The vertical monoblock multistage electric pumps of the series Tech J Sub are designed with the most advanced and sophisticated engineering and industrial design systems. They have been studied to pump clean liquids, without abrasives and suspended solids, non- explosive or aggressive for the pump’s materials. 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.
