Pump retrofitting: New Lease of Life for Old Pumps

For all of the commitment of a mine’s service staff to the beneficial finest practice in pump management, someday, encountering cases of pump component wear and tear is inevitable – a matter of when and never if. And when pressure gauge ราคา ถูก does occur, component wear inhibits pump efficiency. It is at that time the place, timeously, mines might have to seriously consider retrofitting as a feasible possibility.
A rational enterprise determination
In this environment, the place prices of capital gear costs are growing, replacement could also be a smart business choice. In an advisory targeted at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is an excellent alternative to purchasing a new product and could be performed on pumps regardless of their intended use. It is equally suitable for industrial, water provide and waste water disposal purposes in addition to for the power provide industry.”
It is only pure for mine operators to ponder acquiring new pumps. New pump fashions meet up to date requirements like improved power efficiency, compliance with new legal requirements (relating to emissions and safety), extended service life and know-how which produces working data. But this will likely not necessitate replacing an outdated pump mannequin, KSB Pumps says, as retrofitting might give an previous pump a new lease of life, particularly in the following methods:
Save upkeep costs
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with authorized 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 modifications to the materials.
Hydraulic modifications
Some of the hydraulic modifications could contain:
Remachining of existing impellers
Installation of new impellers for off-design conditions
Optimisation of volute casing for off-design situations
Adjustment of the number of stages (on multistage pumps)
Mechanical adjustments
The following are a variety of the mechanical modifications:
Closed bearing brackets improve the smoothness of operation and extend the bearing life
Installation of mechanical seal methods
Employment of mobile surface put on rings to enhance effectivity, rotor dynamics and dry operating properties
Use of optimised materials
The following are its a variety of the supplies that a few of the optimised materials 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, extremely abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
