    Pumps are usually installed inside sumps that are used to collect liquid overflow or chemical waste from industrial processes. The feature of these sumps is the variability of the liquid level contained in it: this level depends on the process and must be run by level probes that stop the pumps when the level is too low and put them in motion when the level is high. These numerous starts-stops can cause damages to the motors and pumps. The cantilever pumps are able to work dry and do not need to be stopped when the level is too low. They can work continuously without having to be run by level probes. A key feature of cantilever pump is that there no bearings or bushings submerged therefore the pump can handle liquid with solids and operate dry.
