NTT Series German Thermal Oil Pump Heat Transfer Circulation Pump

Germany Allweiler-NTT Thermal Oil Pump, Heat Transfer Fluid Circulation Pump, NTT Hot Oil Pump

Hot oil pumps are widely used in China's carrier heating systems and have entered various industrial fields such as petroleum, chemical, rubber, plastic, pharmaceutical, textile, printing and dyeing, road construction, and food. They are mainly used to transport high-temperature, weakly corrosive liquids without solid particles, with an operating temperature of ≤350°C, making them an ideal heat transfer oil circulation pump. They can be used in the petroleum and chemical industry, textile printing and dyeing industry, food industry, chemical industry, plastic industry, and for heat transfer fluid transportation.
