For all of the dedication of a mine’s service staff to the really helpful best apply in pump management, someday, encountering cases of pump part wear and tear is inevitable – a matter of when and not if. And when it does occur, element wear inhibits pump performance. It is at that point where, timeously, mines could have to significantly consider retrofitting as a feasible choice.
A rational enterprise determination
In this environment, the place prices of capital gear costs are rising, replacement may be a sensible business determination. In an advisory targeted at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is a wonderful different to buying a new product and can be performed on pumps regardless of their intended use. เครื่องมือที่ใช้วัดความดัน is equally suitable for industrial, water provide and waste water disposal applications as nicely as for the power provide trade.”
It is simply natural for mine operators to contemplate buying new pumps. New pump models meet modern necessities like improved power effectivity, compliance with new legal requirements (relating to emissions and safety), prolonged service life and know-how which produces operating knowledge. But this will likely not necessitate replacing an outdated pump mannequin, KSB Pumps says, as retrofitting could give an previous pump a new lease of life, specifically in the following ways:
Save upkeep prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with legal 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 materials.
Hydraulic modifications
Some of the hydraulic modifications may involve:
Remachining of present impellers
Installation of new 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 few of the mechanical adjustments:
Closed bearing brackets improve the smoothness of operation and lengthen the bearing life
Installation of mechanical seal methods
Employment of mobile floor put on rings to improve efficiency, rotor dynamics and dry running properties
Use of optimised materials
The following are its a number of the supplies that a variety of the optimised supplies that might be used:
Super duplex stainless steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cover and casing – to be used with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
