Wärtsilä Pumpsafe Water WCS Bearing

The Wärtsilä Pumpsafe WCS bearing series is the latest generation of water lubricated composite bearings developed by Wärtsilä, offering an environmentally friendly, low wear – long life cycle solution for pumps and other industrial applications.  Originally developed for the demanding marine market, they are widely used in hydropower and industrial power generation plants where there is rotating equipment.  A unique Wärtsilä feature is that these bearings can be provided as a hybrid [combined] or packaged shaft system incorporating the appropriate Wärtsilä water lubricated seal.

Wärtsilä Pumpsafe WCS bearings are available as bushes, shells or segments and can be supplied as part of a package, retained in a housing and tailored for easy installation.  The housing can be made from Wärtsilä’s standard spun cast aluminium bronze or Wärtsilä’s new light weight and strong structural composites which can reduce the weight of the housing by up to 75%, without detriment to its strength, support or operation.  Both housings and bearings can be fully split for easy assembly with the shaft left in-situ. 

A unique Wärtsilä feature of the bearing is that it can be provided as a hybrid [combined] or packaged shaft system incorporating the industry/application appropriate water lubricated seal.  

Due to the superior material quality developed by Wärtsilä, it can also vastly improve both the safety and operational elements of installation, commissioning and maintenance.  Wärtsilä Pumpsafe water lubricated bearings are also cost effective as they have less material content, less complexity and the lubricant is freely available.  They are also environmentally compliant, avoiding unplanned costs and minimising risks associated with current, and future, regulations and restrictions.

Wärtsilä’s in-house material science development strategy combined with product manufacturing and quality control standards, ensure that lead-times are controlled and the product is highly customisable.

Applications/Options:
Industrial applications including process industries, power generation, mining etc.
Hydropower & tidal power turbine guide bearings, guide vane and linkage bushes and pumps
Can also be supplied with sensors to track performance [like wear and temperature] and inputs into plant level planned maintenance systems.
