Applications
The pump tube RE-88 PP and RE-88 SS is designed to be used where drums or other containers have to be completely drained. The relatively small pump tube diameter of 41 mm also makes the unit ideal for use in narrow-necked containers or in drums with a 2" bunghole. 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 is sealed by a single- acting mechanical seal (MS) above the impeller, making a robust sealing system. The pump tube must not be allowed to run dry.
