Working characteristics of DESMI Rotan asphalt gear pump

Rotan asphalt gear pumps are gear pumps and a type of water pump. Asphalt gear pumps are 

primarily used in low-flow, high-lift water systems, such as drinking water supply systems, pressure

 boiler water supply systems, and high-purity water purification systems.

Asphalt gear pumps generally offer the advantages of high output, low energy consumption, and 

low manufacturing costs. They can be used to insulate, heat, and cool the pumped liquid using media 

such as thermal oil, steam, hot water, and cold water. They are widely used in industries such as chemical 

raw materials, pharmaceutical packaging, food, cosmetics, and pesticides.

Asphalt gear pumps are highly reliable, primarily in terms of service life, operating mode, and frequency. 

Furthermore, asphalt gear pumps are not only used for the extrusion and compounding of polymer 

materials, but their applications have expanded to include feed, electrodes, explosives, building materials, 

packaging, paper pulp, and ceramics. Important considerations during operation include: the asphalt gear

 pump must operate within a power supply voltage fluctuation range of 15%-10% of the rated voltage; 

during installation, ensure that the arrow on the valve body aligns with the flow direction of the medium. 

Do not install in areas subject to direct dripping or splashing water. Asphalt gear pumps should be installed

 vertically and upwards. The pipes should be thoroughly cleaned before installation. The medium entering 

the pump should be free of impurities. A filter should be installed before the valve.

Asphalt gear pumps can be very long and easy to maintain if they are installed and used according to 

specifications and are guaranteed by reputable manufacturers.
