VDC poump is an innovative motor direct driven dual-stage oil-sealed rotary vane vacuum pump with brushless DC motor.  The pump is absolutely energy-saving with small motor power design. The feature of low noise level is an ideal choice for high requirements of quiet operation, especially for analytical applications.

BENEFITS:
– Low noise level thanks to brushless DC motor design
– Low power consumption for cost saving
– Low and easy maintenance
– Easy installation
– Small footprint
