Pump retrofitting: New Lease of Life for Old Pumps

For all the dedication of a mine’s service staff to the recommended best apply in pump administration, sometime, encountering instances of pump part wear and tear is inevitable – a matter of when and never if. And when it does occur, element put on inhibits pump performance. It is at that time where, timeously, mines could have to significantly contemplate retrofitting as a possible choice.
A rational business choice
In this environment, the place prices of capital gear costs are increasing, replacement may be a wise business decision. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is a wonderful different to purchasing a model new product and may be performed on pumps regardless of their supposed use. หลักการทำงานของเกจ์วัดแก๊ส is equally suitable for industrial, water supply and waste water disposal functions as properly as for the ability supply industry.”
ราคาเกจวัดแรงดันลม is simply pure for mine operators to ponder acquiring new pumps. New pump models meet contemporary necessities like improved vitality effectivity, compliance with new authorized necessities (relating to emissions and safety), prolonged service life and know-how which produces working data. But this may not necessitate changing an previous pump model, KSB Pumps says, as retrofitting might give an outdated pump a brand new lease of life, particularly in the following ways:
Save maintenance prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with authorized necessities (e.g: TA-Luft, ATEX)
READ: Full-service capability very 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 beyond adjustments to the supplies.
Hydraulic modifications
Some of the hydraulic modifications may contain:
Remachining of current 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 few of the mechanical modifications:
Closed bearing brackets improve the smoothness of operation and prolong the bearing life
Installation of mechanical seal systems
Employment of cellular surface wear rings to enhance efficiency, rotor dynamics and dry working properties
Use of optimised supplies
The following are its a number of the supplies that a few of the optimised materials that might be used:
Super duplex chrome steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cowl and casing – for use with finely dispersed, extremely abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
