The EU VFD (Variable Frequency Drive) series pumps are single-stage oil rotary vane vacuum pumps with oil recirculation system. They are provided with Variable Frequency Drive with protection class up to IP65.
The Variable Frequency Drive can be customized according to different needs and ensures the possibility of modulating the motor revolutions, through frequency control, always offering the vacuum level required by the application, avoiding energy waste and maximizing pump performance.
It is possible to position the Variable Frequency Drive in different configurations, depending on the needs:
• Integrated with the pump, directly on the electric motor (option available from size 105 m³/h to 300 m³/h).
• On board pump: suitable for use in the most demanding environments, thanks to the high degree of protection (IP 65).
• Directly integrated within the electric control panel of the customer’s machine.
