Oil Sealed Screw Vacuum Pump

  OSV series energy-saving oil-injected screw vacuum pump adopts a new generation of screw profile, the screw rotor tooth profile accuracy is better than others in the industry, and it operates under light load. 

  Extraordinary one-piece screw main engine structure, motor direct drive, no transmission loss, early 100% transmission efficiency. Vector frequency conversion control, quick response, reasonable distribution of current value, and more excellent torque enhancement effect.

The OSV oil-injected screw vacuum pump adopts a permanent magnet variable frequency dedicated motor, which greatly improves the efficiency of the drive motor and thus achieves energy saving.

·Using high coercive force, high temperature resistant permanent magnets, ensuring no demagnetization at 150°C; ultra-large torque design,

·Stepless speed change, wide frequency speed regulation range, easy frequency conversion control, good dynamic response performance, can quickly respond to large-scale adjustment, and can also accurately adjust the vacuum degree;

·Frequency conversion adjustment start, smooth start, reducing the impact on the power grid;

·Super energy efficiency, motor efficiency is as high as 98% or more, in line with the IES level of IEC60034-30-1:2014 'Variable Speed AC Motor';

·Power factor is more than 98%, reducing the pressure on the customer's power grid
