Pump retrofitting: New Lease of Life for Old Pumps

For all of the dedication of a mine’s service staff to the recommended greatest practice in pump management, someday, encountering instances of pump part wear 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 point the place, timeously, mines might have to noticeably think about retrofitting as a feasible possibility.
A rational business decision

In this environment, the place costs of capital equipment costs are rising, replacement may be a sensible business decision. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise decision: “Retrofitting is an excellent different to buying a brand new product and can be carried out on pumps no matter their supposed use. It is equally suitable for industrial, water provide and waste water disposal applications in addition to for the ability provide industry.”

It is only pure for mine operators to ponder buying new pumps. New pump models meet contemporary necessities like improved energy efficiency, compliance with new authorized necessities (relating to emissions and safety), prolonged service life and know-how which produces operating data. But this will not necessitate replacing an previous pump model, KSB Pumps says, as retrofitting might give an outdated pump a brand new lease of life, particularly within the following ways:
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 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 changes to the supplies.
เกจวัดแรงดันดิจิตอล of the hydraulic modifications might contain:
Remachining of existing 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 changes:
Closed bearing brackets enhance the smoothness of operation and extend the bearing life

Installation of mechanical seal techniques

Employment of cellular surface put on rings to enhance effectivity, rotor dynamics and dry running properties

Use of optimised supplies

The following are its some of the materials that a number of the optimised materials that could be used:
Super duplex chrome steel grades or nickel alloys

Ceramic mineral castings for impellers, wear plates, cowl and casing – for use with finely dispersed, extremely abrasive options

Non-metallic rings and bushes

Ceramic plain bearings

Surface coatings
