Typical by-pass operations would require 3 water pumps to handle the primary flow and one extra pump with 33% redundancy using an average of 450 HP for the primary pumps. MWI has developed a hydraulic submersible pump to out perform other pumps by being more efficent and cost effective by using less then the required amount. Available in electric or diesel drives, an MWI HNC20 20” system, with two pumps and drive units, requires 50% less space than conventional by-pass pump systems. This non-clog pump has 200% larger solids handling capability over conventional by-pass pumps with a flow of 20MGD, thanks to its 200 HP engine. Choose the security and effiency of two HNC 20” pumps to handle full plant by-pass with 100% redundancy and get the job done right.
