7.3.2 Startup
If an outlet valve is installed, we recommend that you open the
valve 1/4 of a turn when starting the pump or the system.
Do not operate pumps against a closed valve.
To start up a BMS hp pump, proceed as follows:
1. Start the feed pump (1), and check that the inlet pressure (2) of
the BMS hp pump (6) is higher than 0.5 bar (6" BMS hp) or 1.0
bar (8" BMS hp).
2. Vent the pump.
3. Start the pump.
4. Ramp up the pump according to factory settings. See the figure
below (1).
Ramp up from 0 to 1700 rpm within three seconds.

Ramping up, BMS hp
Ramp-up time:
• Ramp-up: from 0 to 1700 rpm, maximum 3 seconds.
• Ramp-up: from 1700 rpm to maximum speed, to be
configured by the customer.
• Ramp-down: from maximum speed to 1700 rpm, to be
configured by the customer.
• Ramp-down: from 1700 to 0 rpm, maximum 3 seconds.
5. Set the outlet pressure of the pump to the desired value.
6. Check that the inlet pressure of the pump is higher than 0.5 bar
(6" BMS hp) or 1.0 bar (8" BMS hp) and lower than 82.7 bar.
Make sure that the BMS hp pump is protected against dry-
running.

Operating limits
We recommend that you always keep the capacity of the booster
systems within the recommended flow rate and pressure range of
each individual pump.
Note that if there is a risk of exceeding the maximum inlet or outlet
pressure, we recommend that you install a safety valve.
