Sunkaier Genipump - Melt Gear Pump

The concept of a gear pump is very simple. Its most basic form is that two gears of the same size mesh and rotate with each other in a close-fitting shell. The inside of the shell is similar to the “8” shape, and two gears are installed inside. The outer diameter and both sides of the gear are closely matched with the housing. The material from the extruder enters the middle of the two gears at the suction port, and fills the space, moves along the housing with the rotation of the teeth, and is finally discharged when the two teeth mesh.

Polymer processes require pumps that gently process both high and low viscosity plastic melt through the system. Specially designed low-compression teeth allow the MGP class transfer, booster or metering gear pump to achieve both high pressure and low shear. The plastic melt is conveyed with a constant, precise flow even at high discharge pressures — and this also for low viscosity products like prepolymers, where former pump generations  reached their limits. Additionally, their high efficiency and long service life will enhance the capacity of any given production plant.
