Pump retrofitting: New Lease of Life for Old Pumps

For all of the commitment of a mine’s service group to the really helpful greatest practice in pump management, sometime, encountering circumstances of pump component wear and tear is inevitable – a matter of when and never if. And when it does occur, element put on inhibits pump efficiency. It is at that point the place, timeously, mines may have to significantly think about retrofitting as a possible option.
A rational business decision
In this environment, the place prices of capital gear costs are growing, substitute could additionally be a wise enterprise determination. In an advisory targeted at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise choice: “Retrofitting is a wonderful different to buying a new product and could be performed on pumps no matter their intended use. It is equally suitable for industrial, water provide and waste water disposal functions as well as for the facility provide business.”
pressure gauge น้ำมัน is only natural for mine operators to ponder buying new pumps. New pump models meet modern necessities like improved energy efficiency, compliance with new legal requirements (relating to emissions and safety), prolonged service life and know-how which produces working knowledge. But this will likely not necessitate replacing an previous pump mannequin, KSB Pumps says, as retrofitting may give an previous pump a model new lease of life, specifically within the following methods:
Save maintenance costs
Reduce energy 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 supplies, above and beyond modifications to the materials.
pressure gauge trerice ราคา of the hydraulic modifications could contain:
Remachining of existing impellers
Installation of new impellers for off-design circumstances
Optimisation of volute casing for off-design conditions
Adjustment of the number of levels (on multistage pumps)
Mechanical adjustments
The following are a few of the mechanical adjustments:
Closed bearing brackets improve the smoothness of operation and extend the bearing life
Installation of mechanical seal methods
Employment of cellular surface wear rings to improve effectivity, rotor dynamics and dry working properties
Use of optimised materials
The following are its a few of the supplies that some of the optimised materials which could 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, extremely abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
