※1 Designed Pumping Capacity: Theoretical value calculated from cylinder volume. Refer to “Performance Data” for actual flow rate.
※2 Pump can be continuously operated at the maximum ultimate pressure.
※3 Operating noise level measured on new pump with ORION recommended motor running under normal conditions
※ Please consult your dealer regarding continuous operation at levels on the dotted lines in the performance data charts.
※ Maximum operational pressure variation pulse: 13.3 kPa [abs]
※ When ducting off exhaust, allowable back pressure from piping is 10 kPa (This pressure should not be used for any purpose)
※ Allowable ambient (intake air) conditions: temperature: 0~40°C, humidity: 65 20%
※ Due to high compression ratios, condensation is easy to form within high-vacuum pumps. Therefore the following measures should be taken to avoid trouble from rust due to condensation: During a trial run (operation of 5 minutes or less, such as momentary operation or a short test run) if the operating pressure goes above 48kPa[abs], then a dry run of 10 to 15 minutes should be made at a pressure of 48kPa[abs] at the vacuum side of the pump.
※ Allowable variation in power source voltage: 10% of rated voltage.
※ Install overload protection such as a thermal overload relay. Set the relay to the current rating specified on the motor nameplate.
※ Single phase models require pre-order. ※See specification sheet for further details.
