Pump retrofitting: New Lease of Life for Old Pumps

For pressure gauge น้ำมัน of the commitment of a mine’s service group to the beneficial greatest practice in pump administration, someday, encountering cases of pump component put on and tear is inevitable – a matter of when and not if. And when it does occur, component wear inhibits pump performance. It is at that point the place, timeously, mines may have to seriously contemplate retrofitting as a possible possibility.
A rational enterprise choice
In this environment, where prices of capital equipment prices are growing, alternative may be a wise business choice. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business decision: “Retrofitting is a wonderful various to buying a new product and can be carried out on pumps no matter their supposed use. It is equally suitable for industrial, water supply and waste water disposal functions as well as for the power provide trade.”
It is only natural for mine operators to ponder acquiring new pumps. New pump models meet up to date necessities like improved power effectivity, compliance with new authorized necessities (relating to emissions and safety), prolonged service life and technology which produces working knowledge. But this may not necessitate changing an previous pump model, KSB Pumps says, as retrofitting might give an previous pump a brand new lease of life, specifically within the following methods:
Save upkeep prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with legal requirements (e.g: TA-Luft, ATEX)
READ: Full-service capability vital for dependable pump provide
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and beyond modifications to the supplies.
Hydraulic modifications
Some of the hydraulic modifications might involve:
Remachining of present 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 a few of the mechanical adjustments:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life
Installation of mechanical seal methods
Employment of mobile surface wear rings to improve effectivity, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its some of the materials that a few of the optimised supplies that might be used:
Super duplex stainless steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cowl and casing – to be used with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
