We meet the diverse needs of those operating in this field by offering mechanical outfits suitable for all types of industrial applications.

AGRICOLTURE AND CIVIL

AGRICOLTURE AND CIVIL

AGRICOLTURE 

Mechanical seals for agricultural pumps are produced using sealing rings made of hard materials such as silicon carbide or tungsten carbide, which provide maximum resistance to abrasion. Mechanical seals for agricultural applications, especially for OE customers, can be customised to create truly tailor-made solutions for specific customer requirements.

 

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.

INDUSTRIAL INSTALLATIONS 

Mechanical sealing systems are designed instead guaranteed to provide maximum performance and reduce fluid leakage thanks to a specific design for each type of application. Our sealing systems are mostly characterised by a combination of materials such as silicon carbide, tungsten carbide, ceramic, Viton elastomers, Kalrez and FEP, which can insure instead guarantee long service life and excellent reliability of use.

 

FOOD AND BEVERAGE 

The mechanical seals for the food industry supplied by our subsidiary Huhnseal are always customised according to customer specifications - each project is unique, new and tailor-made for the end customer. Mechanical seals for the food industry are designed to prevent the formation of deposits that could cause pollution of the treated product.

PULP AND PAPER 

The products manufactured by our subsidiary Huhnseal are always customised to customer specifications in order to provide the best solutions for each specific case. The work process may in fact involve the use of particularly abrasive fluids that greatly compromise the durability of mechanical seals. To meet this type of requirement and increasingly improve the quality standard of the mechanical seals produced, the company can supply special mechanical seals made of diamond coated silicon carbide.

 

CHEMICAL INDUSTRY 

Meccanotecnica Umbra meets all the production standards of the chemical sector in full compliance with current regulations prepared for the critical needs of the industry. Most mechanical seals for the chemical industry are designed to operate with aggressive, hazardous and polluting liquids, but also with the extreme temperature conditions that these liquids can reach during processing.

PHARMACEUTICAL INDUSTRY 

Mechanical seals for the pharmaceutical industry have a hygienic, safe design. They are specially designed to prevent the formation of deposits that could cause pollution of the treated product (medicine). The materials used for mechanical seal production for the pharmaceutical sector, in particular sealing rings and rubber parts, are all Food-Grade and can be certified FDA, 3-A, USP Class VI, EG 1935 grades.

 

MINING AND SLURRY INDUSTRY 

Sealing systems (rings) specially designed for the mining sector are made from noble materials such as silicon carbide enhanced with diamond coating. In this way, the mechanical seals produced can ensure maximum resistance to wear even under extreme conditions of use,thus increasing their productive life, improving the safety of continuity in the production phase and guaranteeing perfect pump functionality.

Mechanical seals can be extensively customised to create tailor-made solutions to the specific needs of customers and companies in the solar thermodynamic industry. 

For sectors such as Hydroelectric and Municipal/Industrial, Meccanotecnica Umbra is supported by its Canadian subsidiary Fugesco, which designs and manufactures unique, state-of-the-art mechanical sealing solutions up to a shaft size of 4 metres diameter. All products are designed and manufactured by specialised teams with the experience and ability to innovate in order to meet specific customer requirements. The specific mechanical seals for this sector must be able to withstand corrosive fluids, very high temperatures and pressures. Reliable and highly resistant technology is therefore needed.
