Comparison of Screw Pump Bag Feeding Packaging Machines

Comparison with Other Packaging Machines Comparison with Screw - pump Bag - feeding Packaging Machines In terms of conveying accuracy: The servo - rotor - pump has higher accuracy. When the screw - pump is conveying some materials with high viscosity and large particles, the metering accuracy may be affected due to the gap between the screw and the pump casing and the blockage of particles. However, the rotor structure and closed - chamber design of the servo - rotor - pump make it more tolerant to particles and the metering accuracy is more stable. In terms of the viscosity of applicable materials: Both are suitable for high - viscosity materials, but the servo - rotor - pump has a stronger adaptability to materials with greater viscosity changes. The conveying efficiency of the screw - pump will decrease as the viscosity of the material increases, while the servo - rotor - pump can maintain relatively stable conveying performance within a certain range.
