Products Description

Gear pumps control the output of the screw to the die. Gear pumps use a set of rotating gears to control the melt pressure and output volume to the die within very tight tolerances (< 1%) with little or no pulsation of the melt flow. This isolates the die from any upstream fluctuation such as surging in the screw area due to material or machine variations.

A gear pump has many advantages due to the gear mechanism being finished with close tolerances providing a highly efficient performance in terms of suction and discharge. The nature of the gear teeth and powerful motion makes it exceptional at handling viscous fluids up to 100,000cps including chocolate, fats, oils and similar.

Although the pump does handle solids and abrasive material well, the pump can handle shear sensitive fluids with a gentle non-pulsating flow thanks to the cumulative, smooth delivery of the gear teeth meshing. The flow is directly proportional to the speed, independent of the pressure, giving much greater control and reliability to the service operator.
