Zero emission seal family expanded

John Crane has added two new members to its Type 2800 family of gas lubricated, non-contacting, zero emission seals, bringing the total number of versions to six.

The Type 2800EX is fitted with an excluder – a device that reduces solids within the seal chamber. It is capable of handling up to 28% solids. The Type 2800MB incorporates a Sealol welded metal bellows and eliminates the need for dynamic O-rings.
