15 Nov Sealing in slurry
Slurry is a heavy consistency liquid mixture of water, soil, rock, ferrous and non-ferrous materials that can range in size from 1mm in thickness up to 25mm.
According to Raj Jadow, the National Key Account Manager at Seal Innovations, slurry pumps are often subject to the effects of corrosion, and these corrosive materials can leak onto the pump shaft and bolting assembling, causing the pump to fail.
“A leak that incurs corrosion or starts the gradual erosion process of pump wear can damage the mechanical system and impede the flow of materials,” explains Raj. “When you have a hyper saline or chemical environment, it will lead to seal corrosion. This problem can be aggravated if there’s erosion in pump parts, leading to material crystallising around sealing surfaces.”
