Description
A recent and accurate technical project has made possible the realization of this new series of multicellular pumps with the achievement of the highest hydraulic performances in the category. The MLH series consists of horizontal axis multistage centrifugal pumps equipped with two supports at the ends suitably sized for housing the bearings. The delivery and suction bodies, equipped with support feet, 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 three sides while the transmission shaft, with two possible opposing protrusions, allows clockwise or anticlockwise rotations and couplings in series with several pumps of the same family. The shaft seals, both stuffed and mechanical, they are connected to a compensation system that attenuates the highest operating pressures, preserving from unexpected malfunctions. The impellers, housed in wear rings and dynamically balanced with extreme precision, the ball bearings, amply dimensioned to withstand radial and axial loads in both directions, give characteristics of absolute reliability and durability. The MLV series includes groups of vertical axis multistage monobloc electric pumps. Together with the best axial compensation techniques that do not burden the rotor bearings, the excellent hydraulic characteristics of these pumps once again guarantee full reliability of silent and vibration-free operation. The main uses of these pumps concern: Conveying of water in plants for industrial, aqueduct and civil use; snow-making systems, fire-fighting service, pressure raising, irrigation.
