Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service team to the recommended greatest apply in pump administration, sometime, encountering circumstances of pump element put on and tear is inevitable – a matter of when and not if. And when เกจวัดแรงดันไอน้ำ does occur, element put on inhibits pump efficiency. It is at that point where, timeously, mines might have to seriously consider retrofitting as a feasible possibility.
A rational enterprise choice
In this environment, the place costs of capital tools costs are rising, alternative may be a sensible enterprise choice. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise decision: “Retrofitting is a superb alternative to purchasing a model new product and may be performed on pumps regardless of their intended use. It is equally suitable for industrial, water supply and waste water disposal functions in addition to for the facility supply industry.”
It is just natural for mine operators to contemplate buying new pumps. New pump models meet modern necessities like improved vitality effectivity, compliance with new authorized requirements (relating to emissions and safety), prolonged service life and expertise which produces operating data. But this will likely not necessitate replacing an outdated pump model, KSB Pumps says, as retrofitting might give an outdated pump a new lease of life, specifically in the following ways:
Save maintenance costs
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 dependable pump supply
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and beyond adjustments to the supplies.
Hydraulic modifications
Some of the hydraulic modifications could contain:
Remachining of present impellers
Installation of recent impellers for off-design situations
Optimisation of volute casing for off-design circumstances
Adjustment of the variety of stages (on multistage pumps)
Mechanical changes
The following are a variety of the mechanical modifications:
Closed bearing brackets improve the smoothness of operation and extend the bearing life
Installation of mechanical seal methods
Employment of mobile surface put on rings to enhance efficiency, rotor dynamics and dry working properties
Use of optimised materials
The following are its a number of the materials that some of the optimised supplies which may be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cover and casing – for use with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
