GM-ME Series Melt Gear Pump **Model No.:** GM-ME series **Scope of Application:** PS, PP, PET, PVC, PC, PMMA, PA, ABS, PE-LD, etc. **Application:** Transportation, Pressurization, or Metering **Heating Method:** Electric Rod Heating **Outlet Pressure:** ≤40MPa (6000 Psi) **Trademark:** Gmach **Transport Package:** Seaworthy Packaging **Specification:** SGS, CE **Origin:** Zhengzhou **HS Code:** 8421299090 The GM-ME series melt gear pump is specifically designed for thermoplastic extrusion processes, such as sheet, plate, tube, and film industries that require a stable extrusion pressure and flow system. Installed between the extruder and die head, it functions as a metering pump. This series features a unique gear structure and specialized flow design to ensure consistent outlet pressure and flow rate. **Key Features of GM-ME Series Melt Gear Pump:** (1) Minimal melt flow pressure pulsation, enabling linear output, suitable for precise extrusion systems. (2) Capable of operating under high temperature (350°C), high pressure (40MPa), and high viscosity (40,000 Pa·s) extrusion conditions. (3) High precision, durable construction, and long service life. (4) Ensures stable pressure and flow, improving product quality and production efficiency. **Main Functions of the Extrusion Melt Gear Pump:** - Significantly improves the pressure stability of the extrusion die, enhancing product quality. - Enables linear melt flow output, making it easier to control. - Increases extrusion output and production capacity. - Reduces load, saves energy, and lowers costs. **Technical Data:** - Viscosity: 1–40,000 Pa·s (1,000–40,000,000 cP) - Suction Pressure: 0–30 MPa - Discharge Pressure: 0–40 MPa - Differential Pressure: 25 MPa - Temperature: ≤350°C - Heating: Electric **Application Fields:** - Processing: PET, PBT, PA6, PA66, PA12, LDPE, LLDPE, HDPE, HMWPE, PP, EVA, PB, PS, HIPS, ABS, SAN, PC, PES, PMMA, POM, TPU, and other high-viscosity polymers. **Structure of GM-ME Series Melt Gear Pump:** - Rotor Type: Helical Cylindrical Gear - Heating Method: Electric Heating **Optional Accessories:** - Adapters - Support Stands - Upstream Equipment: Screen Changer, Filter Mesh, Vacuum Cleaning Furnace **Packaging & Shipping:** - Inner Packaging: Bubble protection wrap film - Outer Packaging: Wooden case - Shipping: Available by sea or air based on customer requirements **About Gmach:** Zhengzhou Great Machinery Co., Ltd. is a high-tech company with strong technical background and professional team, providing competitive solutions to customers globally.
