Libellula Pumps

Product catalog summary
Company Overview
The company, founded in 1942 by Cipriano Caffini, initially focused on agricultural machinery sales. In 1968, it shifted towards manufacturing diaphragm pumps, capturing a significant international market share, with 80% of its products distributed outside Italy. By 1995, the company expanded to produce self-priming centrifugal pumps, known for their easy maintenance and cleaning.
Product Features
The self-priming diaphragm pumps can run dry indefinitely and self-prime rapidly up to 7 meters. They are designed without seals or rotating parts in contact with the liquid, making them suitable for abrasive or acidic fluids. The pumps allow for the passage of solid bodies and require minimal maintenance.
Working Principle
The pumps operate as reciprocating positive displacement pumps. The diaphragm, moved by a crank, creates a vacuum to draw in liquid during the suction phase and expels it during the discharge phase. Proper diameter and free discharge of the pressure line are crucial to prevent damage.
Main Applications
  • Emergency Relief: Ideal for removing mud and water in disaster scenarios due to their reliability and ability to handle large debris.
  • Construction and Civil Engineering: Used to keep excavations dry, even with mud and suspended solids.
  • Marble and Ceramics Industry: Designed to withstand the abrasiveness of marble dust.
  • Water Treatment: Effective in handling solids and abrasive substances in purification processes.
  • Food Industry: Suitable for pumping tomato pulp, fruit juices, and syrups with solids.
  • Animal Breeding: Used for suction of blood and offal in poultry processing.
Performance Limitations
For industrial applications, the total manometric head should not exceed 10 meters to avoid damage.
Overview
The document provides detailed technical specifications and applications for Caffini Libellula diaphragm pumps, widely used across various industries including zootechnics, mechanical, chemical, naval, aeronautical, textile, and paper industries.
Specifications
The pumps are designed to handle a variety of substances, including blood, slaughterhouse waste, fruit juices, tomato waste, acidic or basic liquids, and more. They are available in different models with varying capacities and materials, such as die-casted aluminum, polypropylene, and stainless steel.
Applications
  • Zootechnics and Livestock: Used for pumping blood and waste from slaughterhouses.
  • Mechanical and Chemical Industry: Suitable for handling aggressive substances with safety and reliability ensured by a wide choice of metal and elastomer parts.
  • Naval and Aeronautical: Utilized as bilge pumps and for tank emptying, appreciated for their reliability and resistance to debris.
  • Textile Industry: Effective in pumping wastewater containing fibers without damage.
  • Paper Industry: Capable of handling pasty and thick liquids, with the ability to run dry indefinitely.
Key Features
  • High reliability and resistance to various types of waste and debris.
  • Wide range of materials for diaphragms and valves, including Neoprene®, Dutral®, Hypalon®, and Viton®.
  • Available in different configurations and sizes to suit specific industrial needs.
Technical Data
The document includes detailed tables with specifications such as maximum solids handling, power requirements, and dimensions for various models like LIBELLULA 1-3”, LIBELLULA 1-2”, and SUPERMICROLIB 2”.
Production and Versions
The pumps are available in both standard and industrial versions, with options for self-lubricated components and various construction materials to enhance durability and performance.
