MU-L/LDS

Product catalog summary
Overview: This document outlines the technical specifications and features of the MU-L and MU-LDS vertical in-line centrifugal pumps, which are suitable for applications in shipbuilding, heating, air conditioning, and the petrochemical industry.
Specifications:
  • Self-Priming: Some models feature a self-priming element using a liquid ring or air ejector.
  • Back Pull-Out Design: Facilitates the removal of rotating components without affecting pipes, pump casing, or motor.
  • Base Plate: Small to medium pumps have a cast base plate with the pump casing, while larger pumps use a welded steel base plate.
  • Motor Frame: Typically constructed from welded steel, with stainless steel options for non-magnetic applications.
  • Special Versions: Available in shock-proof, vibration-proof, noise-proof, and non-magnetic versions as per Naval Rules.
Main Features:
  • Pump Type: Centrifugal with volute casing, vertical construction, single stage, single flow, in-line flanges.
  • Impeller: High efficiency, closed type, axially balanced with an annular chamber and balancing holes.
  • Mounting System: Shaft supported by radial and thrust ball bearings, available in grease or self-lubricated versions.
  • Seal: Single mechanical seals to DIN 24960, with options for special seals or cartridge types for specific applications.
MU-LDS Specific Features:
  • Design: Single stage with spacer coupling, double inlet impeller, low NPSH, and balanced axial thrust.
  • Applications: Suitable for fresh water, sea water, industrial water, and other clean liquids in both shipbuilding and land-based industries.
  • Versions: Available in six sizes with materials like cast iron, nickel-aluminium bronze, stainless steel, or special alloys.
  • Maintenance: Back pull-out design allows easy maintenance without removing motor and pipes.
Materials and Pressure:
  • Materials: Cast iron, stainless steel, bronze, and special alloys.
  • Max Working Pressure: 10 bar for cast iron, 16 bar for stainless steel, bronze, and special alloys.
Interchangeability: Components such as casings, impellers, shafts, and mechanical seals are interchangeable across models.
