Chemical Pump
| single head type | double head type |
CMD-G series (Motor driven medium-pressure medium-capacity dosing pump) double head type
Features
Two diaphragms operated by one motor
* Much discharge rate with the same power (one motor).
* Lessen pulsation by dosing from two pump head to one line.
* Two flow-rate adjustment dials for two pump heads to control each discharge rate independently.
* This pump can be equipped with two different combination of liquid-end material to dose two different fluids by one pump.
* It is possible to keep initial and running costs lower to improve cost merit.
Remark for use
* Both pump heads (diaphragms) shall be the same diameter. It means that both discharge rates shall not be so different.
* Since the driving motor is one, each of the dosing cannot be stopped during operation. Be careful about operation with automatic control such as ON-OFF control by output signal from controllers.

* The discharge rate was calculated at discharge pressure of 0.1MPaG, suction head of -0.01MPaAq equivalent to the same pipe diameter as in the pump; and normal temperature using clear water.
* For use with flange connection, the discharge pressure of CMD-3G to 12G should be 1.0MPaG maximum.
* Discharge rates of CMD series are twice of CM series. There is no hose connection and single-phase motor type for CMD-200G to 700G.

* Since chemical resistance of material varies according to temperature and concentration of fluid, the above applicable chemicals are basic examples. It is possible to combine different materials.
* Aflas is a kind of fluoro rubber.
* Since there are two kinds of connection hose for VVFC combination, for selection, specify a chemical name or hose size to be used.
* If Sight Glass is needed for CMD-3G to 12G, make a special order to equip a pump with it.Do not use CMD-G series for organic solvent
