 | | | Itisatype applicable for the voltages all the world, foramulti-voltagemotor is equipped to GLD series. 2 types,forsingle/three phase,are available.
As it is applicable for various voltages by a simplewiringchange,there is no necessity to change the motor for useinaccordance witha voltage in the countries where the pumpisused.
For the single phase, it is used at 100V-120V or200V-240V.Thefunctional performance such as gas-ballast mechanism,oilback-flowprevention mechanism, large-sized oil-level gauge, etc.isequal toGLD Series. It isCEself-declaredproducts. |

 Caution |
| GLDSeries,compared with G Series, is markedly upgraded. For thesakeofhaving the maximum performance, in addition to notes forGseries,be careful of also the followings. | | 1. | GLDseriesiscapable of reaching to a high vacuum area (10-2 Pa). Flanges, vessels usable at a high vacuumarerequired. | | 2. | Anoil-sealed rotary pump is not recommended forcontinuousoperationnear atmospheric pressure. |
