In principle, the rotary lobe pump can only be selected based on the basic selection of working pressure and total flow, purchase order, viscosity, temperature, pH, solid water content and other actual operating standards, so as to minimize the operation exceeding the limit of the standard in work. When the viscosity of raw materials, When the increase in total flow and working pressure is very likely to cause the motor to be loaded, be sure to check the air pressure gauge, valve and overcurrent protection device frequently.
