Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service team to the recommended finest follow in pump administration, someday, encountering circumstances of pump element put on 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 could have to noticeably consider retrofitting as a feasible possibility.
A rational enterprise choice
In this setting, the place prices of capital tools costs are rising, replacement may be a sensible business determination. In weksler pressure gauge ราคา focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is a superb alternative to buying a model new product and may be performed on pumps regardless of their intended use. It is equally suitable for industrial, water provide and waste water disposal functions in addition to for the facility supply industry.”
It is only pure for mine operators to ponder acquiring new pumps. New pump models meet modern necessities like improved vitality effectivity, compliance with new legal necessities (relating to emissions and safety), extended service life and know-how which produces working data. But this will likely not necessitate changing an previous pump model, KSB Pumps says, as retrofitting may give an outdated pump a brand new lease of life, specifically in the following ways:
Save maintenance costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with legal necessities (e.g: TA-Luft, ATEX)
READ: Full-service capability important for reliable pump provide
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and beyond adjustments to the materials.
Hydraulic modifications
Some of the hydraulic modifications may contain:
Remachining of existing impellers
Installation of latest impellers for off-design situations
Optimisation of volute casing for off-design conditions
Adjustment of the variety of phases (on multistage pumps)
Mechanical adjustments
The following are a variety of the mechanical adjustments:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life
Installation of mechanical seal techniques
Employment of cellular surface wear rings to enhance efficiency, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its a variety of the materials that a few of the optimised supplies that could be used:
Super duplex stainless steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cover and casing – to be used with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
