Archimedes screw pump WAM S p A

I 1978 SPECO® started manufacturing PA-type Archimedean Water Screw Pumps. By the mid 1980s the Company had gained a leading position among European manufacturers due to the acquired know-how and expertise in production technology. Only logistic problems could stop SPECO® topping their triple pitch 3.5 metre diameter, 23 metre long, and more than 30 ton weighing monster powered by a 500 kW drive supplied in 1993 to a municipal wastewater treatment plant in Rome.
The 1990s brought major changes to the wastewater industry. The dramatically decreasing demand for large Archimedean Water Screw Pumps in the industrialised countries made SPECO® now focus on similar technologies, such as screening and compacting. However, in recent years the demand for Water Screw Pumps, which are now supplied by WAMGROUP associates RONCUZZI®, has increased again.
