Pump retrofitting: New Lease of Life for Old Pumps

For all the commitment of a mine’s service group to the recommended greatest apply in pump administration, someday, encountering cases of pump component put on and tear is inevitable – a matter of when and never if. And when it does happen, component wear inhibits pump performance. It is at that time the place, timeously, mines could have to significantly think about retrofitting as a feasible possibility.
A rational business determination
In this environment, the place prices of capital tools prices are increasing, replacement may be a wise business determination. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business decision: “Retrofitting is a wonderful various to buying a new product and may be performed on pumps no matter their intended use. เกจวัดแรงดันน้ำ10บาร์ is equally suitable for industrial, water supply and waste water disposal purposes in addition to for the ability supply trade.”
It is simply pure for mine operators to contemplate acquiring new pumps. New pump models meet modern requirements like improved vitality efficiency, compliance with new legal necessities (relating to emissions and safety), extended service life and know-how which produces operating knowledge. But this may not necessitate changing an previous pump model, KSB Pumps says, as retrofitting might give an outdated pump a new lease of life, specifically in the following methods:
Save upkeep prices
Reduce energy consumption
Achieve longer service life
Increase system availability
Comply with authorized necessities (e.g: TA-Luft, ATEX)
READ: Full-service capability vital for reliable pump supply
Core areas in Retrofitting
The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and past adjustments to the materials.
Hydraulic modifications
Some of the hydraulic modifications might involve:
Remachining of existing impellers
Installation of new impellers for off-design situations
Optimisation of volute casing for off-design situations
Adjustment of the number of levels (on multistage pumps)
Mechanical changes
The following are some of the mechanical modifications:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life
Installation of mechanical seal techniques
Employment of mobile surface put on rings to improve efficiency, rotor dynamics and dry running properties
Use of optimised materials
The following are its a variety of the supplies that a variety of the optimised supplies that may be used:
Super duplex stainless steel grades or nickel alloys
Ceramic mineral castings for impellers, wear plates, cover and casing – to be used with finely dispersed, extremely abrasive options
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
