Our company's Direct-drive Oil Sealed Rotary Vacuum Pump is the Sliding Vane "Gaede type". It employs oil in the vacuum pump to lubricate the rotary part and to allow sealing effect upon vacuum formation, thus obtaining a high degree of stable vacuum and high reliability. This small direct-drive motor excels over belt-driven types both in quickness of starting and pumping. |

| *Ultimate pressure is measured with Macleod gauge. |
| GLD Series, compared
with G Series, is markedly upgraded. For the sake of having
the maximum performance, in addition to notes for G series,
be careful of also the followings. |
| 1. |
GLD series is capable
of reaching to a high vacuum area (10-2 Pa).
Flanges, vessels usable at a high vacuum are required. |
| 2. |
An oil-sealed rotary
pump is not recommended for continuous operation near atmospheric
pressure. |
