Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service group to the really helpful finest apply in pump management, sometime, encountering circumstances of pump component wear and tear is inevitable – a matter of when and never if. And when it does occur, part wear inhibits pump performance. เกจวัดอาร์กอน is at that time the place, timeously, mines may have to seriously think about retrofitting as a possible possibility.
A rational business choice
In this surroundings, where prices of capital gear costs are rising, substitute could additionally be a smart enterprise determination. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise determination: “Retrofitting is a wonderful alternative to buying a 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 applications as well as for the power supply industry.”
It is just pure for mine operators to ponder acquiring new pumps. New pump fashions meet contemporary necessities like improved vitality effectivity, compliance with new legal necessities (relating to emissions and safety), extended service life and know-how which produces working knowledge. But this will likely not necessitate changing an previous pump model, KSB Pumps says, as retrofitting might give an previous pump a brand new lease of life, particularly 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 materials, above and past adjustments to the materials.
Hydraulic modifications
Some of the hydraulic modifications may involve:
Remachining of existing impellers
Installation of latest impellers for off-design circumstances
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 modifications:
Closed bearing brackets improve the smoothness of operation and prolong the bearing life
Installation of mechanical seal techniques
Employment of cellular floor put on rings to improve effectivity, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its some of the materials that a number of the optimised materials that may be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cowl and casing – for use with finely dispersed, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
