8. Operating conditions
Warning
Do not operate the pump at any pressure, flow
rate or liquid temperature other than those for
which the pump was originally purchased. Do not
pump any other liquid than the one for which the
pump was originally purchased without the
consent of Grundfos or its authorised
representatives. Disregard of this warning can
result in pump failure and serious personal injury
or death.
8.1 Minimum inlet pressure
At any time, there must be a positive inlet pressure. A minimum
inlet pressure of 5 psi is recommended.
Inadequate inlet pressure will result in cavitation
Caution
damage to the impeller and casing.
8.2 Maximum inlet pressure
The sum of actual inlet pressure plus pump pressure against a
closed valve must always be lower than the maximum
permissible operating pressure. See section 8.7 Maximum
operating pressure. The maximum inlet pressure is 100 psi
(approx. 7 bar).
8.3 Minimum flow rate
Generally, the pump is not allowed to run against
a closed valve, as this may cause an increase in
Caution
temperature or formation of steam in the pump.
This may cause damage to the pump.
Only brief periods of operation during start and stop are
permissible with a closed discharge valve. Prolonged operation at
less than 15 to 20 % of the pump's rated capacity will cause
heating of the pumped liquid, impeller erosion, short life of
bearings and packing due to stress or vibration. Some pumps
may incur shaft damage and wear on stationary parts.
It is therefore advisable to install a bypass pipe to ensure a
minimum flow rate of at least 2 % at maximum efficiency. The
minimum flow rate helps to dissipate any excessive heat and thus
protect the pump against overheating.
Operation of the pump with flow only through the
Caution
bypass is not allowed.
How to install a bypass is shown in section 9.6 Bypass.
8.4 Pumped liquids
The pumps are suitable for clean and non-aggressive water, not
containing solid particles or fibres.
8.5 Liquid temperature
Maximum permissible liquid temperature is 40 °C. The pumps
can handle temperatures from 0 °C to +120 °C.
8.6 Pump speed
The maximum pump speed is stated on the test report and shown
on the nameplate for the fire pump set. See fig. 15, pos. 11.
8.7 Maximum operating pressure
10, 16 or 25 bar.
The maximum operating pressure is stated on the pump
nameplate.
