For all the commitment of a mine’s service team to the really helpful greatest apply in pump management, sometime, encountering cases of pump part put on and tear is inevitable – a matter of when and never if. And when it does occur, part put on inhibits pump efficiency. It is at that point the place, timeously, mines might have to seriously contemplate retrofitting as a feasible possibility.

In this environment, the place costs of capital gear costs are growing, alternative may be a wise enterprise choice. In an advisory targeted at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is a superb various to buying a new product and could be performed on pumps regardless of their meant use. It is equally suitable for industrial, water supply and waste water disposal purposes in addition to for the facility supply business.”
It is simply pure for mine operators to ponder buying new pumps. New pump fashions meet up to date requirements like improved energy effectivity, compliance with new authorized requirements (relating to emissions and safety), prolonged service life and know-how which produces operating information. But this will likely not necessitate replacing an old pump model, KSB Pumps says, as retrofitting might give an outdated pump a new lease of life, specifically within the following ways:
Save upkeep costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with legal necessities (e.g: TA-Luft, ATEX)
READ: Full-service capability vital for reliable pump supply
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the supplies, above and past changes to the supplies.
Hydraulic modifications
Some of the hydraulic modifications may involve:
Remachining of existing impellers
Installation of new impellers for off-design conditions
Optimisation of volute casing for off-design situations
Adjustment of the variety of stages (on multistage pumps)
Mechanical adjustments
The following are a few of the mechanical adjustments:
Closed bearing brackets improve the smoothness of operation and prolong the bearing life
Installation of mechanical seal techniques
Employment of mobile floor wear rings to enhance effectivity, rotor dynamics and dry working properties
Use of optimised materials
The following are its some of the supplies that a few of the optimised supplies that might be used:
Super duplex chrome steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cowl and casing – for use with finely dispersed, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
