The subzero-grain sludge originating from the gravel washing plant which has collected in the used water pond had to be pumped off.
By the application of a high-performance Tsurumi submersible waste water pump of Type KRS822 with an additionally attached flushing device, which was supplied with fresh water by means of a separate high-pressure pump, the settled sludge was agitated and was pumped off in a highly concentrated condition. The advantage of this type of pump is the low rotational speed of 1450 rpm affording a considerably longer service life.
