DOLPHIN LA

Product catalog summary
Overview: The Dolphin LA series comprises high-quality, single-stage liquid ring vacuum pumps designed for industrial applications. These pumps are suitable for continuous operation and can handle critical tasks such as evacuating saturated gases and vapors. The document provides technical specifications and operational guidelines for models LA 0053 to LA 1111 A, including suction capacity, power requirements, and water usage.
Specifications: The pumps are available in various sizes and material combinations, allowing customization for specific industrial needs. They are ATEX certified for safety in explosive environments, with certifications including Equipment Group II, Category 1(i)/2(o) G, Explosion Group II B, and Temperature Class T4(i)/T4(o). The document outlines nominal displacement, compatibility with specific motor ratings, and operational conditions such as air and water temperatures.
Principle of Operation: The pumps use water as the service liquid. An eccentrically mounted impeller rotates within a partially liquid-filled casing, creating a liquid ring that compresses and discharges gas. The system can operate in once-through, partial recovery, or total recovery modes.
Material Specifications: Constructed from materials like cast iron, stainless steel, aluminum bronze, and titanium, the pumps ensure compatibility with different industrial environments and processes.
Technical Data: Detailed technical specifications for various models include nominal displacement, ultimate pressure, motor power, speed, sound level, and weight, varying across models to suit different applications.
Performance Curves: Performance curves for each model show suction capacity, power consumption, and water requirement at frequencies of 50 and 60 Hz, essential for understanding operational efficiency and water flow.
Dimensional Data: Detailed dimensions for each pump model, including measurements for bearing housings and other critical components, are crucial for installation and maintenance planning.
Accessories: The document describes liquid separators, which conserve operational fluid by separating it from the gas at the pump's outlet. Types include the compact Aufbauabscheider and the efficient AquaMin, which can save up to 90% of operational fluid in an open circuit. Other accessories include anti-cavitation protection, heat exchangers, gas ejectors, non-return valves, drain valves, and vacuum relief valves.
Key Recommendations: It is recommended to select the appropriate material and configuration based on specific application and environmental conditions. Monitoring operational conditions such as gas type, fluid temperature, and pressure is crucial to optimize performance. The use of mechanical seals and other accessories should be tailored to operational requirements.
Applications: The pumps are applicable in industries such as chemical, pharmaceutical, oil and gas, plastics, beverage, environmental technology, paper, medical, food, brick making, drying/impregnation, absorption/degassing, and metallurgy.
