When the asphalt gear pump was used in winter, the customer was very negligent. Asphalt gear pumps without the function of heat-insulated jackets were often used, so that the cold medium was frozen, the pump body was not rotating smoothly, and it could not work normally.

Asphalt insulation gear pump is divided into ordinary and cast steel materials, both with insulation jacket, heat pump for condensation at room temperature or crystallized by heating and maintain a certain temperature and easy to flow and lubricating liquid As well as the need for insulation in outdoor installations and processes in high-cold areas, the first warm-up of the pump reduces the starting power of the pump. The pump body of the asphalt gear pump is provided with a hollow sandwich and is provided with an inlet and an outlet flange, which can be used to heat, insulate and cool the conveyed liquid and the pump by the medium such as heat transfer oil, steam, and hot water.

Suitable for conveying corrosive or non-corrosive liquids with high hygienic requirements. The conveying medium does not contain solid particles, the temperature is not higher than 350°C, the viscosity is 5 cSt-1500 cSt, such as various chemical raw materials, filling Pharmaceuticals, food, cosmetics, pesticides, detergents, printing and dyeing, brewing, resins, plastics and other industries.
