High Temperature Stainless Steel Gear Metering Pump

The high-temperature stainless steel gear metering pump is a positive displacement pump featuring a pump body made of 304/316L stainless steel, making it suitable for high-temperature operating conditions.

It conveys media through volume changes generated by gear meshing, delivering a flow rate that varies linearly with rotational speed and ensuring high metering precision and stability even at high temperatures.

Capable of handling media such as high-temperature resins, hot-melt adhesives, asphalt, high-temperature oils, and heated chemical raw materials, it is widely used in high-temperature processing applications across industries including chemicals, advanced materials, asphalt, coating, chemical fibers, and molecular distillation.

Features
1. Positive Displacement Principle: Flow rate is determined by the volume of the gear tooth spaces; output is minimally affected by pressure fluctuations, ensuring high metering repeatability. Flow can be adjusted by varying rotational speed, making it suitable for automated proportioning systems.
2. High-Temperature Resistant Stainless Steel Construction: Wetted parts are made of 304/316L stainless steel, ensuring structural stability and resistance to thermal deformation at high temperatures. An optional thermal insulation jacket is available for transporting media that require temperature maintenance.
3. Specialized High-Temperature Sealing: Equipped with high-temperature resistant seals (e.g., PTFE, graphite); options include double mechanical seals and leak-free magnetic drive configurations to effectively prevent leakage of high-temperature media.
4. Suitable for Medium-to-High Viscosity Media: Ideal for high-viscosity fluids such as high-temperature resins, asphalt, hot-melt adhesives, and hot oils; ensures pulse-free transport and steady discharge.
5. Compact Structure and Easy Maintenance: Modular design allows for convenient disassembly and servicing; compatible with servo or variable-frequency drive (VFD) motors and supports 4–20mA and RS485 communication for integration with PLC-controlled automated production lines.

Application Industries
1. New Chemical Materials: Metered transfer of high-temperature resins and polymer materials
2. Asphalt & Building Materials: Metered transfer of hot asphalt and modified asphalt
3. Coating & Lamination: Metered feeding of high-temperature hot-melt adhesives and coatings
4. Chemical Fiber Spinning: High-temperature metering of spinning finish oils
5. Petroleum Additives: Proportioning and transfer of heated oil products and additives
