A sawmill in Arkansas that produces lumber from southern yellow pine has turned to stainless steel shredder pumps for its kilns used to dry the wood to a moisture content of 8 to 18 percent.
The self-priming centrifugal pumps previously utilized were easily clogged and had to be replaced every two months or so, says the mill. Stainless steel shredder pumps were chosen as replacements for several reasons. First, the stainless steel can handle the acidic water. Second, the pump’s shredding action can process and clear out the pieces of wood and other particles. These particular pumps also have nonclog, single-vane impellers designed for high volume.
