Editor-in-Chief Elisabeth Lisican showcases a handful of features to read in the April 2017 issue of Water & Wastes Digest.
Schreiber offers open-flight and tube-mounted screw pumps. The open-flight screw pump transports liquid in a concrete trough. A non-clog pump, typically installed at a 30- or 38-degree angle, it has a variable capacity at a constant speed up to its maximum. The tube-mounted screw pump transports liquid inside a stationary tube, simplifying design and eliminating the need for grouting. The screw pumps utilize a spherical roller, self-aligning, and combination radial/thrust lower bearing with a minimum L-10 life of 100K hours.
