Off-the-Shelf Range of Single Stage Centrifugal Pumps

Centrifugal Pumps to DIN 24255 For Use in The Civil, Agricultural and Industrial Fields

The CM series is made up of single stage electric monobloc pumps with a flanged hydraulics/motor connection. The pump casing is manufactured in accordance with the provisions of DIN 24255-NF E 44 III-UNI 7467 standards, regarding hydraulic dimensions and connection points.

The pumps may be installed in all positions, except where the suction point is directed downwards. The design of these machines allows the rotating parts and the motor to be removed from the pump casing without having to disconnect the pipes. Thus, any maintenance is easily and quickly performed.
