Watson-Marlow Bredel Pumps

Technology Benefits

There are a number of key benefits associated with using Bredel's hose pump technology in the mining sector to add value and reduce costs:

• Peristaltic hose pumps handle up to 80 percent solid slurries. Compare this to a centrifugal pump which only handles slurries with less than 30 percent solids
  
• This makes up to 71 percent less water usage compared to a centrifugal pump system.
• Smaller amounts of chemicals are needed because of the much less water used
  
• Using peristaltic hose pumps means fewer equipment consumables are necessary after thickening applications. For example, disc filter usages can be reduced by 25 percent and with each filter costing around $100,000, there are significant immediate savings
• In a peristaltic hose pump there is no mechanical seal flush water required. This is an immediate saving of approximately 72 litres of water per minute compared to centrifugal pumps. And this figure does not include any spillage from damaged seals.
  
• Less storage is required for tailings with the number of basins able to be reduced
  

Using peristaltic hose pumps can provide an overall lower environmental risk and the efficiency savings are significant.

Problems Solved

More and more mining industry customers are turning to Bredel hose pump technology to provide solutions to specific challenges and problems. This is because hose pumps can help mine operators face up to key challenges:

• Reducing downtime
• Reducing operating costs
• Managing and reducing water use
• Reducing chemical usage
• Lowering maintenance costs
• Conforming to environmental regulations

Fit For Purpose

Among the many benefits of peristaltic hose pumps are:

• No mechanical seals
• No seal gland water flush systems
• No moving parts in the product zone
• Low and easy maintenance - just one wearing part; the hose
• Backflow and siphoning are prevented without the need for valves
• Wear-free performance

For the mining sector this last point is arguably the most advantageous. The longer a pump can operate without maintenance or failure, the better. The wear-free performance of peristaltic pumps is an attribute that results from a unique operating principle. Unlike other pumps, the abrasive nature of the product has no influence on pump life and the need for routine maintenance and spares is greatly reduced.
