Pump retrofitting: New Lease of Life for Old Pumps

For all of the commitment of a mine’s service group to the recommended best apply in pump administration, sometime, encountering instances of pump component wear and tear is inevitable – a matter of when and not if. And when เกจวัดน้ำยาแอร์refco does occur, part put on inhibits pump performance. It is at that point the place, timeously, mines may have to noticeably think about retrofitting as a possible possibility.
A rational enterprise decision
In this surroundings, where costs of capital gear prices are growing, substitute could also be a smart enterprise determination. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise decision: “Retrofitting is an excellent various to purchasing a brand new product and can be performed on pumps regardless of their intended use. It is equally appropriate for industrial, water provide and waste water disposal applications as well as for the ability provide business.”
It is simply natural for mine operators to ponder buying new pumps. New pump models meet up to date necessities like improved energy efficiency, compliance with new authorized necessities (relating to emissions and safety), extended service life and expertise which produces operating information. But this will not necessitate replacing an previous pump mannequin, KSB Pumps says, as retrofitting might give an previous pump a new lease of life, specifically within the following methods:
Save upkeep prices
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with authorized necessities (e.g: TA-Luft, ATEX)
READ: Full-service functionality important for reliable pump supply
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and past modifications to the materials.
Hydraulic modifications
Some of the hydraulic modifications could contain:
Remachining of current impellers
Installation of latest impellers for off-design situations
Optimisation of volute casing for off-design situations
Adjustment of the number of stages (on multistage pumps)
Mechanical adjustments
The following are some of the mechanical changes:
Closed bearing brackets enhance the smoothness of operation and lengthen the bearing life
Installation of mechanical seal techniques
Employment of cellular surface put on rings to enhance effectivity, rotor dynamics and dry working properties
Use of optimised materials
The following are its a number of the supplies that a variety of the optimised materials which could be used:
Super duplex chrome steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cover and casing – to be used with finely dispersed, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
