Summary:
1. The LQRY Hot Oil Boiler Thermal Oil Pump is suitable for heat-conducting oil or other hot oils with a temperature of ≤370°C.
2. It features a reasonable structure, advanced technology, high efficiency, and long-term stable operation without leakage in the hot state. It is used to transport non-corrosive high-temperature liquids without solid particles, using direct air cooling.
3. This pump is widely used in industries such as petroleum, chemical, rubber, leather, food, grease, boilers, construction, road maintenance, pharmaceuticals, plastics, synthetic fibers, textile, printing, and dyeing.
Seal Type:
1. Combines packing seal and mechanical seal. Packing uses high-temperature resistant filler material, offering good thermal adaptability.
2. Mechanical seal uses carbide materials with high mechanical strength and wear resistance, ensuring sealing performance under high temperatures.
3. PTFE lip seals offer 25 times better reliability than rubber seals and are highly corrosion-resistant.
