For all the commitment of a mine’s service staff to the beneficial finest apply in pump administration, sometime, encountering cases of pump element wear and tear is inevitable – a matter of when and never if. And when it does happen, element put on inhibits pump performance. It is at that time the place, timeously, mines might have to seriously think about retrofitting as a possible possibility.
A rational business decision
In this environment, the place costs of capital tools prices are rising, replacement could also be a wise business determination. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise decision: “Retrofitting is a superb alternative to buying a brand new product and can be carried out on pumps no matter their supposed use. เกจวัดความดันน้ำ is equally appropriate for industrial, water supply and waste water disposal purposes in addition to for the power supply business.”
It is simply pure for mine operators to contemplate buying new pumps. New pump fashions meet up to date necessities like improved vitality efficiency, compliance with new authorized requirements (relating to emissions and safety), extended service life and know-how which produces working knowledge. But this will not necessitate changing an old pump model, KSB Pumps says, as retrofitting may give an old pump a new lease of life, particularly within the following methods:
Save maintenance costs
Reduce power 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 materials, above and past adjustments to the materials.
Hydraulic modifications
Some of the hydraulic modifications might contain:
Remachining of current impellers
Installation of recent impellers for off-design circumstances
Optimisation of volute casing for off-design conditions
Adjustment of the number of phases (on multistage pumps)
Mechanical adjustments
The following are some of the mechanical modifications:
Closed bearing brackets improve the smoothness of operation and lengthen the bearing life
Installation of mechanical seal techniques
Employment of cellular floor wear rings to improve efficiency, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its some of the materials 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, cowl and casing – to be used with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
