Raw water collection
The Michelin tyre manufacturing plant in Hallstadt pumps cooling process water as raw water from the Main River less than two kilometres away. The plant was opened in 1971 and has been continually modernised since, even with regards to how their water processing is managed. The cooling water needed to reduce tyre temperature after vulcanisation is stored in tanks under the ground floor.

Caprari specialises in challenging installations. In the end, Michelin did not opt for a conventional configuration with a surface free-standing tank and dry-installed pump, but something quite different: in Caprari’s vertically mounted solution the hydraulic system is in water and the motor with lineshaft is placed outside. This has many advantages. For instance, not only is less space required in the factory itself, but maintenance has also been made easier and the drive unit is replaceable in most cases. Thanks to Caprari’s concept it is possible to use several standard motors, also produced by other manufacturers (and even diesel driving systems). As a result, Michelin remains flexible, should new plant extensions be necessary. The P-series conveys up to 400 litres of water per second and reaches delivery heads up to 250 metres – more than enough for a number of industrial uses.
