Pump retrofitting: New Lease of Life for Old Pumps

For เกจวัดแรงดัน of the dedication of a mine’s service group to the beneficial finest follow in pump administration, someday, encountering cases of pump element put on and tear is inevitable – a matter of when and never if. And when it does happen, part put on inhibits pump performance. It is at that time where, timeously, mines may have to significantly consider retrofitting as a feasible possibility.
A rational business choice

In this setting, the place costs of capital gear costs are rising, alternative may be a sensible enterprise determination. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational business determination: “Retrofitting is a superb various to buying a model new product and could be performed on pumps regardless of their intended use. It is equally suitable for industrial, water provide and waste water disposal purposes in addition to for the facility supply industry.”

It is simply pure for mine operators to ponder acquiring new pumps. New pump fashions meet contemporary necessities like improved vitality effectivity, compliance with new authorized requirements (relating to emissions and safety), extended service life and technology which produces working data. But pressure gauge 10 bar will not necessitate replacing an previous pump mannequin, KSB Pumps says, as retrofitting may give an outdated pump a brand new lease of life, specifically in the following ways:
Save upkeep costs

Reduce power consumption

Achieve longer service life

Increase system availability

Comply with authorized requirements (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 beyond adjustments to the materials.
Hydraulic modifications

Some of the hydraulic modifications might contain:
Remachining of existing impellers

Installation of recent impellers for off-design circumstances

Optimisation of volute casing for off-design situations

Adjustment of the variety of stages (on multistage pumps)

Mechanical adjustments

The following are a number of the mechanical modifications:
Closed bearing brackets enhance the smoothness of operation and prolong the bearing life

Installation of mechanical seal methods

Employment of mobile floor put on rings to enhance efficiency, rotor dynamics and dry working properties

Use of optimised supplies

The following are its a few of the materials that a variety of the optimised supplies which may 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
