Pump retrofitting: New Lease of Life for Old Pumps

For เกจ์ลมsumo of the dedication of a mine’s service group to the really helpful finest practice in pump administration, sometime, encountering circumstances of pump element put on and tear is inevitable – a matter of when and not if. And when it does occur, component put on inhibits pump performance. It is at that time the place, timeously, mines might have to noticeably consider retrofitting as a possible choice.
A rational enterprise decision
In this environment, where prices of capital tools prices are rising, replacement could additionally be a sensible business determination. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is a superb various to buying a brand new product and can be performed on pumps no matter their intended use. It is equally suitable for industrial, water provide and waste water disposal applications as well as for the ability provide trade.”
It is only pure for mine operators to ponder acquiring new pumps. New pump fashions meet modern necessities like improved energy effectivity, compliance with new legal necessities (relating to emissions and safety), prolonged service life and expertise which produces operating data. But this will likely not necessitate changing an outdated pump model, KSB Pumps says, as retrofitting may give an outdated pump a model new lease of life, particularly within the following methods:
Save maintenance costs
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with authorized requirements (e.g: TA-Luft, ATEX)
READ: Full-service functionality important for dependable pump provide
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the supplies, above and past modifications to the supplies.
Hydraulic modifications
Some of the hydraulic modifications might contain:
Remachining of current impellers
Installation of recent impellers for off-design situations
Optimisation of volute casing for off-design conditions
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 prolong the bearing life
Installation of mechanical seal systems
Employment of mobile floor wear rings to enhance effectivity, rotor dynamics and dry running properties
Use of optimised supplies
The following are its a few of the supplies that a variety of the optimised materials that might be used:
Super duplex stainless-steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cowl and casing – to be used with finely dispersed, highly abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
