Dolphin LMs are single-stage vacuum pumps for rough vacuum applications from atmospheric pressure to 130 hPa (mbar) ultimate pressure. Dolphin LTs are two-stage vacuum pumps and operate from atmospheric pressure to 33 hPa (mbar). The Dolphin LM/LT series is available in a total of 13 sizes, allowing an exact match to every process. Vacuum drying is employed when delicate materials need to be dried rapidly and without damage. It is used in food processing to avoid loss of quality or taste. It is also highly suitable for materials with large surface areas, such as the removal of water from plastic granules or drying complex machine parts after cleaning. The high tolerance of Dolphin LM/LT vacuum pumps to water and moisture make them the ideal choice for drying processes.
