Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service staff to the beneficial greatest apply in pump management, someday, encountering cases of pump element wear and tear is inevitable – a matter of when and never if. And when it does occur, component wear inhibits pump performance. It is at that time the place, timeously, mines could have to significantly think about retrofitting as a possible choice.
A rational business determination
In this surroundings, where prices of capital gear prices are rising, alternative may be a sensible enterprise decision. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is an excellent different to buying a model new product and may be performed on pumps regardless of their intended use. pressure gauge nuova fima ราคา is equally suitable for industrial, water supply and waste water disposal applications in addition to for the facility provide trade.”
It is simply pure for mine operators to ponder buying new pumps. New pump models meet contemporary requirements like improved energy efficiency, compliance with new legal necessities (relating to emissions and safety), extended service life and know-how which produces working data. But this may not necessitate changing an old pump model, KSB Pumps says, as retrofitting might give an previous pump a brand new lease of life, particularly in the following methods:
Save upkeep costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with legal necessities (e.g: TA-Luft, ATEX)
READ: Full-service functionality very important for reliable pump supply
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and beyond changes to the supplies.
Hydraulic modifications
Some of the hydraulic modifications could contain:
Remachining of present impellers
Installation of recent impellers for off-design circumstances
Optimisation of volute casing for off-design situations
Adjustment of the number of phases (on multistage pumps)
Mechanical changes
The following are a few of the mechanical changes:
Closed bearing brackets enhance the smoothness of operation and lengthen the bearing life
Installation of mechanical seal techniques
Employment of mobile surface wear rings to enhance effectivity, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its some of the supplies that some 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 – to be used with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
