For all of the dedication of a mine’s service staff to the beneficial greatest practice in pump management, someday, encountering circumstances of pump part wear and tear is inevitable – a matter of when and not if. And when it does happen, component put on inhibits pump efficiency. It is at that point the place, timeously, mines may have to significantly think about retrofitting as a possible choice.
A rational enterprise choice
In this setting, the place costs of capital gear costs are increasing, substitute could also be a wise enterprise choice. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is a wonderful alternative to purchasing a model new product and may be performed on pumps regardless of their meant use. It is equally suitable for industrial, water supply and waste water disposal applications in addition to for the facility supply industry.”
เกจวัดแรงดันต่ำ is simply natural for mine operators to ponder acquiring new pumps. New pump fashions meet up to date requirements like improved power efficiency, compliance with new authorized requirements (relating to emissions and safety), prolonged service life and technology which produces working data. But this will not necessitate replacing an outdated pump model, KSB Pumps says, as retrofitting may give an old pump a new lease of life, specifically in the following ways:
Save upkeep prices
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with authorized requirements (e.g: TA-Luft, ATEX)

Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and beyond modifications to the materials.
Hydraulic modifications
Some of the hydraulic modifications could involve:
Remachining of current impellers
Installation of recent impellers for off-design situations
Optimisation of volute casing for off-design circumstances
Adjustment of the number of stages (on multistage pumps)
Mechanical adjustments
The following are a number of the mechanical changes:
Closed bearing brackets improve the smoothness of operation and prolong the bearing life
Installation of mechanical seal methods
Employment of cellular floor wear rings to enhance efficiency, rotor dynamics and dry running properties
Use of optimised materials
The following are its a number of the materials that a variety of the optimised materials which might be used:
Super duplex chrome steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cowl and casing – to be used with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
