For all the commitment of a mine’s service group to the beneficial finest apply in pump administration, sometime, encountering instances of pump element put on and tear is inevitable – a matter of when and not if. And when it does happen, element put on inhibits pump performance. It is at that time the place, timeously, mines might have to significantly consider retrofitting as a feasible possibility.
A rational business choice
In this setting, the place costs of capital equipment prices are rising, alternative could additionally be a smart business decision. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise determination: “Retrofitting is a wonderful different to buying a model new product and could be performed on pumps regardless of their meant use. It is equally appropriate for industrial, water supply and waste water disposal functions in addition to for the power provide industry.”
It is only natural for mine operators to contemplate acquiring new pumps. New pump fashions meet modern necessities like improved energy efficiency, compliance with new authorized necessities (relating to emissions and safety), prolonged service life and know-how which produces operating information. But pressure gauge nuova fima ราคา will not necessitate replacing an previous pump mannequin, KSB Pumps says, as retrofitting could give an outdated pump a model new lease of life, specifically in the following ways:
Save maintenance 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 materials, above and beyond modifications to the supplies.
Hydraulic modifications
Some of the hydraulic modifications could involve:
Remachining of present impellers
Installation of recent impellers for off-design situations
Optimisation of volute casing for off-design conditions
Adjustment of the number of levels (on multistage pumps)
Mechanical adjustments
The following are some of the mechanical modifications:
Closed bearing brackets improve the smoothness of operation and prolong the bearing life
Installation of mechanical seal techniques
Employment of mobile floor wear rings to improve effectivity, rotor dynamics and dry running properties
Use of optimised materials
The following are its some of the materials that a variety of the optimised materials which could be used:
Super duplex chrome steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cover and casing – to be used with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
