For all the commitment of a mine’s service group to the really helpful best apply in pump administration, someday, encountering instances of pump part wear and tear is inevitable – a matter of when and not if. And when it does occur, element wear inhibits pump efficiency. It is at that point the place, timeously, mines could have to noticeably consider retrofitting as a possible option.
A rational enterprise determination
In this environment, where costs of capital equipment costs are increasing, replacement could also be a wise business decision. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise choice: “Retrofitting is an excellent different to purchasing a brand new product and could be performed on pumps no matter their supposed use. It is equally suitable for industrial, water supply and waste water disposal purposes as nicely as for the power supply trade.”
It is only pure for mine operators to ponder acquiring new pumps. New pump models meet modern necessities like improved power effectivity, compliance with new legal requirements (relating to emissions and safety), extended service life and technology which produces working information. But this will not necessitate replacing an outdated pump mannequin, KSB Pumps says, as retrofitting may give an outdated pump a brand new lease of life, particularly within the following methods:
Save upkeep costs
Reduce power 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 supplies, above and beyond changes to the supplies.
เกจวัดแรงดันลม10bar of the hydraulic modifications might contain:
Remachining of existing impellers
Installation of latest impellers for off-design circumstances
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 modifications:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life
Installation of mechanical seal methods
Employment of mobile surface put on rings to improve efficiency, rotor dynamics and dry working properties
Use of optimised supplies
The following are its a few of the materials that a number 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, extremely abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
