Installation, Operating and Maintenance Instruction
3.3.2 Oil Sump Cooling
On temperatures of the pumped liquid over 180°C an
oil sump cooling is required.
For connection refer to list "Connections" in the annex.
For cooling use pure, non-aggressive water with a
maximum incoming temperature of 30°C.
Cooling water should be hand-warm at discharge.
The pressure in the cooling system must not
exceed max. 6 bar.
Provide control devices for temperature and
pressure monitoring.

3.5 Permitted Nozzle Loads and Torques
at the Pump Nozzles ...
... following the Europump-Recommendation for
pump acc. to ISO 5199.
The data for forces and torques are only valid for static
piping loads.
The values given in the chart are valid for pump units
with standard LS- or LCP-base frames (grouted).
The data for forces and torques refer to LC or LCP-
standard materials 0.7040 (ductil iron) and 1.4408
(stainless steel).
For the LS-standard material 0.6025 (cast iron) the
values must be multiplied with factor 0,5.
