The design of the GV600 dry pump is based on the GV DrystarR range of vacuum pumps. The higher capacity pump has a displacement of 350 CFM, a peak pumping speed at 0.75 torr at 335 CFM and an improved ultimate pressure of better than 3 x 10-2 torr. The pump is based on the patented "reverse claw" mechanism with an additional roots stage added to enhance pumping speed in the working range, making the pump suitable for backing industrial diffusion pumps without the need for an additional mechanical booster pump. For flexibility of system design and retrofitting, the pump offers two inlet ports.
