COMPOSITES (PEEK)

Replacement of bearing bushes and wear rings in bronze, metal, PTFE or rubber for pumps.

Humitab can offer you the following wear-resistant composites composed of PEEK and carbon fibre:

• CF30 ( 70% PEEK + 30% carbon fibre ) - Tube - Radial bearing
• CW70 ( 30% PEEK + 70% carbon fibre ) - Tube - Radial bearing
• CP50 ( 50% PEEK + 50 % carbon fibre ) - Plate - Axial bearing
• Pure PEEK - Tube - Rod
• Graphite Filled PEEK - Tube - Rod

Advantages

Less electricity consumption

Less vibrations

Possibility to decrease the gap between impellar-pumphousing and bushing-sleeve

Less maintenance and downtime costs

CF30

CF30 is a temperature and pressure moulded composite consisting of 70% PEEK and 30% carbon fibre. It is the perfect bearing material for vertical pumps and for wear rings on impellers.

Advantages

High temperature reach : 150°C

Excellent chemical resistance

High sliding properties

Also suitable for use in abrasive environments

Nonsoaking - will not swell

CW70

CW70 is a wound tube material consisting of 30% PEEK and 70% carbon fibre. This combination results in an exceptionally strong material with superior qualities.

Advantages

Very high temperature reach : 270°C

Very broad chemical resistance

Excellent sliding properties

Nonsoaking - will not swell

Very low coefficient of thermal expansion

CP50

CP50 is a material with wound carbon fibres that are compressed together with PEEK into plates by means of an autoclave.

Advantages

Very high temperature reach : ca. 300°C

Very broad chemical resistance

Incredibly strong

Applied as axial bearing and segment bearing in vertical pumps
