Installation
Fig. 4:
Filling with lubricant
Screw in lubricant filler screws 15.
Check lubricant level when the pump is running at operating temperature in final vac-
uum:
– Fill level during operation: as per the sight glass image.
– Check fill level during continuous operation on a daily basis, otherwise each time
the pump is switched on. To add lubricant, switch off the pump and vent it to atmo-
spheric pressure.
Filling the sealing oil
chamber
The shaft feedthrough of the drive shaft is sealed with sealing oil-covered radial shaft
seals, and is fed by an oiler 18. The type of sealing oil is the same as the lubricant.
Fill up oiler to halfway with lubricant.
– Oiler 18 should always be filled to a max. of halfway (when the pump is cold); top
up as required.
Adding sealant for
the mechanical seal
(versions with MS
only)
When using a mechanical seal (optional), a cooling of the sealing surfaces is required.
The sealant reservoir needs to be attached above the shaft feedthrough on the outside
of the pump, on the base frame or in a different suitable location depending on the actual
conditions. The mechanical seal is capable of bridging a certain pipe resistance through
its own pumping effect. If the supply of sealant is no longer guaranteed, an additional cir-
culation pump must be installed. The pipes and the sealant reservoir are not contained
in the scope of supply.
During assembly of the sealant reservoir observe the installation instructions supplied
by the manufacturer.
Use the sealant in accordance with the manufacturer's instructions.
Cooling the mechanical seal
The ambient temperatures to which the pump is exposed will vary depending on the lo-
cation in which it is being used. If the cooling of the sealant (max. +90 °C) is not sufficient
for the amount of heat radiated at the sealant reservoir, then an additional water cooling
system (25) will need to be connected.

WARNING
Toxic vapours!
Danger of poisoning when igniting and heating synthetic operating fluids (e.g. F4/F5)
above 300 °C.
Observe the application instructions.
Do not allow operating fluid to make contact with tobacco products; observe safety
precautions when handling chemicals.
The lubricant expands when the pump heats up, which could cause lubricant to
leak if the oiler is overfilled.
