The Dewatering Process benefits significantly from low shear pumps that do not bulk-out the sludge, greatly improving the efficiency of the dewatering process.
Every Hidrostal Pump uses a single-vane screw centrifugal impeller. Patented in 1960, it was originally designed to unload fresh fish from deep-sea trawlers without damage. The Impeller makes a long slow turn from the axial inlet to the radial outlet – providing both its low shear characteristics and impressive hydraulic performance.
