Hydro-solids pumps for mining applications
November 2015
Valves, Actuators & Pump Control
Becker Mining South Africa’s extensive range of light, medium and heavy duty slurry pumps includes the HS range, available in vertical, horizontal and submersible configurations. These pumps are designed for optimum efficiency, low maintenance and extended service life in diverse industries, including harsh operating conditions.
The HS pumps range, manufactured locally to stringent OEM specifications, includes four different models, in various sizes – HS (horizontal hydro-solids), VHS (vertical hydro-solids), PVS (pumpmor vertical solids) and HTMS (submersible) pumps are ideally suited to many applications in mining, waste treatment, foundries and steel mills.
“These hydro-solid vortex pumps are designed to pump sludge and slurries containing large abrasive solids, trapped air and fibrous materials in heavy service industries,” says Theo Cambanis, Becker Mining South Africa. “Due to the recessed, non-clog impeller of this range, solids and fibrous materials up to 200 mm (depending on pump size) can enter the suction inlet and be expelled through the pump discharge, without damaging the impeller.
“The PVS pump has a slightly different design, with a locknut locking the impeller to the shaft. This method prevents the impeller from turning if the motor is started in the wrong rotation direction.”
HS pumps, in horizontal and vertical configurations, offer a flexible drive arrangement, including direct coupled, overhead adjustable and Z-adjustable belt drives.
HS and VHS pumps can achieve heads up to 40 m and flow capacities of 800 m³/h at 1750 rpm. Solids to 200 mm and SG’s up to 1,5 can be handled. HTMS submersible pumps have capacities to 635 m³/h and heads to 28 m at 1450 rpm, with withstand temperatures to 90°C and pressures to 1380 kPa. PVS pumps can handle solids to 75 mm and SGs up to 1,5. Heads to 20 m can be achieved at speeds from 1450 rpm and heads to 85 m at 3000 rpm.
In all models, a robust one piece casing facilitates the flow of solids and fibrous materials and an easily accessible stuffing box minimises blow-back of media around the shaft sleeve, without actual sealing contact.
The heavy duty, hardened chrome iron construction of the wet end increases service life. Since all components are locally manufactured, these pumps are readily available and a large stock holding of spares and raw materials ensures swift delivery throughout the country.
Becker Mining employs a fully integrated ISO quality management system as part of a dedicated design, manufacturing, testing and repair facility.
