Gemex™ Belt Tensioning System

The Gemex™ belt tensioning system allows for the quick and easy replacement of belts on any critical machine without the need of the alignment.

Overview

Our Gemex™ belt tensioning system makes it possible to change belts on any critical machine in just a few minutes. No alignment needs to be done when changing belts or adjusting belt tension - it is done during the initial installation.

Correct alignment and belt tension gives your belts, pulleys and bearings longer and more consistent life, while also providing the conditions for maximum efficiency.

Gemex™ belt tensioning systems are available in standard models for belt drives from 1 kW up to 500kW. We can also offer bespoke designs for machines where our standard models cannot be applied.

These belt tensioning systems can be found in nearly every industrial environment which uses belt transmissions; as well as in clean environments such as the pharmaceutical industry, ventilation systems in hospitals and in other public buildings.

Features and Benefits

High Performance

Gemex™ belt tensioning systems offer consistent high performance in your belt transmission. Running your belt transmission with best possible efficiency will save energy and/or increase machine output.

Minimal Belt Alignment Required

The Gemex™ belt tensioning system makes it possible to change belts in just a few minutes. No alignment needs to be done when changing belts or adjusting belt tension as it is done during the initial installation. Correct belt tension can be achieved without any physical contact with the belts.

Reduced Downtime

Fast belt service means shorter production stops. Correct belt tension and alignment will extend the wear life of belts and pulleys, so the machine will not need to be stopped for maintenance as frequently.

Long Wear Life

Achieving the maximum wear life of all components results in reduced consumption of spare parts.

Enhanced Safety in Belt Maintenance

Fast and easy operation means less stress on the maintenance staff. No heavy operations and less time spent in the line of fire.

Why Weir?

Benefiting from more than 20 years’ experience in belt transmission design and manufacture, Gemex® belt tensioning systems have become the standard in many process industries worldwide, and are ideally suited to the Warman® slurry pump range.

The Gemex® unit has been specifically designed to integrate with our range of Warman® centrifugal pumps. Its design makes using and maintaining Warman® pumps even more efficient and less time consuming.

Applications

Gemex™ belt tensioning systems can be used in a variety of applications within mining, food, chemical, manufacturing and other general industries.

Gemex™ belt tensioning systems can be used in underground and open pit mines, gravel pits, rock crushers and mineral processing as well as for coffee processing, within breweries, sugar refineries and flour-mills.

Some of our Gemex® units have also been specifically designed to integrate with our range of Warman® pumps.
