5 Maintenance
5.1 Daily maintenance
Regularly check the outlet pressure.

No water should get into the terminal box of the electric motor when the
pump room is sprayed clean! Never spray water on hot pump parts! The
sudden cooling down may cause them to burst and hot water may flow out!
5.2 Service liquid
After the pump has been put into operation once, the working-liquid tank and the float-
controlled de-aerator don't have to be filled up again: there is constantly a sufficient
quantity of pumped liquid in the working-liquid tank and the float- controlled de-aerator.
5.3 Shaft sealing
5.3.1 Mechanical seal
A mechanical seal generally requires no maintenance, however, it should never be
allowed to run dry . If there are no problems, do not dismantle the mechanical seal. As
the seal faces have run in on one another dismantling usually implicates replacement of
the mechanical seal. If a mechanical seal shows any leakage it has to be replaced.
5.3.2 Lip seal
The lip seals generally require no maintenance. The lip seals run around stainless steel
shaft sleeves which are provided with a hard wearing layer. The space between the lip
seals is filled with grease when they are mounted, so as to limit wearing to a minimum.
When the lip seals are leaking they have to be replaced.
5.4 Lubrication of the bearings
The bearings have to be re-greased after every 1000 hours of operation. The bearings
are greased before delivery. In case the pump is overhauled, the bearings and the
bearing house have to be cleaned and provided with new grease. See paragraph 10.1
"Recommended greases" for recommended greases and quantities to be applied.
