7. Technical data

7.1 Operating conditions

7.1.1 Liquid temperature

The maximum liquid temperature depends on the
temperature class specified by customer and the
shaft seal.

T2
T3
T4
T5
T6
The illustration below shows the maximum surface
temperature of the pump as a result of maximum
liquid temperature and temperature rise in the shaft
seal.
Fig. 11 Calculation of maximum surface
temperature
The maximum surface temperature of the pump must
be at least 5 °C lower than the maximum surface
temperature of the temperature class specified by
the customer.
The maximum liquid temperature and the
temperature class specified by the customer are
stated on the "key application data sheet" supplied
with the pump. See the example at the end of this
document.
A copy is filed by Grundfos and can be traced by
means of the product number and serial number on
the pump nameplate.

Do not exceed the maximum liquid
temperature or pump another type of liquid
than those specified on the "key
application data sheet" supplied with the
pump. Damage resulting from disregarding
this warning will not be covered by the
Grundfos warranty.
If the "key application data sheet" is
missing, contact Grundfos for information
about the maximum liquid temperature.
If the pump is to be operated at a higher
liquid temperature, or with another liquid
than the one stated on the data sheet,
contact Grundfos.

7.1.2 Ambient temperature

The ambient temperature range in operation is -20 to
+60 °C for the pump-end.

8. 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.
