Frequently asked questions
What is the maximum pumping speed available in the NeoDry G-Series?
The NeoDry G-Series offers pumping speeds ranging from 110 L/min (NeoDry7G) up to 600 L/min (NeoDry36G).
Can the NeoDry G handle moisture or vapors?
Yes. With the gas ballast option, the pump can tolerate moisture. The maximum allowable moisture (with gas ballast) goes up to 135 g/h, 275 g/h, or 350 g/h, depending on the model.
Is there a gas ballast mechanism?
Yes — the gas ballast mechanism is optional. There’s also an N₂ (nitrogen) model available.
What are the maintenance requirements or schedule?
One highlight is that the maintenance cycle is about once every 3 years (assuming use with air or nitrogen). Also, there is no tip-seal replacement needed, no performance deterioration, no particles, oil smoke, or chamber contamination.
What ultimate pressure can I expect from these pumps?
Without a gas ballast, the ultimate pressure ranges from about 5.0 Pa for the smaller models down to about 0.7 Pa for the larger models.
What voltages are supported?
These pumps are designed for single-phase AC, 100-240 V, 50/60 Hz.
How loud is the NeoDry G-Series?
With the inlet closed, the noise level is between 45 dB(A) and 51 dB(A), depending on the model.
What are the sizes & weight of these pumps?
Mass: from 19 kg up to 51 kg depending on model.
Dimensions (L × W × H) vary roughly between 360×196×196 mm and 475×298×260 mm.
