For all of the dedication of a mine’s service team to the really helpful best practice in pump management, someday, encountering cases of pump component put on and tear is inevitable – a matter of when and not if. And when it does happen, part put on inhibits pump performance. It is at that time where, timeously, mines could have to significantly contemplate retrofitting as a possible possibility.
A rational business determination
In this surroundings, where costs of capital tools prices are rising, alternative may be a wise business determination. In เกจวัดแรงดันปั๊มลมpuma at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is a superb alternative to purchasing a model new product and may be carried out on pumps no matter their supposed use. It is equally appropriate for industrial, water supply and waste water disposal applications in addition to for the facility provide trade.”
It is only natural for mine operators to contemplate acquiring new pumps. New pump models meet up to date necessities like improved energy effectivity, compliance with new authorized necessities (relating to emissions and safety), prolonged service life and technology which produces working information. But this will not necessitate replacing an previous pump model, KSB Pumps says, as retrofitting might give an outdated pump a brand new lease of life, specifically in the following methods:
Save upkeep prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with authorized 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 changes to the materials.
Hydraulic modifications
Some of the hydraulic modifications could involve:
Remachining of current impellers
Installation of new impellers for off-design conditions
Optimisation of volute casing for off-design conditions
Adjustment of the number of levels (on multistage pumps)
Mechanical changes
The following are a few of the mechanical modifications:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life
Installation of mechanical seal methods
Employment of cellular surface put on rings to enhance effectivity, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its a few of the supplies that a variety of the optimised supplies which may 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, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
