PA Wastewater Screw Pump
Brand: WAMin 1978 WAMGROUP 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 the factory topping their triple pitch 3.2 metre diameter, 21 metre long, and more than 20 ton weighing monster powered by a 370 kW drive supplied in 1984 to a municipal waste water treatment plant in Rome.
In recent years the demand for Water Screw Pumps has increased again after a temporary slump in the 1990s. In spring 2014, RONCUZZI set a new record producing three Archimedean screws having a diameter of 4 metres each.
The PA Archimedean Screw Pump is a special type of volumetric pump, able to satisfy users requirements as regards favourable investment and running costs, flexibility and reliability.
