The main flowing parts 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 transported liquid and the pump. When transporting liquids with high viscosity, a reducer, variable-speed motor, or belt pulley should be used for transmission to reduce the pump's speed.

The CLB asphalt pump is a positive displacement pump, primarily 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 a simple structure, compact size, smooth and reliable operation, low pressure pulsation, stable flow rate, low noise, and is ideal for transporting high-temperature viscous liquids, thin or thick suspensions, emulsions, with a medium viscosity range of 0.02 - 15 PaS and temperatures up to ≤300°C. It is applied in various industries such as petrochemicals, textiles, metallurgy, machinery, electricity, machine tools, ships, glass, and highways. The asphalt pump is suitable for transporting fuel oil, lubricating oil, hydraulic oil, crude oil, asphalt, and other similar oils and lubricating fluids. It features involute straight gears, and the pump body is equipped with an insulating jacket that can be heated using steam or thermal oil circulation, allowing the pump to operate normally in temperatures below freezing. It is an ideal product for asphalt transportation in road construction and other industries.
