SEIM, after 4 decades of production, have achieved a leading position in the screw pump market worldwide.
Our high volume production of market leading products (more than 1,5 million screw pumps installed) including heat exchangers and relief valves (over 100.000 each) has placed us in a dominant position in many different fields of application (to name but a few:

· Power Generation
· Petrochemical
· Oil and Gas
· Wind power generation
· Paper and Steel industry
· Automotive
· Marine
· Machine Tools
· Hydraulic

Our wide range of Products grant capability to satisfy demand in all fields of application, also thanks to the continuous extension of our Manufacturing Program. SEIM Products are fully developed in our Company, thanks to know-how achieved during more than thirty-six years experience in manufacturing screw pumps. R&D Department follow criteria like "answer to demands by the market", developing new Products to satisfy world-wide Customer's requests. Customized Manufacturing is part of our winning experience, thanks to high tech apparatus at its own disposal and synergic collaboration both with customers and distributors, implementing performances for existing Products introducing latest news in terms of materials, machining process, analysis and control systems (both during parts manufacturing and on "ready to delivery" products). All Products manufactured by SEIM are 100% tested and data concerning pumps are stored in our files.
Thanks to Products identification achievable by model code and serial number is possible:

· find out product performance, also "after sale"
· to issue certificates for pump performances (both SEIM standard test conditions or customer's requested conditions).

SEIM Quality System, recognized since November 1995 by ISO 9000 certification (according to ISO 9001 and extended to UNI EN ISO 9001:2000 in October 2003), rules all activities in the Company, with the aim to fully satisfy customer's expectation in terms of Products Quality, reliability in delivery and stock availability for finished Products.
SEIM Sales Network is extended throughout all Continents, both directly by local SEIM offices and through collaboration with local Representatives and it is in continuous development: it is capable to grant qualified technical support in selecting our Products, ready to deliver Products and to handle directly a wide portfolio of international leading Customers.
