* 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 should be 1.0MPaG maximum.

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 CM-7Z to 100Z, make a special order to equip a pump with it.

Viscosity of fluid
Refer to the chart below for transfer high-viscous fluid such as Polymer flocculants.

Connection Dia. 6 x 11mm hose 15A flange Liquid-end combination
