According to the characteristics of the asphalt conveying industry, the production of products such as thermal insulation gear pumps, high viscosity internal gear pumps, screw pumps, etc., each series of products have gone through technological upgrades, process updates, technicians with hard work and wisdom to solve a variety of difficult problems in the field of asphalt conveying. Asphalt transfer pumps convey medium with viscosity up to 1,000,000 cst, temperatures up to 420°C, and flow rates from 0.1m³/h to 1,000m³/h.
