Becker HS pumps delivered to platinummine in Limpopo Becker Mining SA has recently supplied five HS pumps to a new fur- nace slag granulation process plant at a platinummine in the Limpopo region. “This contract, for the manufacture of two 8x8-12 HS pumps with ‘V’ belt drives C/W 160 kW motors and three 6x6-18 HS pumps with ‘V’ belt drives C/W 90 kW motors, was delivered prior to the required delivery date,” says Rick Jacobs of Becker Mining SA. “These robust pumps have been designed for optimum efficiency, lowmaintenance and extended service life in harsh operating conditions.” Becker’s HS pump range includes four models – HS (horizontal type), VHS (vertical type), PVS (vertical type) and HTMS (submersible) pumps. These pumps are available in various sizes – from 50 mm to 203 mm units. The heavy-duty, hardened chrome iron construction (650BHN) of the wet end in the HS series significantly increases service life. These pumps have a recessed impeller that allows large abrasive materials to pass through the pump without damaging the impeller, thereby extending the pump life and service intervals due to reducing wear. The hydro solids pump range offers flexible drive arrangements – from direct drives to various V-belt drives. Units in the vertical spindle range of pumps are manufactured in different sizes with various shaft lengths to suit customer requirements.
