How to operate the frequency for the pump motor?

图片
 On the motor nameplate provided by  BONVE  Rotary Lobe Pump , we can see two frequency ranges: 1. Constant Torque Frequency Range: 5-50Hz 2. Constant Power Frequency Range: 50-100Hz How to understand them and use them into your operating? Constant Torque Frequency Range means that the motor can provide a stable output torque throughout the entire frequency range. This indicates that the output torque of the motor remains unchanged when adjusting the frequency. This is particularly important for rotarylobepumps when handling fluids with increased viscosity due to temperature decrease, as higher viscosity requires lower suitable speeds. Constant Power Frequency Range means that the output power of the motor remains constant across the entire frequency range. Regardless of the adjusted frequency (speed), the motor maintains a consistent output power. In rotarylobepump applications, constant power frequency allows for better dynamic response to meet the flow rate and pressure requirements
