Capacity: Design displacement, logic value is calculated from the cubic volume. The actual flow rate refers to the actual measurement data of performances.
The usable range of the degree of vacuum/blower pressure.
For the intake air, use clean air of normal temperature and normal humidity whenever possible.
Intake air condition: Temperature 0 to 40℃ and Humidity 65%RH±20%.
The allowable variation range of the supply voltage should be ± 10% of rated voltage.
Install an overload protector (thermal relays, etc.) Setting value: Use the rated current value which is indicated on the specification plate of the motor, 110% at 50Hz, 120% at 60Hz.
Check availability to Kumark, if operating Orion vacuum pumps with 60Hz condition.

A rotor is placed eccentrically within a cylinder. All components are precisely manufactured and adjusted to achieve minimum clearances. Vanes are inserted into slots in the rotor and are free to slip in and out within the walls of the cylinder. As the rotor turns, the vanes slide out and are kept in constant contact with the cylinder wall due to centrifugal force.
As the rotor turns, the volume of space between the vanes changes. As shown in the illustration, when the rotor spins from state 1 to 2, the increase in volume at the intake creates a vacuum. As the volume of space between the vanes decreases during the cycle, the air trapped between the vanes is compressed as shown between states 2 and 3. Finally between states 3 and 4 the compressed air is allowed to escape through the air outlet. The process repeats as the rotor continuously rotates in order to achieve a constant air flow from inlet to outlet.
A four-vane-type pump provides intake/discharge 4 times in a single rotation. Defining volume at the end of intake as V (L), and rotation speed as N (rpm), 4VN (L) of air is discharged per minute. This theoretical value is what's known as the designed pumping capacity.
