CONSTRUCTION FEATURES OF THE PUMP
Multistage centrifugal type with radial impellers. Pump and motor directly coupled with rigid coupling. Technopolymer impellers with stainless steel wearing parts, fitted on floating clearance rings made of synthetic low abrasion material, and technopolymer diffusers that impart significant wear resistance to the pump. Pump liner, shaft and coupling in stainless steel. Base support (with built-in filter) and upper head (with built-in check valve) in technopolymer. Plastic cable sheath. The pumps comply with the European Community Directives.
