MU-L

Product catalog summary

Overview: This document outlines the technical specifications and features of the MU-L and MU-LDS models of vertical in-line centrifugal pumps. These pumps are suitable for various industries such as shipbuilding, heating, air conditioning, and petrochemical sectors.

Specifications:

Construction: The pumps are centrifugal with a volute casing, vertical construction, single stage, and single flow with in-line flanges. They feature a high-efficiency, closed-type impeller that is balanced for axial thrust.
Materials: Options include cast iron, stainless steel, bronze, and special alloys. The maximum working pressure is 10 bar for cast iron and 16 bar for other materials.
Mechanical Seal: Equipped with single mechanical seals conforming to DIN 24960, with options for special seals or cartridge types for specific applications.
Mounting System: The shaft is supported by radial and thrust ball bearings, with options for grease or self-lubrication.

Features:

Back Pull-Out Design: This feature allows maintenance of internal parts without removing the motor and pipes.
Self-Priming: Some models include a self-priming element with a liquid ring or air ejector.
Special Versions: Available according to Naval Rules, including shock-proof, vibration-proof, noise-proof, and non-magnetic versions.

Applications: These pumps are suitable for handling fresh and sea water, condensate, oils, and chemical products. They are primarily used in shipbuilding, heating plants, air conditioning systems, aqueducts, effluent treatment plants, and fire fighting.

MU-LDS Specifics:

Design: Features a single stage with spacer coupling design, double inlet impeller, low NPSH requirement, and balanced axial thrust.
Versions: Available in six sizes with automatic priming systems and special executions for naval applications.

Maintenance: The design allows for easy replacement of bearings and seals without complete pump dismantling. The motor stool is designed to reduce vibrations and facilitate maintenance.
