For all of the commitment of a mine’s service team to the beneficial finest apply in pump administration, someday, encountering instances of pump element put on and tear is inevitable – a matter of when and never if. And when it does happen, element wear inhibits pump performance. It is at that point where, timeously, mines could have to significantly think about retrofitting as a feasible option.
A rational enterprise choice
In this environment, the place prices of capital equipment costs are increasing, substitute may be a wise enterprise decision. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business decision: “Retrofitting is a superb various to buying a brand new product and could be performed on pumps regardless of their supposed use. pressure gauge ออก หลัง is equally appropriate for industrial, water provide and waste water disposal applications as properly as for the power provide industry.”
It is only natural for mine operators to ponder acquiring new pumps. New pump fashions meet up to date requirements like improved power efficiency, compliance with new legal necessities (relating to emissions and safety), extended service life and technology which produces working information. But this may not necessitate changing an outdated pump model, KSB Pumps says, as retrofitting might give an old pump a new lease of life, specifically within the following ways:
Save upkeep prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with authorized necessities (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 past modifications to the materials.
Hydraulic modifications
Some of the hydraulic modifications might involve:
Remachining of existing impellers
Installation of recent impellers for off-design situations
Optimisation of volute casing for off-design conditions
Adjustment of the number of stages (on multistage pumps)
Mechanical adjustments
The following are some of the mechanical adjustments:
Closed bearing brackets improve the smoothness of operation and lengthen the bearing life
Installation of mechanical seal techniques
Employment of cellular surface put on rings to enhance efficiency, rotor dynamics and dry operating properties
Use of optimised materials
The following are its a variety of the supplies that some of the optimised materials that may be used:
Super duplex stainless steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cover and casing – to be used with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
