distance of 1 m [3.28 ft] with moderate
throtteling (8 kPa abs. [1.16 psia]) and lines
connected.

Operating speed
See rating plate.
NOTICE
Exceeding of the operating speed will
negatively affect the operating behavior of the
pump-motor unit:
 higher
noise emissions
 stronger vibrations
 shorter grease consumption time
 reduced bearing change interval
To prevent damage due to excessively high
speeds, it may be necessary to request the
limit speed
(inquire with the Service
Department).
Tightening torques
The values specified here for tightening
torques apply unless other values are
indicated.

data

3.3 Operating
conditions
Temperatures
Temperature of pumped gases/vapors:
max. +110 °C max. +230 °F
At higher fluid temperatures, measures must
be taken on the system to prevent burns, e.g.
mount separating safety device (cover).
In addition, we also recommend one of the
following measures at temperatures > 80 °C
[> 176 °F]:
 Increasing the operating-liquid flow rate by
up to twice the rated liquid flow rate (cooling
circuit)
 Use of a series capacitor
