MU-LDS

Product catalog summary

Overview: The document outlines the technical specifications and features of MU-L and MU-LDS vertical in-line centrifugal pumps, focusing on their design, applications, and key characteristics.

Specifications:

Self-Priming: Certain models feature a self-priming mechanism using a liquid ring or air ejector.
Back Pull-Out Design: Facilitates the removal of rotating components without affecting the pipes, pump casing, or motor.
Base Plate: Constructed with the pump casing for smaller pumps and made of welded steel for larger ones.
Motor Frame: Typically constructed from welded steel, with stainless steel used for non-magnetic versions.
Special Versions: Available in shock-proof, vibration-proof, noise-proof, and non-magnetic versions as per Naval Rules.

Applications:

Suitable for handling fresh and sea water, condensate, oils, chemicals, and petrochemical products.
Primarily used in shipbuilding, heating plants, air conditioning systems, aqueducts, effluent treatment plants, fire fighting, and petrochemical plants.

Main Features:

Pump: Centrifugal type with volute casing, vertical construction, single stage, single flow, and in-line flanges.
Impeller: High efficiency, closed type, and balanced both statically and dynamically.
Mounting System: Shaft supported by radial and thrust ball bearings, either grease or self-lubricated.
Seal: Single mechanical seals conforming to DIN 24960, with options for special or cartridge type seals for specific uses.

MU-LDS Specifics:

Description: Single stage vertical centrifugal pumps with a spacer coupling design, featuring a high efficiency double inlet impeller and balanced axial thrust.
Applications: Ideal for fresh water, sea water, industrial water, and other clean liquids in shipbuilding and land-based industries.
Versions: Available in six sizes with materials such as cast iron, nickel-aluminium bronze, stainless steel, or special alloy.
Main Features: Engineered for optimal performance and minimal maintenance, featuring a back pull-out design for easy maintenance.

Materials and Pressure:

Materials: Options include cast iron, stainless steel, bronze, and special alloy.
Max Working Pressure: 10 bar for cast iron, 16 bar for stainless steel, bronze, and special alloy.

Interchangeability: Components such as casings, impellers, shafts, and mechanical seals are interchangeable across different models.
