This robust Lutz pump tube with mechanical seal or in sealless design is suitable for pumping neutral, non-aggressive, clean, thin-bodied and slightly viscous liquids out of drums and small or large containers. The pump tube is non-lubricated, thus preventing contamination of the liquids pumped.
Structure and Function:
Lutz pump tubes are immersible centrifugal pumps. The drive shaft of this pump tube is not sealed. The bearing housing unit above the impeller is designed to prevent pumped liquid from rising between the shaft and the inner tube. This device guides the liquid which penetrates between the drive shaft and the shaft bearing back into the container being drained. It is so designed that it can run dry.
