Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service team to the beneficial greatest apply in pump administration, sometime, encountering cases of pump part put on and tear is inevitable – a matter of when and not if. And when it does happen, part wear inhibits pump efficiency. It is at that point where, timeously, mines could have to significantly think about retrofitting as a possible option.
A rational enterprise determination
In this environment, where costs of capital gear prices are growing, alternative could also be a smart enterprise decision. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise choice: “Retrofitting is a superb various to buying a new product and can be performed on pumps no matter their supposed use. It is equally suitable for industrial, water provide and waste water disposal applications in addition to for the ability supply industry.”
It is simply pure for mine operators to ponder acquiring new pumps. New pump models meet up to date requirements like improved energy effectivity, compliance with new legal requirements (relating to emissions and safety), prolonged service life and expertise which produces working data. But this will likely not necessitate replacing an previous pump model, KSB Pumps says, as retrofitting might give an outdated pump a model new lease of life, specifically in the following ways: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 supplies, above and past changes to the supplies.
เกจวัดแรงดันออกซิเจน of the hydraulic modifications might contain:
Remachining of current impellers
Installation of latest impellers for off-design situations
Optimisation of volute casing for off-design conditions
Adjustment of the number of phases (on multistage pumps)
Mechanical adjustments
The following are some of the mechanical changes:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life
Installation of mechanical seal methods
Employment of cellular surface wear rings to improve effectivity, rotor dynamics and dry working properties
Use of optimised materials
The following are its a variety of the supplies that some of the optimised materials which could be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cowl and casing – to be used with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
