Rainwater disposal in road ballast works
Company Münchinger, Bretten
Disposal of rainwater with sand and dirt content, height differential of 50 metres.Cleaning of the exit with the water that is pumped off. Maintenance and repair of the pump used in the past was costly in both money and time.
After careful evaluation, it was decided to employ a TSURUMI LH311W running at 11 kW. The LH-W pumps have a high delivery pressure and can withstand sand, so wear is reduced. A KTZ47.5 at 7,5kW is employed additionally for cleaning HGVs.
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.
