※1 Designed Pumping Capacity: Theoretical value based on volume. Refer to performance data for actual flow rate.
※2 Pump can be continuously operated at the maximum attainable vacuum.
※3 Actual operating noise measured on a new pump with the ORION recommended motor. Operating noise level is from a position of 1 m in front of the product and at a height of 1 m.
※ Operating Pressure Range: 48 kPa [abs] to Ultimate Pressure
※ Permissible pulsation range: 13.3 kPa/s [abs] or lower
※ Models with ductable exhaust (KHA100A/200A/400A/750A) are also available. Allowable duct resistance: 25 kPa or lower. (Exhaust air should not be used for any purpose.)
※ Operating environment (inlet air) conditions: air temp: 0 to 40 ℃, humidity: normal level (65±20%).
※ Due to the high compression ratios, condensation can easily form within the pump. Therefore the following measures should be taken in order to avoid trouble from rust due to condensation:During a trial run (operation of 5 minutes or less, such as a momentary operation or short test run) if the operating pressure goes above 48 kPa [abs], then a dry run of 10 to 15 minutes should be made at a pressure of 48 kPa [abs] at the vacuum side of the pump.
※ The allowable intermittent power supply voltage fluctuation range is ±10%, and the allowable sustained supply voltage fluctuation range is ±5% of the specified voltage.
※ Please install an overload protection device (such as a thermal relay). Use the current rating listed on the three-phase motor nameplate as a guide when setting the protection device.
