The CentraBLAST self filtering pump has an innovative design that can filter ground glass, cast aluminum, cast iron and other composites to 5 microns and below. It can be used alone or with a bag filter, increasing the bag filter’s life up to 20 times! The dirty coolant enters the pump housing and our uniquely designed impeller, spinning at 3400 RPM, forces the coolant out and down. Centrifugal force keeps the particulates rotating on the outside of the filter housing. The filtered coolant returns to the machine free of particulates. The particulates drop out and are collected in the re-circulation area. The particulate slurry exits the pump and is discarded as waste. With the CentraBLAST, even small contaminants, such as glass with a density of 2.7, can be filtered from coolant. When you install a CentraBLAST, you will normally only change your filter bag 3x per month, using only one hour per month with a reduction of down time and cost. CentraBLAST can handle your worst filtration problems with ease. You will save time and money by installing one today!
