About this document
Understanding Suction Specific Speed Limits by Tasawwur Tahir is a document available to read on EtoBox.
This document discusses suction specific speed (Nss) and its impact on pump reliability and life cycle costs. It notes that while an early 1982 study found increased failure rates above Nss of 11,000, the author of that study cautioned against a single hard limit and noted pumps have improved. Modern pumps with sophisticated designs have been shown to reliably operate at higher Nss. Strict Nss limits can increase energy costs, which make up a large portion of pump life cycle costs, by requiring lower effici
