Slurry Pump Wear Parts: Have You Tested Yours?

GIW proudly announces new materials and ongoing laboratory testing that will dramatically improve pump wear life and reduce pump costs — both now and into the future.

In the harsh environment of the oil sands mining operations in Canada, slurry pumps are subjected to extreme abrasion and wear. Oil sands customers need their pumps to run as long as possible without maintenance downtime.

To respond to this need and the needs of all our customers, GIW has developed two new materials that dramatically improve pump wear life — and keep pumps working longer.

New GIW Pump Materials
GIW researchers have developed two new materials that extend the life of pump wear parts in extreme applications. These materials are being used and tested in the oil sands and will soon be available for other markets.

Endurasite™

Endruraclad™

  • lab tested and field approved
  • excellent results on impellers in tailings
  • up to double the wear life for these parts
  • less maintenance, longer wear life translates into more production
  • material applied and bonded to white iron surface
  • wear life can increase to over three times

Proven longer pump life
All GIW pump wear parts are built to last. But GIW enhanced those parts even further by developing a new white-iron alloy. The result is Endurasite™, a new material that has been proven in the field to increase wear life up to double the life of wear parts.

GIW is able to make all our pumps’ essential wear-related components — shells, impellers and liners — from this new material.

Endurasite differs from GIW’s Gasite® material, which has until now been the gold standard for pump materials. A new mix of materials is processed through more complex steps to achieve the unique properties that set it apart from standard white irons.

Because of the additional manufacturing steps involved, production of Endurasite is more costly than Gasite. But customers who require extended wear life will immediately see significant value in the reduced downtime they experience.

Tested in the field since 2009, Endurasite is currently available to oil sands customers and will soon be available to other markets as well.

A smarter surface for suction liners
GIW has added another wear-resistant feature with its new Enduraclad™ material.

For this new technology, GIW starts with a wear part made from Gasite or Endurasite. Then, Enduraclad material is applied to the white-iron surface — an extremely difficult and technical process developed by GIW’s metallurgical scientist. The Enduraclad actually bonds to the surface of the wear part, creating an extraordinarily hard and wear-resistant surface that delivers a wear life up to three times longer than normal materials.

Enduraclad use has been expanded and is now available on other essential wear parts.

These new materials were developed in-house by GIW engineers — not by an outside firm. As such, they are tested and approved in GIW’s labs under our real-world testing conditions.

This in-house materials development process is unique to GIW. Scientists and engineers at our Hydraulic Test Lab work continuously to improve existing materials and create new and improved materials for every real-world application our customers encounter.

An example is our Large Rock test, which concluded in August. Many labs do scale model testing, or they test materials with fine rocks and sand to determine wear. But our customers tell us that fine rocks and sand aren’t the problem in their applications. They are seeing large rocks — and those large rocks do significant damage to their pump parts.

To help our customers meet the demands they face in the field, we set up a full-scale large rock test. We constructed a pipeline and inset bars of each of our new materials inside the pipeline. Then, we pumped rocks six to eight inches in diameter through the pipeline to see how our materials stand up to the beating.

During testing, the metal bars were removed at intervals to measure wear. In addition, as the large rocks broke down into smaller pieces, more large rocks were added to accurately simulate actual mining conditions.

From this test, we have collected significant amounts of data that we can use to further improve our materials and parts designs.

The GIW Hydraulic Lab is one of the largest labs of its kind in the world, and only in such a setting is it possible to construct these types of full-scale, real-world tests.
