Single – Stage Centrifugal pumps


These pumps have a vast range of uses both in agricultural and industrial fields. They can be used for irrigation systems, for water supply systems and, in industry, to pump any kind of liquid under pressure. They are particulary suitable for coupling with fast Diesel engines and 2 pole electric motors.


The hydraulic part is centrifugal, with horizontal axis and a single impeller. The in-lets are flanged in accordance with UNI PN10 standards the in-take is placed axially while the pressurizing one is radial and can be turned. The closed radial impeller is dynamically and hydraulically balanced. Packing seal with adjustable flange and the shaft at the seal is protected by a hard chromium facing. The rotating and hydraulic section rest on a sufficiently large support unit. The pump shaft is supported by two large bearings set far apart to guarantee correct distribution of the axial and radial thrust. The bearings are oil lubricated and there is a dip-stick to check the oil level.
