Features

CMD series works two diaphragms operated by one motor.
The comparison features between CM series and CMD series as follows.

● The discharge rate of CMD series is twice of model CM series.

● 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.
When your pump is of the standard specification, use it in the ambient temperature range of 0-40℃, the liquid temperature range of 0-50℃ and_ about 0.06MPaA (0.6kgf/cm2A) of NPSH req.
◯The maximum discharge rate of CMD-3G to 12G at the maximum discharge pressure should be at 1.0MPaG of the pressure.
