Second generation pump tailored specifically for sand applications

Weir Minerals has announced the global launch of the second generation Warman WGR pump for the sand and aggregate market.

The replaceable impeller and liners are manufactured with Linatex premium rubber, which is renowned for a strong wear performance and lengthening maintenance intervals for wet sand applications.

Furthermore, the streamlined slurry flow path reduces recirculation and energy consumption, making it suitable for sand and aggregate sites.

“Sand can be extremely abrasive and often rapidly wears down a slurry pump, which is why we have lined the WGR pump with Linatex rubber,” said Mark Doyle, Weir’s global product manager for Linatex rubber.

“The properties in our Linatex rubber protect the WGR pump from abrasive materials and extend its wear life. Linatex rubber is a proven performer in sand and aggregate applications around the world.”

Linatex is made in a unique liquid phase manufacturing method, providing exceptional wear properties that allow it to last longer in service, lower operators’ total ownership costs and simplify change-outs.

The Linatex wet-end components are precision-moulded and designed specifically for the Warman WGR pump.

Weir Minerals has made significant enhancements to the original WGR pump and specifically designed and engineered it for sand and aggregate applications. The second generation pump features several innovations, including improved hydraulic design, enhanced gland options, simplified wet-end and added features for improved safety and reduced maintenance.

“We’ve listened to what our customers need and innovated our WGR pump to work harder,” said Marcus Lane, Weir’s global product manager for centrifugal pumps.

“We have improved the hydraulic performance by streamlining the slurry flow path, which reduces recirculation and energy consumption.

“We have also simplified the wet-end, added a drainage plug for ease of maintenance and can now offer gland seal options for customers.”

The large diameter expeller seal design prevents slurry leakage and protects against high inlet pressures, reducing maintenance and adjustment frequency. Additional gland seal options are also available, including a remote adjusting patented D-Gland seal, which provides parallel adjustment of the sealing faces.

“Gland seal water is typically unavailable to operators in sand and aggregate applications, which is why we built the dry gland seal arrangement into the pump,” Lane said.

“We have engineered it with our customers in mind, ensuring they can successfully pump their slurry without additional gland sealing water and without risk of leakage.”

The second generation Warman WGR pump, combined with Linatex premium rubber, is backed by Weir Minerals’ commitment to deliver outstanding performance and results.

Weir Minerals specialises in providing high quality solutions to the sand and aggregate markets, to help customers run their sites to maximum capacity.

In 2018 the Warman pump celebrated 80 years in the extractive industry. Charles Warman invented the Warman slurry pump in Kalgoorlie in 1938. It was a hard-wearing slurry pump that used replaceable liners and a replaceable impeller.

The Weir Group acquired the Warman pump in 1999 and has continued to perfect Charles Warman’s original design.
