High-temperature, Stationary Edge-welded Metal Bellows Seal Type is604

The Type is604 is a high-temperature, general-purpose, stationary edge-welded metal bellows assembly for applications to 425C/800F. Available in either AM350 or Alloy 718, its high-strength design provides maximum reliability. The stationary bellows design accommodates high shaft-to-seal-chamber misalignment. Unlike rotating seals that must flex on every revolution to accommodate shaft-to-seal-chamber misalignment, the stationary Type is604 adapts to this condition by flexing only once during installation. This reduces seal movement, resulting in increased seal life. Typical applications include hot hydrocarbons, aqueous solutions, aromatic fractionation products, crude oil fractionation products and heat transfer fluids.

Technical Description

Product Description Type is604

Type is604 – High-temperature general-purpose stationary bellows assembly capable of handling high shaft speed applications and high shaft-to-seal chamber misalignment.
Type is606 – High-temperature rotary bellows assembly with drive lugs under the bellows for additional rotational drive in viscous or thermosetting applications.
Type is609 – High-temperature rotary bellows assembly with narrow cross-section design for easy fit.
