For all the commitment of a mine’s service staff to the recommended greatest follow in pump management, someday, encountering circumstances of pump element put on and tear is inevitable – a matter of when and never if. And when it does occur, part put on inhibits pump performance. It is at that point the place, timeously, mines could have to seriously consider retrofitting as a feasible choice.
A rational enterprise determination
In this environment, the place costs of capital equipment costs are growing, substitute could additionally be a smart enterprise decision. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is a wonderful different to purchasing a model new product and can be performed on pumps no matter their intended use. It is equally suitable for industrial, water supply and waste water disposal functions as nicely as for the ability provide trade.”
It is just pure for mine operators to contemplate acquiring new pumps. New pump models meet contemporary necessities like improved power efficiency, compliance with new legal necessities (relating to emissions and safety), extended service life and know-how which produces operating knowledge. But pressure gauge digital ราคา may not necessitate changing an old pump model, KSB Pumps says, as retrofitting could give an outdated pump a model new lease of life, specifically in the following ways:
Save maintenance 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 past 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 situations
Adjustment of the number of levels (on multistage pumps)
Mechanical adjustments
The following are a number of the mechanical modifications:
Closed bearing brackets enhance the smoothness of operation and prolong the bearing life
Installation of mechanical seal methods
Employment of cellular surface wear rings to enhance efficiency, rotor dynamics and dry working properties
Use of optimised materials
The following are its a few of the materials that some 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 – for use with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
