Click on the Surgeguard to find out which sizes are available.
| The Surgeguard consists of a liquid-filled bladder in a container. The process liquid only comes into contact with the bladder and the connection plate, so compatilibity is only an issue with those parts. This means that even when the process liquid is corrosive, the bulk of the unit can be made from conventional materials, and more expensive resistant materials only need to be used for the bladder and connection plate. In addition, the bladder is a one-piece moulding, unlike many other bladders which are made in pieces then glued together, so compatibility issues between the process liquid and the glue are also avoided. |
