10. Technical data
10.1 Operating conditions
10.1.1 Operating mode
The pumps are designed for intermittent operation
(S3). When completely submerged in the pumped
liquid, the pumps can also operate continuously
(S1).
10.1.2 Maximum solids size
10.1.3 Installation depth
Maximum 10 m below liquid level.
10.1.4 Operating pressure
Maximum 6 bar.
10.1.5 Number of starts per hour
Maximum 30.
10.1.6 pH value
Pumps in permanent installations can be used for
pumping liquids with a pH value between 4 and 10.
10.1.7 Liquid temperature
0-40 °C.
For short periods of maximum 15 minutes, a
temperature of up to 60 °C is allowed. This applies to
standard versions only.
10.1.8 Density of pumped liquid
When pumping liquids with a density and/or a
kinematic viscosity higher than that of water, use
motors with correspondingly higher outputs.
10.1.9 Sound pressure level
The sound pressure level of the pumps is lower than
the limiting values stated in the EC Council directive
2006/42/EC relating to machinery.
10.2 Electrical data
10.2.1 Power supply
•
1 x 230 V - 10 %/+ 6 %, 50 Hz
•
3 x 230 V - 10 %/+ 6 %, 50 Hz
•
3 x 400 V - 10 %/+ 6 %, 50 Hz.
10.2.2 Enclosure class
IP68, according to IEC 60529.
Insulation class
F (155 °C).
10.2.3 Winding resistances
The table values do not include the cable.
Resistance in the cables: 2 x 10 m, approx. 0.28
Ω
.
10.2.4 Pump curves
Pump curves are available via www.grundfos.com.
The curves are to be considered as a guide. They
must not be used as guarantee curves.
Test curves for the supplied pump are available on
request.
