Pumping off or drainage of the arising ground water containing sand during pipe heading by open dewatering.
The arising ground water is pumped off with a KRS-69 pump, including all the sand contained. A 24-h on snore mode operation must be ensured.
In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
In this regard, please pay attention to our general terms and conditions that we also send to you by mail on request.
