Meccanotecnica Umbra is a leading manufacturer of mechanical seals for civil installations.
This category of mechanical seals includes all seals designed for water circulation pumps in heating systems and for pumps in autoclaves for drinking water. Also of particular interest is the civil application of mechanical seals for swimming pool and whirlpool pumps, as well as for all common garden pumps.
Mechanical seals can be extensively customised to create truly tailor-made solutions for specific customer requirements. Minimum order quantities can also be supplied through our extensive distribution network.
All our sealing systems ensure maximum insulation thanks to a specific design for these types of applications. One of the most important characteristics for seals for civil installations must in fact be the ability of the sealing faces to not stick together after prolonged pump stops, such as summer shut-downs of heating systems.
Great care has also been taken in the selection of materials used to make mechanical seals for civil applications. Our sealing systems are generally characterised by the pairing of strong sealing ring materials such as graphite and alumina, which can guarantee a long sealing life as well as give the pump quiet operation and excellent starting torque.
