The ground water must be pumped off. Continuous truck traffic has to be ensured due to the traditional excavation by means of building machines, i.e. pollution by mud must be prevented by continuously pumping off in pumping on snore mode.
Lowering the ground water table by means of contractors' pumps of the KTZ and KTV series. Our pumps are provided with a patented oil lifter which ensures lubrication and cooling of the mechanical seal even at a minimum oil level.
Twenty-four-hour pumping on snore mode without failure has been implemented for months now due to this particular feature.
