DOLPHIN LB

Product catalog summary
Overview: The Dolphin LB series features high-quality, double-stage liquid ring vacuum pumps designed for industrial use, capable of continuous operation and handling critical applications like evacuating saturated gases and vapors.
Specifications: Available in materials such as stainless steel, cast iron, and titanium, these pumps are ATEX certified, meeting Directive 94/9/EC standards, with equipment group II, category 1(i)/2(o) G, explosion group II B, and temperature class T4(i)/T4(o).
Principle of Operation: Utilizing a liquid medium, typically water, an eccentrically mounted impeller creates a liquid ring that compresses gas. Configurations include once-through, partial recovery, and total recovery systems.
Operating Modes:
  • Once-through system: Continuous feed and discharge of service liquid with gas.
  • Partial recovery system: Liquid is separated, recirculated with fresh liquid.
  • Total recovery system: Liquid is separated, cooled, and reused.
Technical Data: Detailed specifications for models like the Dolphin LB 0063 A, with nominal displacement of 60 m3/h at 50 Hz and 65 m3/h at 60 Hz, and ultimate pressure of 33 hPa (mbar).
Material Specifications: Customizable materials include cast iron, stainless steel, and aluminum bronze, with various mechanical seals for compatibility with different applications.
Technical Specifications: Key parameters include nominal displacement, ultimate pressure, motor rating, pump shaft speed, sound level, and weight for models like LB 3809 A, LB 0710 A, LB 4409 A, and LB 1011 A.
Performance Curves: Provided for air at 20°C with a tolerance of ±10%, using water at 15°C, illustrating suction capacity, power requirements, and water consumption.
Dimensions: Detailed dimensions for various models, essential for installation and integration into systems.
Key Data Extraction: Alignment of nominal displacement and motor rating for optimal performance, sound levels measured per DIN EN ISO 2151, and comprehensive water requirement overview.
Recommendations: Maintain specified operating conditions for temperature and water quality, conduct regular maintenance, and monitor sound levels and water flow to prevent issues.
Procedures: Installation and operation instructions for liquid separators to reduce liquid consumption in open or closed circuits.
Standards and Recommendations: Use anti-cavitation devices like vacuum relief valves and AquaMin separators, and consider heat exchangers and gas ejectors for enhanced performance.
Accessories: Includes non-return valves, drain valves, and vacuum relief valves for optimal operation and prevention of overfilling.
Applications: Suitable for industries such as chemical, pharmaceutical, oil and gas, plastics, and food technology, and processes like drying, impregnation, absorption, and degassing.
Configurations and Options: Customizable configurations and material options for specific applications, highlighting adaptability to various operational needs.
Key Data from Tables: Detailed dimensions for different pump models, crucial for selecting the appropriate model for specific applications.
