SERIES MLV Multistage

Presentation and construction features:
The MLV series includes groups of monoblock, multistage, vertical axis electropumps. Together with the best axial compensation techniques that do not weigh on the rotor bearings, the excellent hydraulic characteristics of these pumps once again guarantee full, vibration-free, silent-running reliability.
The delivery and suction bodies allow the hydraulic pack to be clamped by means of four sturdy tie rods with high compactness and rigidity. The ports can be oriented on four sides while the shaft seal, both with packing and mechanical, is connected to a compensation system that attenuates the highest operating pressures, thus protecting against unexpected malfunctions. The impellers, housed in wear rings and dynamically balanced with extreme precision, and the ball bearings, amply dimensioned for the support of radial and axial loads in both directions, confer characteristics of absolute reliability and durability.
The principal uses for these pumps involve: Conveying water through industrial, municipal water and home systems; snowmaking systems, fire-protection systems, raising pressure and irrigation.
