The high-viscosity pump is a new type of positive displacement pump developed according to the requirements of petroleum, chemical, paint, grease, medicine, dyestuff, and food industries. Because the product can be selected from different materials and its unique structure, it can be widely used in different properties. Different viscosity media delivery. High-viscosity pumps generally require a medium temperature of -10°C to 200°C and a viscosity requirement of 1.0 cst to 300,000 cSt.

The LCX Roots pump is a kind of high viscosity pump. It is based on the LC type pump. In order to solve the problem of transporting the asphalt and condensate, it is added to the outer surface of the pump casing or the end cap and the thermal insulation layer is circulated using steam or heat transfer oil. Insulation of the pump's working chamber provides convenient and good conditions for the continuous and intermittent operation of the pump.

In the pump chamber of the LCX Roots pump, two "8" shaped rotors are mounted perpendicular to each other on a pair of parallel shafts, and a pair of gears having a transmission ratio of 1 are synchronized to rotate in opposite directions to each other. Between the rotors, there is a certain clearance between the rotor and the inner wall of the pump casing, which can realize high-speed operation. Since the LCX Roots pump is a vacuum pump with no internal compression and usually has a very low compression ratio, high and medium vacuum pumps require a foreline pump. The ultimate vacuum of a Roots pump depends on the structure and manufacturing accuracy of the pump itself and on the ultimate vacuum of the foreline pump. In order to increase the ultimate vacuum of the pump, a Roots pump can be used in series.

LCX Roots pump is divided into belt drive and gear reducer drive. Roots pump has many advantages such as low speed, high efficiency, low power consumption, strong self-priming ability, easy to use without oil, etc. It has been widely used in transportation for decades. Petroleum and petroleum products and industrial plants transport various oils and liquids. Beijing Oil Pump Factory has provided oil, paint, lubricants, glass glue, grease, toothpaste and light alkaline liquids to the oil industry and industry for many years. In the food industry, it can transport various liquids such as bean paste, yeast, and sugar syrup. Oil tankers and tankers are fast, efficient, and easy to use. They can work in reverse.
