Note 1)  The discharge rate and the total head are values when each model is tested at a dynamic viscosity of 1 mm

2

/s (the same viscosity as fresh 

water at normal temperature).

 

Basically, the above models cannot be used for pumping water. However, contact Teral Inc. for our suggestions. 

Note 2)  The rated current in the above table (current value indicated on the pump nameplate) is the recommended preset current value of the protective 

device.
