Pumping Bentonite

Images

A Hungarian company was looking for a solution to pump bentonite in a deep construction site. Initially, high-speed pumps were used, but they did not deliver the desired performance.

The solution finally came with Tsurumi slow-speed pumps connected in series in a booster installation: The KRS2-150 is excellent for this abrasive application because it operates with fewer revolutions. The series connection provides the necessary power to pump the abrasive liquid over the required distance without any problems.

In a test installation, it was checked whether the solution actually worked in practice. The water containing bentonite was fed from a container about five metres up into the booster pump. It then pumped it through a 400-metre-long pipeline to the separation plant. The solution worked so well that the customer will now standardise this Tsurumi application.

Specifications KRS2


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.
