TECH SUB

The vertical monoblock multistage electric pumps of the series Tech Sub are designed with the most advanced and sophisticated engineering and industrial design systems. The Tech Sub have been studied to pump clean liquids, without abrasives and suspended solids, non-explosive or aggressive for the pump’s materials, with liquid temperature not higher than 35 °C for domestic use (CEI EN 60335-2-41) or 60 °C for other use. The extreme noiselessness permit the internal or external installation, immerged in to a storage tank or basin. The use of corrosion-proof materials along with the particular impeller & diffuser design make them suitable for environments with a slight presence of sand in the water. Max. immersion 15 m.
