Best suited for proportional dosing control by use of control motor

● The CM-Y is a pump designed with a special-shaped cam and a two-stage check valve structure on the discharge side, enabling the discharge volume to maintain linearity down to the minimum level.
It must be the most suitable for chemical dosing if the input, such as flow rate and water quality, would fluctuate much. In this 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)

● Since it can be equipped with the specified manufacturer’s increased-safety explosion-proof motor or a pressure-resistant explosion-proof motor, it can be used safely even in hazardous environments.
● Other inverter motors and VS motors, among other leg-mounted motors, can also be attached to a common base via coupling connection.

● 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.
When your pump is of the standard specifications, use it in the ambient temperature range of 0-40℃, the liquid temperature range of 0-50℃ and about 0.06MPa Abs. of NPSH req.
