ORION Heavy Duty KRF Series


1 Models without motors are excluded.

2 Designed Pumping Capacity: Theoretical value calculated from cylinder volume. Refer to Performance Data” for actual flow rate.

3 Operation not allowed at ultimate vacuum.

4 Range of operable degree of vacuum (or exhaust pressure)

5 “04” models are special order items.

6 Operating noise level measured on new pump with ORION recommended motor running at normal vacuum/pressure conditions. Allowable ambient (intake air) conditions: temperature: 0 40 , humidity: 65 20%. Allowable variation in power source voltage: 10% of rated voltage. Install overload protection such as a thermal overload relay. For specific setting of the relay, refer to current rating indicated on the motor’s specification plate. Set at 110% of the rated value for B and VB models. See specification sheet for further details.
