Pump retrofitting: New Lease of Life for Old Pumps

For all the dedication of a mine’s service team to the beneficial greatest follow in pump administration, sometime, encountering cases of pump element wear and tear is inevitable – a matter of when and not if. And when it does happen, part wear inhibits pump efficiency. ขนาดpressuregauge is at that time where, timeously, mines might have to noticeably think about retrofitting as a feasible option.
A rational business choice

In this setting, where costs of capital gear costs are growing, alternative could additionally be a smart business determination. In an advisory focused at mines and other industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise decision: “Retrofitting is a superb alternative to buying a new product and can be carried out on pumps no matter their intended use. It is equally appropriate for industrial, water supply and waste water disposal functions in addition to for the facility supply business.”

It is simply natural for mine operators to ponder buying new pumps. New pump fashions meet contemporary necessities like improved energy effectivity, compliance with new authorized necessities (relating to emissions and safety), prolonged service life and know-how which produces working information. But this will not necessitate replacing an outdated pump mannequin, KSB Pumps says, as retrofitting might give an old pump a brand new lease of life, specifically in the following methods:
Save maintenance prices

Reduce energy consumption

Achieve longer service life

Increase system availability

Comply with authorized 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 supplies, above and beyond changes to the supplies.
Hydraulic modifications

Some of the hydraulic modifications could contain:
Remachining of present impellers

Installation of recent impellers for off-design situations

Optimisation of volute casing for off-design conditions

Adjustment of the variety of stages (on multistage pumps)

Mechanical changes

The following are a variety of the mechanical adjustments:
Closed bearing brackets improve the smoothness of operation and extend the bearing life

Installation of mechanical seal techniques

Employment of cellular surface wear rings to improve effectivity, rotor dynamics and dry running properties

Use of optimised supplies

The following are its some of the materials that a variety of the optimised materials that might be used:
Super duplex stainless steel grades or nickel alloys

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

Non-metallic rings and bushes

Ceramic plain bearings

Surface coatings
