An integrated project in Kazakhstan

Sever Minerals installed and put into operation two mobile quarry dewatering pumping stations at the site operated by Bakyrchik Mining Venture.

Bakyrchik Mining Venture is part of the Polymetal Group of Companies. Sever Minerals has been cooperating with this customer since the company opened its branch in Kazakhstan. Recently, the client has come up with an ambitious task: to install two pumping stations in the quarry in order to pump groundwater from the bottom of the quarry and lift it up to the level of almost 200 meters.

Sever Minerals experts created a fundamentally new commercially viable engineering solution that made us stand out from our competitors. In the proposal, the specialists utilized both electric and diesel pumping stations, sought by the customer. The deal provides for a full range of works, from design to commissioning of the completed stations. The customer opted to assemble the equipment itself, and the stations are ready for installation.

This project is characterized by an unconventional solution, a diesel-driven equipment, requested by the client from the very start. As a basis, we took Wilo water pumps, which have proven themselves well in various projects. Sever Minerals has provided a carefully verified solution in terms of process automation: the diesel pumping station can be moved quickly to a safe area during explosions that occur every 2-3 hours, with no production losses, and then it can start pumping out the quarry water again. The mobile pumping stations are interconnected: one station provides control over the other due to unique engineering solutions.

Each of the pumping stations has a head of 200 meters, ensuring an increase in performance up to 500 m3 per hour and covering a large area of 400 meters. Earlier, Russian-made pumps were installed at the quarry, pumping only 183 m3 of quarry water per hour with a head of 383 meters.
