Submersible motor-driven pump aggregate with cooling arrangement

摘要

Submersible motor-driven pump aggregate, a cooler provided with an intermediate shaft being arranged between motor and centrifugal pump. This cooler has a cleaning device, with the aid of which deposits settling on the cooler surface can be removed. The diameter of the cooler and its cleaning device is the same as or smaller than the greatest diameter of the submersible motor-driven pump aggregate.
