Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service group to the recommended best practice in pump administration, someday, encountering instances of pump part wear and tear is inevitable – a matter of when and never if. And when it does happen, component put on inhibits pump performance. It is at that point where, timeously, mines may have to noticeably consider retrofitting as a feasible option.
A rational enterprise choice
In this surroundings, where costs of capital equipment costs are increasing, substitute may be a wise enterprise decision. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business choice: “Retrofitting is a wonderful various to purchasing a new product and may be performed on pumps regardless of their supposed use. pressure gauge weksler ราคา is equally suitable for industrial, water supply and waste water disposal functions as properly as for the facility supply business.”
It is only natural for mine operators to contemplate acquiring new pumps. New pump models meet modern requirements like improved energy efficiency, compliance with new authorized necessities (relating to emissions and safety), extended service life and expertise which produces operating data. But this may not necessitate changing an old pump model, KSB Pumps says, as retrofitting may give an old pump a new lease of life, particularly in the following ways:
Save upkeep prices
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 past adjustments to the materials.
Hydraulic modifications
Some of the hydraulic modifications might contain:
Remachining of existing impellers
Installation of recent impellers for off-design conditions
Optimisation of volute casing for off-design conditions
Adjustment of the number of levels (on multistage pumps)
Mechanical adjustments
The following are a variety of the mechanical changes:
Closed bearing brackets enhance the smoothness of operation and lengthen 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 supplies
The following are its a few of the materials that a number of the optimised materials that 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, extremely abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
