Pump retrofitting: New Lease of Life for Old Pumps

For pressure gauge แบบ น้ำมัน of a mine’s service staff to the really helpful best follow in pump administration, sometime, encountering circumstances of pump element wear and tear is inevitable – a matter of when and never if. And when it does happen, component wear inhibits pump efficiency. It is at that time the place, timeously, mines may have to significantly consider retrofitting as a possible choice.
A rational enterprise decision
In this surroundings, the place prices of capital gear costs are growing, replacement could additionally be a sensible business decision. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise decision: “Retrofitting is an excellent alternative to purchasing a brand new product and may be carried out on pumps regardless of their intended use. It is equally appropriate for industrial, water supply and waste water disposal functions in addition to for the facility supply trade.”
It is just natural for mine operators to ponder buying new pumps. New pump models meet modern necessities like improved energy effectivity, compliance with new authorized necessities (relating to emissions and safety), prolonged service life and expertise which produces operating data. But this will not necessitate replacing an old pump model, KSB Pumps says, as retrofitting may give an outdated pump a model new lease of life, specifically within the following methods:
Save upkeep prices
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with legal requirements (e.g: TA-Luft, ATEX)
READ: Full-service functionality very important for reliable pump provide
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the supplies, above and past changes to the materials.
Hydraulic modifications
Some of the hydraulic modifications might contain:
Remachining of present impellers
Installation of new impellers for off-design circumstances
Optimisation of volute casing for off-design circumstances
Adjustment of the number of stages (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 surface put on rings to enhance efficiency, rotor dynamics and dry running properties
Use of optimised materials
The following are its some of the materials that a number of the optimised materials that might 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
