The project:


Rainwater disposal in road ballast works


Executing companies:

NSN GmbH&Co.KG

Company Münchinger, Bretten


The problem:


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.


Our solution:


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.

U slučaju abrazivnih i korozivnih primjena, normalno je da će se u određenim komponentama dogoditi snažnije trošenje. S obzirom na gornju primjenu trošenje se može odvijati uglavnom u radnom kolu, miješalici, usisnoj ploči, rukavcu osovine, uljnom prstenu, mehaničkoj brtvi, kućištu pumpe, cjedilu, kućištu motora i ispusnoj spojki. Ovisno o radnim uvjetima vijek trajanja tih dijelova može značajno varirati i može biti kraći od pravnog zakonskog razdoblja.
S obzirom na to pridavajte pažnju našim općim uvjetima koje vam također šaljemo e-poštom na zahtjev.
