Description:

?

WORKING CNDITIONS:

1.Liquid temp.:-10°C to +100°C;

2.Ambient temp.:+40 °C;

3.Medium requirement: clean without sundris, mineral oil, stickiness and corrosiveness;

4.Suitable Fluids:

Heating water to VD 12035

Heatina water

Water and ethanol maximum ratio : 1:1

5. Maximum operating pressure : 10bar ;

6. Minimum inlet pressure:

When the temperature is +50°C 0.05 bar ,

When the temperature is +70°C 0.3 bar ,

When the temperature is +90°C 1.0 bar .

?

The above-mentioned values are only aplicable for elevation of 300m; as for the higher elevation, 0.01bar should be added for every 100m increased.To prevent noise generated by cavitaion erosion, the minimuminlet pressure should be maintained.
