Pump retrofitting: New Lease of Life for Old Pumps

For all of the dedication of a mine’s service staff to the recommended greatest follow 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, component put on inhibits pump efficiency. เกจ์วัดแรงดันแก๊ส is at that point the place, timeously, mines might have to noticeably think about retrofitting as a possible option.
A rational business determination
In this surroundings, the place costs of capital gear costs are increasing, 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 enterprise decision: “Retrofitting is an excellent different to buying a brand new product and could be performed on pumps no matter their supposed use. It is equally appropriate for industrial, water supply and waste water disposal functions as well as for the facility supply business.”
It is simply natural for mine operators to ponder acquiring new pumps. New pump fashions meet contemporary necessities like improved vitality effectivity, compliance with new legal requirements (relating to emissions and safety), prolonged service life and technology which produces operating knowledge. But this will likely not necessitate replacing an old pump mannequin, KSB Pumps says, as retrofitting could give an old pump a new lease of life, particularly in the following ways:
Save maintenance costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with legal requirements (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 beyond modifications to the supplies.
Hydraulic modifications
Some of the hydraulic modifications may involve:
Remachining of present impellers
Installation of new impellers for off-design situations
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 modifications:
Closed bearing brackets improve the smoothness of operation and prolong the bearing life
Installation of mechanical seal methods
Employment of mobile surface put on rings to enhance efficiency, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its a few 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, cover and casing – to be used with finely dispersed, extremely abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
