Pump size indicating Rotor diameter : 4 ~ 150
It is a model number related to the diameter of the rotor, and the larger the rotor diameter, the larger the discharge volume.
Pump Size Number (Rotor Diameter φ) |
4 | 6 | 8 | 10 | 15 | 20 | 30 | 40 | 50 | 60 | 69 | 80 | 89 | 100 | 120 | 150 |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Theoretical Discharge Volume per Rotation(cc/rev) |
0.23 | 0.9 | 2 | 3.9 | 14 | 32 | 108 | 256 | 474 | 864 | 1,440 | 2,048 | 2,560 | 4,000 | 6,912 | 13,500 |
The above is for the basic model, and the discharge volume of the low concentration type(K22~K152) is twice of the basic type.
Under the same discharge volume, a small pump may be selected with fast rotation, whereas a large pump shall be selected with slow rotation. It may seem that selection of the small pump with fast rotation is economical, however, the stable performance and durability can be guaranteed by selecting a proper speed of rotations to meet the service liquid and the operational conditions.
Please refer to the pump size number according to the Size and Performance graph.
Number of Stages of Rotor/Stator : None ~ 8
The required number of stages is selected according to the discharge pressure.
Number | Number of Stages | Discharge Pressure (kg/cm²) | Number of Stages is proportional to Discharge Pressure | ||
