SA Pumps for DRC gold mine

APE Pumps has completed manufacture of two vertical turbine pumps for return water duty at Namoya gold mine, Democratic Republic of Congo.

The pumps have been shipped, and will be installed to transfer water for re-use within the mine’s gravity circuit, a pre-leaching process that will recover coarse gold by making use of its relatively high specific gravity. After use, process water will pass into a large polyurethane lined dam for transfer by the APE vertical turbine pumps back to the start of the circuit.

Namoya is a new mine situated at the southern end of the Twangiza-Namoya gold belt in the DRC’s Maniema province approximately 225kms southwest of Bukavu. Canada’s Banro Corporation owns it.

Construction of the gravity circuit at Namoya is nearing completion as part of a larger overall mine development programme being executed by MDM Engineering. The first gold delivered by this process expected before year-end, with commercial production at the mine scheduled for early 2014.

APE’s two vertical turbine pumps for Namoya are identical machines, each eight metres in length from mounting plate to suction bell, and incorporating a water flush to lubricate the bearings.   The pumps are designed to transfer water at a flow rate of 100m3.h and a pressure of 120m.  Power will be supplied by 55kW Weg electric motors.

Namoya’s twin machines bring to 18 the number of pumps of various design supplied by APE Pumps to MDM Engineering since January 2012.

These orders have together been worth some R8m to APE Pumps, with the Namoya pumps making up approximately R1m of the total. Competition for the latest order came from manufacturers in China and India, as well as from other South African pump manufacturers.

APE Pumps dispatched the Namoya pumps from its Wadeville works towards the end of July.  They will be shipped up the African coast to Mombasa, from where they will be transported by road to Namoya.
