In April 2005 Gorman-Rupp purchased the Wallwin range of submersible and dry well submersible pumps from Gilkes. These are now known as the Gorman-Rupp JW Series. The pumps are designed to meet the specifications of water companies for sludge and sewage applications. Various types of impeller are available to best suit the application. These include channel, vortex and screw types. It is the intention of Gorman-Rupp to further develop this already popular and reputable range of pumps.
