Pump retrofitting: New Lease of Life for Old Pumps

For เพรสเชอร์เกจ of the commitment of a mine’s service team to the really helpful finest follow in pump management, someday, encountering instances of pump element wear and tear is inevitable – a matter of when and not if. And when it does occur, component put on inhibits pump efficiency. It is at that time where, timeously, mines may have to significantly consider retrofitting as a possible choice.
A rational enterprise determination

In this surroundings, where prices of capital tools prices are increasing, replacement may be a wise enterprise choice. In an advisory targeted at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise determination: “Retrofitting is a wonderful different to buying a model new product and may be performed on pumps no matter their meant use. It is equally appropriate for industrial, water supply and waste water disposal applications in addition to for the facility supply trade.”

It is just pure for mine operators to ponder buying new pumps. New pump fashions meet modern necessities like improved energy efficiency, compliance with new legal requirements (relating to emissions and safety), prolonged service life and technology which produces working knowledge. But this may not necessitate changing an previous pump model, KSB Pumps says, as retrofitting might give an old pump a new lease of life, specifically within the following methods:
Save maintenance costs

Reduce power consumption

Achieve longer service life

Increase system availability

Comply with authorized necessities (e.g: TA-Luft, ATEX)

READ: Full-service capability important for dependable pump provide

Core areas in Retrofitting

The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and past adjustments to the supplies.
Hydraulic modifications

Some of the hydraulic modifications may involve:
Remachining of existing impellers

Installation of latest impellers for off-design situations

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 changes:
Closed bearing brackets enhance the smoothness of operation and prolong the bearing life

Installation of mechanical seal techniques

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

Use of optimised supplies

The following are its a few of the supplies that a variety of the optimised materials that could be used:
Super duplex stainless-steel grades or nickel alloys

Ceramic mineral castings for impellers, put on plates, cover and casing – to be used with finely dispersed, extremely abrasive options

Non-metallic rings and bushes

Ceramic plain bearings

Surface coatings
