Chemical Pump
CM-Y series (Motor driven medium-capacity linearity dosing pump)
Features
Best suited for proportional dosing control by use of control motor
* This pump is designed to keep the discharge linearity at the lowest limit by adopting special type of gear reduction and double-check system at the discharge side. It must be the most suitable for chemical dosing if the input, such as flow rate and water quality, would fluctuate much. In such case, select the proportional dosing control of stroke adjustment by use of control motor.
Refer to Control motor CMK.
Various power source specification
* Various power source motors lined up as standard and semi-standard.
?200V 220V 380V 400V 415V 420V 440V
* Totally-enclosed fan-cooled (TEFC) outdoor flange type motor.
Possible to be equipped with a safety-increase explosion-proof motor, a pressure and explosion-proof motor (coupling connection)
* The pump can be equipped with a safety-increase explosion-proof, a pressure and explosion proof motor, to be used in dangerous condition without anxiety, and with an invertor motor, VS motor, etc. by coupling connection on a common base.

* Since chemical resistance of material varies according to temperature and concentration of fluid, the above applicable chemicals are basic examples.
* Since there are two kinds of connection hose for VVF combination, for selection, specify a chemical name or hose size to be used.
