Product Description

Metal Bellow Mechanical Seal For Water Pump

A welded metal bellows is a zero leakage dynamic seal capable of a great range of motion. The metal bellows is manufactured from sheet stock. The material of construction may be stainless steel, high nickel alloys, titanium or other alloys to suit the application requirements. The material thickness may range from 0.001" to 0.025" thick.
Stroke Comparison of Edge Welded Bellows:
Stroke of edge welded bellow Stroke of a typical formed bellow
* Stroke up to 90% in compression * Stroke limited to 10%
* Stroke up to 30% in extension
 

Flexibility characteristics of an Edge Welded Bellow:

Flexibility
* Edge welded bellows are capable of softer spring rate
* Axial, angular and radial

How Edge Welded Metal Bellows are manufactured:
Welded diaphragm metal bellows are composed of two contoured diaphragms - each constructed from thin stainless steel - are welded at the inside diameter to form a convolution. Capsules are formed when convolutions are stacked on a horizontal arbor and welded at the outside diameter.

Manufacture Specification

* Bellows should mostly work in compression, 20% extension max. For maximum life, always work in compression
* Nested height of bellows should have a minimum of .002" between max weld bead size for 3 ripple configuration
* Avoid imposing lateral offset while axial stroking. Severely degrades life
* Max pitch 1/3 of span
* Bellows free length will typically stabilize at 15 to 25% of as welded length
