Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service team to the beneficial best apply in pump administration, someday, encountering instances of pump part put on and tear is inevitable – a matter of when and never if. And when it does happen, component put on inhibits pump efficiency. It is at that time where, timeously, mines might have to seriously think about retrofitting as a possible choice.
A rational enterprise choice
In this setting, the place prices of capital gear prices are growing, replacement could additionally be a sensible enterprise decision. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business decision: “Retrofitting is an excellent various to buying a new product and can be carried out on pumps no matter their supposed use. It is equally suitable for industrial, water supply and waste water disposal purposes as well as for the facility provide industry.”
It is just natural for mine operators to ponder buying new pumps. New pump fashions meet modern requirements like improved energy effectivity, compliance with new legal requirements (relating to emissions and safety), prolonged service life and know-how which produces operating information. But this will not necessitate changing an outdated pump mannequin, KSB Pumps says, as retrofitting might give an previous pump a new lease of life, particularly within the following methods:
Save upkeep prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with legal necessities (e.g: TA-Luft, ATEX)
READ: Full-service functionality very important for dependable pump supply
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.
เกจวัดแก๊ส of the hydraulic modifications might contain:
Remachining of present impellers
Installation of new impellers for off-design conditions
Optimisation of volute casing for off-design conditions
Adjustment of the variety of levels (on multistage pumps)
Mechanical changes
The following are some of the mechanical modifications:
Closed bearing brackets enhance the smoothness of operation and lengthen the bearing life
Installation of mechanical seal methods
Employment of mobile floor put on 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 few of the optimised materials that could be used:
Super duplex chrome steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cover and casing – for use with finely dispersed, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
