MILL CIRCUIT PUMPS

1-6.png

P-Range Carbon Transfer Pumps

Carbon Transfer range is designed specifically for slurries with large or fragile particles. The pump’s recessed impeller induces a vortex inside the chrome iron casing effectuating the pumping of extremely ‘soft’ particles that are susceptible to degradation and attrition.

The vortex inside transfers energy to the fluid without the need for pumped slurry to pass through the impeller vanes thus preserving its structure.

H-Range

Heavy Duty Elastomer and Hard Iron Liner end suction pumps. This efficient and robust yet surprisingly simple design makes it easy to maintain while having the lowest cost of ownership.

Used widely in mining and mineral processing applications and especially in rugged mill discharge. Slow running pumps have easily replaceable elastomer or hard metal liners and impellers. With various natural or synthetic elastomer or chrome iron metallurgies available for choosing the best corrosion resistant chemical process pump available. Used to pump silica sand and coarse gravel while being easy to maintain.

Applications include coal wash, mill discharge, concentrator, tailings, sugar processing, steel mills and cement processing.

Available in sizes from 25mm to 350mm discharge and covering an impressive flow range from 4 to 800 l/s. Able to generate 90m of head in a single pump with volute capable of withstanding 2100kPa. The high-pressure capability allows the user to operate several pumps in series all consolidated into one pump house, saving the expense of supporting systems like gland water supply systems.

These efficient rugged pumps are fully customizable to your process requirements with shaft seal and material selections tailored to your needs. They are ideal for series pumping applications with an optional expeller seal.

  • Multi-stage high pressure operation to 1000psi
    (6,900 kPa)
  • Heavy duty construction with through-bolt
    design provides ease of maintenance and
    minimal downtime
  • Large diameter, slow turning, high efficiency impellers designed to achieve maximum wear life and low operating costs
  • Large open internal passages reduce internal velocities and maximise wear life which lower operating costs.
  • Abrasion-resistant elastomers or alloy interchangeable bolt-in liners provide superior life and reduce overall maintenance costs.
  • Minimal shaft/impeller overhang reduces shaft deflection and increases packing life
  • Size range (discharge): 4” to 16” (100mm to 400mm)
  • Capacity up to 22,000 gpm (5,000 m3/hr)
  • Pressure up to 240ft (73m)
  • Serial arrangements whereby volutes can withstand pressures of up to 1,000 psi (6,900 kPa)

VS Range

Heavy Duty Hard Metal or Elastomer – This has been enhanced from the original design with the hydro-dynamic expeller labyrinth seal which when operating pressurizes and keeps contaminants from entering the bearings. 

  • Due to the OEM design weaknesses, we introduced our design improvements that have increased the working life of this pump significantly resulting in huge cost savings.
  • A PRZ Hydro-dynamic expeller labyrinth seal was introduced, the pressurized seal design keeps contaminants from entering the bearings with an additional shrink-on securing ring.
  • A heavy-duty five-foot column extension design for additional support.
  • A standard heavy-duty five-foot volute design to match.
  • The cantilever shaft design together with improved material selection enables high impact resistance from large pumped objects.
  • A complete test and Case study was conducted and concluded by a Mining Company quality department.
  • Monthly operating expense’s and improved overall cost of ownership have been achieved.

eDart C-TECH Knife Gate Valve

  • A case study was done on a 400mm nb Pinch Valve that was put on trial at Sibanye Stillwater’s Dam 20 re-mining site.
  • The purpose of the trial was to test if the Red Roc pinch valve would operate successfully for a duration of a six month period. If that trial is successful then Sibanye Stillwater would consider using the Red Roc pinch valve in similar applications.
  • After six months of use the valve was standing up well to its environment and it has not been necessary to remove it from the line since the installation.
  • The Red Roc Pinch Valve has performed as it should and as a result, Sibanye Stillwater has installed another four valves on that site.

A case study was completed on a 400mm NB Pinch Valve that was trialed at Sibanye Stillwater’s Dam 20 re-mining site. The purpose of the trial was to test if the Red Roc pinch valve would operate successfully for a duration of six months. Upon the successful completion of that trial Sibanye Stillwater would consider using the Red-Roc pinch valve in similar applications. After six months the valve stood up well to the harsh operating conditions it was subjected to and it was not necessary to remove it from the line for maintenance. Sibanye Stillwater has installed another four valves on that site.
