The Project:
Extension of the L433
road Velbert/Langenberg
Executing company:
Wayss & Freytag Ing. Bau AG |
| |
|
|
|
The Problem:
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. |

|
|
 |
|
Our Solution:
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. |

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,
suction plate, shaft sleeve, oil ring and mechanical seal. 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 conditions of sales

send to you by mail on request. |
