Landia’s pumps and mixers rock!

Posted: Thursday 19th September 2013

Chopper pumps and mixers made by Landia have completed nearly 10 years of service at the ROCKWOOL® manufacturing plant near Bridgend in South Wales, where stone wool is produced at the company’s state-of- the-art line and packaging facility. Rockwool is the world’s largest producer of stone wool insulation and the second largest insulation producer globally.

The stone wool at Bridgend is filtered from the collected process water, as ROCKWOOL’s Maintenance Manager, Jeff Thomas, explains:

“The stone wool manufacturing process resembles a giant candy floss machine, with Landia’s mixers keeping the dust in suspension, whilst the chopper pumps then send the wastewater away”.

Serving two production lines, Landia’s 7.5 kW DG chopper pumps and 2.2 kW 300 rpm POP-I mixers are located in a reclamation unit underneath two large towers, reclaiming every last speck of dust and drop of water.

He added: “We make and supply a full range of smart and sustainable insulation products for the construction industry, based on innovative stone wool technology, so we don’t want breakdowns and downtime. The Landia equipment has always worked fine and been very reliable in what is a very tough application, especially for pumps”.

Makers of the world’s first chopper pump back in 1950, Landia has developed a unique chopping system of fixed and rotating hardened steel cutters that prevent the potential damage that would burden weaker pumps.
