The main flowing sections of the CLB asphalt pump are equipped with hollow sandwich layers, which can be insulated and heated using steam, hot water, or heat-conducting oil to maintain the temperature of the liquid being pumped and the pump itself. When transporting liquids with high viscosity, a reducer, variable-speed motor, or belt pulley should be used for transmission to decrease the pump's rotational speed.

The CLB asphalt pump is a容积式泵，mainly used for transporting and spraying high-temperature asphalt liquids. It is suitable for asphalt spraying operations in road and square construction projects. Its significant advantages include simple structure, compact size, smooth and reliable operation, low pressure pulsation, stable flow, low noise, and is applicable for transporting high-temperature thick liquids, dilute or thick suspensions, emulsions, with a medium viscosity range of 0.02 - 15 PaS, and temperatures up to ≤300°C. It is used in various industries such as oil, chemical fibers, metallurgy, machinery, electricity, machine tools, ships, glass, highways, and more. The asphalt pump is suitable for transporting fuel oil, lubricating oil, hydraulic oil, asphalt, and other similar lubricants and lubricating fluids. The gears have involute straight gears, and the pump housing is equipped with an insulating jacket that can utilize steam or heat transfer oil circulation for insulation. Therefore, the pump can operate normally in temperatures below zero, making it an ideal product for transporting asphalt in road construction and similar industries.
