Design
Single- or multistage centrifugal pumps in ring-section design, single entry; for vertical and, depending on the number of stages, angled and horizontal installation; mixed flow hydraulic systems available with reduced impeller diameters; driven by submersible motors. Suction casing fitted between pump and motor, equipped with strainer to protect the pump from coarse particles in the fluid. Permissible sand content in the fluid: 50 g/m³. Pumps with non-return valve or connection branch on option
Application pump
pumping clean or slightly contaminated water in general water supply, irrigation and spray irrigation systems, lowering and maintaining ground water levels, pressure boosting, emergency water supply, as well as mines and fountains etc.
