High-Vacuum Dry Pump – Bơm Chân Không Sâu

Direct Drive High Vacuum KHF Series – Dòng Nối Trực Tiếp KHF

• Meets CE certification standards. (04 Models)
• Continuous operation at ultimate pressure.
• Easier vane blade replacement (compared with KHA models.)
• High degree of vacuum, excellent substitute pump for ejectors and electronic component and small parts handlingautomated equipment.

*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 attainable vacuum.

*3 Operating noise level measured on a new pump with the standard built-in ORION motor. Operating noise levels are from a position of 1 m in front of the unit and at a height of 1 m.

* 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] /s.

* Allowable back pressure for exhaust ducting: 10 kPa or lower. (This pressure should not be used for any other purpose.) * Operating environment (inlet air) conditions: air temp: 0 to 40 °C, humidity: normal levels (65±20%). * Due to the high compression ratios found in high-vacuum pumps, 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.

* Allowable intermittent power supply voltage fluctuation range is ±10% of the specified voltage; allowable sustained supply voltage fluctuation range is ±5% of the specified voltage.

* Please install an overload protection device (such as a thermal relay).

* Single phase models require pre-order. * See specifications sheet for further details

*2 Pump can be continuously operated at the maximum attainable vacuum.

*3 Operating noise level measured on a new pump with the standard built-in ORION motor. Operating noise levels are from a position of 1 m in front of the unit and at a height of 1 m. * Working vacuum range: 48 kPa [abs] to ultimate pressure.

* Maximum operational pressure variation pulse: 13.3 kPa [abs] /s. * Models with ductable exhaust available (KHA100A • 200A • 400A • 750A). When ducting off exhaust, the allowable back pressure from the piping is 25 kPa. (This pressure should not be used for any purpose.)

* Operating environment (inlet air) conditions: air temp: 0 to 40 °C, humidity: normal levels (65±20%).
