DPV Series Oil-sealed Vacuum Pump Advanced Design:

• Profile: Using advanced Y-type line, a wider flow range can be obtained;
• Energy Saving: The operation mode design can avoid the efficiency drop caused by the power factor of the motor when operating at a higher vacuum level;
• Transmission: Coaxial connection reduces energy loss and failure points caused by transmission components;
• High Vacuum: The maximum vacuum degree exceeding 29.9inHg (limit pressure 0.5Torr);
• Efficient Separation: Adopt two-stage separation technology to reduce the loss of lubricating fluid and protect the environment;
• Frequency Conversion speed regulation: Powerful frequency conversion control technology, through flow regulation, maintains the constant vacuum degree of the system and reduces the waste of energy consumption;
• Permanent Magnet Synchronous Motor: The rotor does not need excitation current, which improves the motor etficiency and the energy saving effect is more obvious at low load.

DPV Series Oil-sealed Vacuum Pump Powerful Control System:

• DENAlR screw vacuum pumps can maintain the set point pressure during operation and adjust its speed to meet this vacuum requirement. In this case, compared with the traditional technology, the use of DENAlR vacuum oil seal screw technology can achieve energy saving of up to 30% or more.
