There is actually a limit to the speed of a pump, which mainly depends on the process fluid. If oil is being transported, the pump can rotate at a high speed. However, when the fluid is a high viscosity polymer melt, this limit will significantly increase.
It is very important to push the highly viscous fluid into the two tooth space on the suction side. If this space is not fully filled, the pump cannot discharge accurate flow, so the PV value (pressure × Flow rate is also another limiting factor and a process variable. Due to these limitations, gear pump manufacturers will provide a range of products with different specifiions and displacement (the amount discharged per revolution). These pumps will be combined with specific appliion processes to achieve optimal system capacity and price.
