USE – STANDARD VERSIONS
Pumping of clean liquids and without solid bodies.
Fluid: chemically and mechanically non-aggressive, with a maximum solid substance content equal to the hardness and grain size of silt.
WARNING!
•
For pumping water / glycol mixtures with different density and viscosity of the water:
o recalculate the pump performance;
o verify the required power to the motor in function of the characteristics of the liquid.
Don’t use the electric pump with liquids with different chemicals characteristics from those of the water ones (demineralized or treated
water, food liquids, dangerous liquids, ecc..) unless you have contacted the techincal assistance before.
Use the pump / electric pump only for the purposes described in this manual. Any other use can be a cause of accidents.
For the special versions, refer to the specific technical literature (technical data, drawings, etc. ...).
The pumps requested and built for pumping potable water should only be used for this purpose. Verify that the pump is suitable for
