For short periods (maximum 1 hour), a temperature of
up to 60 °C is permissible for non-Ex versions.
Explosion-proof pumps
must never pump liquids
with a temperature high-
er than 40 °C.
Ambient temperature
The allowed ambient temperature is -20 to +40 °C.
For explosion-proof
pumps with WIO sensor,
the ambient temperature
at the installation site
must be within 0-40 °C.
Density and viscosity of the pumped liquid
When pumping liquids with a density and/or a
kinematic viscosity higher than water, use motors with
correspondingly higher outputs.
Flow velocity
Keep a minimum flow velocity to avoid
sedimentations in the pipes. Recommended flow
velocities:
•
in vertical pipes: 0.7 m/s
•
in horizontal pipes: 1.0 m/s.
Maximum solids size
From 50 to 100 mm, depending on the pump size.
Maximum starts per hour
Maximum 20 starts per hour.
Noise emission < 70 dB (A)
•
Measurements were carried out on dry-installed
pumps in a closed system.
•
Sound power measurements were carried out
according to ISO 3743.
•
Sound power was calculated at a distance of 1 m
according to ISO 11203.
The sound pressure level of the pump is lower than
the limiting values stated in the EC Council directive
2006/42/EC relating to machinery.
Supply voltage
•
3 × 230 V - 10 % / + 6 %, 50 Hz
•
3 × 400 V - 10 % / + 6 %, 50 Hz.
Safety factor
The motor has a safety factor of 1.1.
Enclosure class
IP68, according to IEC 60529.
Insulation class
F (155 °C).
Disposing of the product
This product or parts of it must be disposed of in an
environmentally sound way.
1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest
Grundfos company or service workshop.
The crossed-out wheelie bin symbol
on a product means that it must be
disposed of separately from household
waste. When a product marked with
this symbol reaches its end of life, take
it to a collection point designated by
the local waste disposal authorities.
The separate collection and recycling
of such products will help protect the
environment and human health.
