Coppermine Yanacocha, Peru

The Project:


Minera Yanacocha is operating several gold and copper mines in Peru. The "stage 7 project" comprises the exploration of a new copper mine.


The Problem:


Pumps Plus (Denver, USA) was employed by Bechtel International Corporation to lower the ground waterj of the "stage 7 project".


Our Solution:


21 submersible contractors' pumps type GSZ-75-4, 75kW each, were used.

Ducts were drilled at an angle of 30° and lined by 1,2m dia. steel pipes. Then the pumps were mounted at special slides and lowered into the duct.

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.
