From the market of the pump we know that each type of pump has sealing performance, so what kind of pump seal is the best? The advantages of three kinds of common pumps: magnetic pump, shielding pump and mechanical seal pump are compared.
One, mechanical seal pump
1. Leakage
2. Complex mechanical seals and their piping
3. High rate of sealing and bearing maintenance
Two, shielded pump
1. No leakage
2. No mechanical seal is needed
3, return to the manufacturing plant maintenance - high cost, long period
4, graphite axis - easy to wear
5, small internal space - impatience of particles
Three. Magnetic pump
1. No leakage
2. No mechanical seal is needed
3. The site maintenance is simple
4, silicon carbide bearing -- long life
5. The internal gap is large -- the resistance to particles
By comparing the above advantages, it is not difficult to find that the sealing effect of the magnetic pump is the best.
