Client: African Rainbow Minerals
Industry: Mining
Region: Mpumalanga, South Africa
Product: CS5E2, 2 units
Installation Date: 2007

Challenge

• Mines recycle process water and use some of it for Gland Service Water (GSW).
• The recycled process water may have high suspended solids levels.
• The suspended solids cause damage to equipment.
• Specifically, dirty GSW will reduce the life of the slurry pump stuffing box components and gland packing.
• The mine required an automatic, self-cleaning filter that would provide an uninterrupted supply of service water.
• The requirement was for a filter that would be fit-for-purpose in the tough, uncompromising mining environment.

Application

• Final Filtration / Gland Service Water (removal of solids to protect slurry pumps).

Solution

• Design of the Kleerflo filter is rooted in the principle of inherent simplicity:
  • no rotating parts
  • very few moving parts – no close tolerance elements
  • no electric motor
  • high quality, durable, stainless steel wedgewire screens
• Kleerflo filters are designed specifically for tough industrial applications.
• On trial 24/7/365 for more than 3 decades and still standing tall.
• Low maintenance- and running costs.
• Long uninterrupted filter runs, efficient filtration and filtrate in compliance with client acceptance standards.
• Integral processing of oversized particles – so no manual pre-screens required.
• The Mine installed 2 x Kleerflo Automatic Self-Cleaning Filters, model CS5E2, to remove suspended solids.

Results

• The efficient filtration resulted in reduced wear and tear on the gland and shaft seals, reducing maintenance costs

• In 2019 the mine again decided on Kleerflo when they needed an automatic self-cleaning filter for a new application (model CS4E2).
