<Smallest pump among CM series>
CM-V behaves accurate discharge performance although it is small type using 25W _and 60W motors.

<Various power source specifications>
● Various power source motors lined up as standard _and semi-standard.
・100V  ・110V  ・200V  ・220V  ・230V
・380V  ・400V  ・415V  ・440V
● Totally-enclosed fan-cooled (TEFC) outdoor flange type motor. Take measures such as using the motor cover of standard accessory for outdoor use.
* Consider the installation so as not to expose the pump to the sun.
* It is not available to the explosion-proof requirement.
* It is not applicable to the specified color painting.

<Variety of standard accessories>
A sight glass is standardly equipped for the pump body. (for hose connection of CM-1V-25V, except for XV46 specification, flange and union connections)
A motor cover and simple tools are attached to all models.
An air extract valve, check valve and foot valve are attached to the hose connection of CM-1V-25V-VVFC/VVE4 with sight glass.
Motor cover, air extract pump, simple tools, check valve (only for hose connection), foot valve (only for hose connection)
