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.

U slučaju abrazivnog i korozivnog korišćenja, u nekim komponentama može doći do prirodnog habanja. U pogledu gornje primene do habanja može doći pre svega kod rotora, agitatora, usisne ploče, rukavca vratila, uljanog prstena, mehaničke zaptivke, kućišta pumpe, sita, kućišta motora i ispusne spojnice. Radni vek ovih delova može znatno da varira zavisno od radnih uslova i može biti kraći od garantnog perioda.
U tom smislu obratite pažnju na naše opšte uslove korišćenja koje vam takođe na zahtev šaljemo poštom.
