Application and working condition of melt pump

Application of melt pump

Melt pump is mainly used for high temperature and high viscosity polymer melt conveying, supercharging and metering. Abroad, it is widely used in plastics, resin, rubber, chemical fiber products extrusion molding. Such as: granulation, film, pipe, sheet, sheet, man-made fiber, optical fiber, medical plastic pipe and other industries. With the development of machinery industry, melt pump is gradually adopted and applied in the domestic market.

Melt pump working condition

1. Working temperature: <400, cleaning temperature: <450, outlet pressure <40 MPa (6,000 psi) viscosity: <4,000,000 cp) 2. Working temperature: 510 (950) cleaning temperature: <590, outlet pressure < 70 MPa (10,000 psi) maximum pressure difference: 50 MPa (7,000 psi) viscosity: <2000 Pa. 00,000cp) 3. Seals are generally spiral and packing seals, but also according to customer requirements using other mechanical seals. 4. Drive motor + reducer + universal coupling + pump body, motor adopts frequency conversion speed regulation, can be adjusted to the required flow at will, also can be used in the form of DC speed regulation and servo drive. 5. melt pump can be controlled accurately by electric heating or heat medium heating.
