Pump retrofitting: New Lease of Life for Old Pumps

For all the dedication of a mine’s service staff to the really helpful best apply in pump administration, sometime, encountering circumstances of pump component put on and tear is inevitable – a matter of when and not if. And when it does happen, part put on inhibits pump efficiency. 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 setting, where prices of capital tools prices are growing, substitute could also be a smart business choice. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business decision: “Retrofitting is a wonderful alternative to purchasing a new product and can be carried out on pumps no matter their intended use. It is equally appropriate for industrial, water provide and waste water disposal applications as properly as for the ability supply business.”
It is simply pure for mine operators to contemplate acquiring new pumps. เกจวัดแรงดันดิจิตอลราคา meet contemporary necessities like improved power efficiency, compliance with new legal requirements (relating to emissions and safety), prolonged service life and know-how which produces operating data. But this may not necessitate replacing an previous pump mannequin, KSB Pumps says, as retrofitting may give an outdated pump a model new lease of life, particularly in the following ways:
Save maintenance costs
Reduce power consumption
Achieve longer service life
Increase system availability
Comply with legal requirements (e.g: TA-Luft, ATEX)
READ: Full-service functionality very important 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 modifications to the materials.
Hydraulic modifications
Some of the hydraulic modifications could involve:
Remachining of current impellers
Installation of latest impellers for off-design situations
Optimisation of volute casing for off-design conditions
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 lengthen the bearing life
Installation of mechanical seal techniques
Employment of mobile floor put on rings to improve effectivity, rotor dynamics and dry operating properties
Use of optimised supplies
The following are its a variety of the supplies that some of the optimised supplies that could be used:
Super duplex stainless steel grades or nickel alloys
Ceramic mineral castings for impellers, put on plates, cowl and casing – for use with finely dispersed, highly abrasive solutions
Non-metallic rings and bushes
Ceramic plain bearings
Surface coatings
