Pump retrofitting: New Lease of Life for Old Pumps

For all the dedication of a mine’s service staff to the really helpful best practice in pump management, someday, encountering circumstances of pump element wear and tear is inevitable – a matter of when and never if. And when it does occur, part put on inhibits pump efficiency. It is at that time the place, timeously, mines might have to seriously consider retrofitting as a possible choice.
A rational business choice
In this surroundings, where costs of capital tools prices are growing, substitute may be a sensible enterprise decision. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise choice: “Retrofitting is a superb various to buying a new product and may be performed on pumps no matter their meant use. digital pressure gauge ราคา is equally appropriate for industrial, water supply and waste water disposal functions as properly as for the ability supply business.”
It is just natural for mine operators to ponder buying new pumps. New pump models meet contemporary requirements like improved power effectivity, compliance with new legal necessities (relating to emissions and safety), extended service life and know-how which produces working knowledge. But this will not necessitate replacing an old pump model, KSB Pumps says, as retrofitting may give an old pump a new lease of life, particularly in the following methods:
Save upkeep costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with authorized requirements (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 supplies.
Hydraulic modifications
Some of the hydraulic modifications might contain:
Remachining of present impellers
Installation of latest impellers for off-design conditions
Optimisation of volute casing for off-design circumstances
Adjustment of the variety of stages (on multistage pumps)
Mechanical adjustments
The following are some of the mechanical adjustments:
Closed bearing brackets improve the smoothness of operation and lengthen the bearing life
Installation of mechanical seal methods
Employment of cellular surface put on rings to enhance efficiency, rotor dynamics and dry working properties
Use of optimised materials
The following are its a number of the materials that a variety of the optimised materials that may be used:
Super duplex chrome steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cowl and casing – to be used with finely dispersed, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
