Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service staff to the recommended greatest follow in pump management, sometime, encountering instances of pump part wear and tear is inevitable – a matter of when and not if. And when it does occur, component wear inhibits pump efficiency. It is at that point the place, timeously, mines may have to noticeably think about retrofitting as a feasible possibility.
A rational business determination
In this environment, where prices of capital equipment costs are growing, substitute may be a sensible business choice. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business decision: “Retrofitting is a superb alternative to buying a new product and can be performed on pumps no matter their meant use. It is equally appropriate for industrial, water supply and waste water disposal functions as well as for the facility supply business.”
It is simply pure for mine operators to contemplate acquiring new pumps. New pump fashions meet contemporary requirements like improved vitality efficiency, compliance with new authorized requirements (relating to emissions and safety), prolonged service life and expertise which produces operating information. But this will likely not necessitate replacing an previous pump model, KSB Pumps says, as retrofitting could give an previous pump a brand new lease of life, specifically in the following methods:
Save maintenance prices
Reduce power 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 changes to the materials.
ส่วนประกอบpressuregauge of the hydraulic modifications may contain:
Remachining of present impellers
Installation of latest impellers for off-design circumstances
Optimisation of volute casing for off-design conditions
Adjustment of the variety of stages (on multistage pumps)
Mechanical changes
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 systems
Employment of mobile surface put on rings to enhance effectivity, rotor dynamics and dry working properties
Use of optimised supplies
The following are its a few of the supplies that some of the optimised materials that 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 solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
