Melt Pumps for Precision Extrusion of Thermoplastics

The ZB-B melt pump provided by Batte is specially used for the precision extrusion of thermoplastics, such as precision extrusion systems that require particularly stable pressure and flow in the sheet, plate, pipe, film and other industries. It is installed at the outlet of the extruder and the die head. It is used as a metering pump in between. This series of melt pumps adopts special gear structure and optimized flow channel design to ensure no pulsation of pressure and flow at the outlet. The melt gear pump for thermoplastic materials is mainly used for conveying, pressurizing and metering of medium and high viscosity polymer melts. It is suitable for almost all thermoplastic materials: PS, PP, PET, PVC, PC, PMMA, PA, ABS, EVA , ABS, HDPE, LDPE, PE-LLD, etc.

The working principle of the hot plastic melt gear pump: the plastic extrusion melt pump gear pump is composed of the tooth profile of two gears, the pump body, and the side cover plate to form the pump's feeding and feeding area, and the discharging area. At the same time, the melt is transported by the change of the working volume caused by the mutual engagement of the main and slave gears. When the gear rotates in the specified direction, the melt will enter the middle of the tooth grooves of the two gears in the feeding area, and then the gears will start to rotate, and the melt will be brought into the belt feeding area from both sides, and the gears will mesh again, allowing The melt in the gullet is extruded out of the discharge area and forced to the outlet pipe. As long as the pump shaft rotates, the gear transfers the melt to the outlet, so the pump outlet can reach a very high pressure, but the inlet flow and pressure are not too high.

Main features of thermoplastic precision extruder melt pump: extremely small pressure flow pulsation, can achieve linear output of flow, suitable for precision extrusion system; can be applied to high temperature (350℃) high pressure (40MPa) high viscosity (40,000Pas) ) working conditions; it has precise structure, high precision and long service life.

Thermoplastic material is composed of melt gear pump structure: The melt pump structure is composed of pump casing, driving gear, driven gear, sliding bearing, front and rear plates, packing seal, etc. Melt gear pump drive system includes: motor, reducer, universal coupling, pump connector, reducer connector, etc., which can be configured according to user needs. info@battemachinery.com
