Surface suction removal, Wallenhorst, Germany

The Project:

Suction removal of foam and floating dirt particles from the surface of the clarification basin

Company involved:

Clarification Plant of Wallenhorst Municipality

Dealers: Vernhold Baumaschinen, Osnabrück

Tsurumi supervisor: Mr. Jürgen Rohring (Regional Sales Director, Construction, North Rhine Westphalia)

The Problem:

Surface suction removal by means of a pump, avoiding dry running and prospecting mode operation. The permanently installed pumps frequently break down due to motor damage.

The Solution:

Use of a surface suction unit, type 8-FSP. Suspending the pump from a float meant that the water level could be matched easily. Optimum suction performance was achieved by using the Venturi principle (Operation via bypass). The 8-FSP only works

for a few hours a day, which makes it considerably more efficient than the previous solution.

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.
