minute is acceptable; replacing them would result in high operating and maintenance costs
Use fillers whenever possible; they are easy to replace and result in lower maintenance costs
The type you mentioned can also be replaced with a mechanical one; it’s more effective. As long as the water pump doesn’t stop operating for long periods of time, mechanical seals generally don’t cause any problems. They are better than packing seals, but each has its own advantages. Packing seals are easier to maintain and have lower maintenance costs, while mechanical seals require more effort for maintenance and have higher costs. There is no loss of liquid with mechanical seals, so they usually don’t present many problems. With proper use, a set of mechanical seals should work fine for about 2 years. With packing seals, it’s likely that inspections will be needed every few days. Well, it depends on your choice, :)
Hello, I want something that requires less maintenance. Do you have any information on pumps that have been successfully used in practice? Or a rinsing regimen? What is the material of the O-ring in a mechanical seal? I can buy it to test its effectiveness, thank you
Condensate pumps are quite special; they are very prone to cavitation, and cavitation is what most easily damages mechanical seals. If the packing seal leakage is within the acceptable range, use a packing
What size pumps did your company use before? What does an O-ring mean? There’s no O-ring inside, right? And what’s the temperature of the condensate water, roughly?
