Roots pumps are primarily classified into two types: belt-driven and gear-reduced pumps. The characteristics of these pumps include low rotational speed, high pumping speed, large flow rate, low power consumption, strong self-priming capability, and no need for oil lubrication. They can operate in both forward and reverse directions, making them convenient to use. They are widely used in the transportation of oils in industries such as petroleum and factories, including lubricating oils, coatings, high-viscosity adhesives, greases, and other liquids. Roots pumps can also be used for food transportation, such as soy milk, yeast, honey, and more. Additionally, Roots pumps can be equipped with insulation jackets for steam, hot water, or thermal oil insulation. They are extensively used in various industries, including petroleum, chemical, pharmaceutical, food, textile, daily chemical, and defense, for liquid transportation. Roots pumps are suitable for transporting high-viscosity liquids due to their unique advantages. Here are the four main advantages of Roots pumps:

1.Reasonable and compact structure with fewer but precise components, allowing for easy operation and maintenance, and high working efficiency.

2.They operate at low speeds compared to the rotors, resulting in smooth operation, low noise, minimal wear, and long service life.

3.The suction side of the pump has a large intake area, a slow pulsation volume due to the gear design, low pulsation pressure, strong suction capacity, and can achieve a high vacuum level of up to 5m.

4.The rotational speed of the Roots pump is directly proportional to the flow rate, providing the function of actively adjusting the flow rate.
