Product Description

The DRV series pumps are compact, low noise, two-stage, oil-sealed, high-vacuum 
pumps designed for reliable, long-term operation in both laboratory and industrial 
environments. A four-pole three-phase motor provides direct-drive through a flexible 
coupling.
The pump body is easy to disassemble without special tools.
The pump cavity is divided into several spaces by a rotor eccentrically installed in the 
pump cylinder and two rotary vanes in the rotor groove, and the volume of each space 
changes periodically with the rotation of the rotor. When the rotor drives the vanes to rotate, 
the rotary vane sticks to the cavity wall by centrifugal force and the elastic force of the air 
spring, separates the intake and exhaust ports, and makes the volume of the intake cavity 
periodically expand and inhale, and the volume of the exhaust cavity is Periodically shrink 
and compress the gas, and use the compressed gas pressure and oil to push the exhaust 
valve plate to exhaust, thereby obtaining a vacuum.
