Client: Platinum Mine
Industry: Mining – Final Filtration – Gland Service Water
Region: Limpopo, South Africa
Product: KFS 3E1/250/05/08
Installation Date: 2018

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.
• For this application, filtration is required on the suction side of the multi-stage pumps that supply GSW to the slurry pumps.
• Filtration on the demand side of pumps runs the risk of starving the pump of water, especially during the self-cleaning (backwash) cycle.

Application

• Final Filtration / Filtration of Gland Service Water to protect slurry pumps / installed on suction (demand) side of the multi-stage pumps that deliver the water to the slurry pumps.

Solution

• Design of the KFS 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.
• KFS filters are designed specifically for tough industrial applications.
• 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.
• KFS filters are designed to provide filtration on the suction (demand) side of high-pressure pumps without the risk of starving the pumps during self-cleaning (backwash) cycles.
• The mine installed a Kleerflo Suction Filter – model KFS 3E1/250/05/08.
• Filtration provided at 250µm.

Results

• Cleaner gland service water resulted in lower maintenance costs on the slurry pumps and a decrease in downtime.
