13.1.8 Shaft seals
The operating range of the seals is described for two
main applications: Pumping of water or pumping of
coolants.
Seals with a temperature range of 0 °C and up are
mainly used for pumping water, while seals for
temperatures below 0 °C are mainly intended for
coolants.
We do not recommend that you operate
the pump at maximum temperature and
maximum pressure at the same time as
the seal life will be reduced and periodic
noise will occur.
