ISPL 2415 Welded Metal Bellows Seal
ISPL 2415 uses welded metal bellows in place of springs and O-rings, so nothing grooves or frets the shaft. It is inherently pressure-balanced and most often used on thermic fluid.

FAQ
Questions buyers ask
Why metal bellows instead of springs?
They load the faces evenly, clean themselves, and remove the O-rings and wedges that groove a shaft.
What do you need from me to quote?
Shaft size, speed, temperature, pressure and the fluid. A photo of the old seal or its nameplate helps.
How long does delivery take?
After order confirmation: 2 days from stock, 2 weeks for a new seal.
