4-16 Fuel Transfers - Cont'd.
5.
When transfer is complete, close valve V3SJ and promptly shut down pump P3J.
6.
Record meterMS1H reading.
7.
Close all other valves.
WARNING
DRY PUMP SUCTION
Do not continue pumping after tank is empty. A dry suction can ruin the pump.

Transfer Fuel from a Secondary Module Tank to the Associated System
To transfer fuel from the TPT to the associated pipeline, there must be no back pressure in the pipeline system that
exceeds the 600 gpm hoseline pump's ability to supply. The relative pressure situation will vary with the specific system
and cannot be fully described here for a typical installation. The 600 gpm hoseline pumps are restricted to a discharge
pressure of 150 psig. The hoseline system is restricted to 150 psig maximum pressure. Assuming the specific
installation and its associated pipeline system are set up such that this can be done, the operating instruction for
transferring fuel from tank T1J via pump PIJ to the associated pipeline system is as outlined below. The routing from
other secondary module tanks. T2J, T3J, or T41, is similar except for valve positions and can be readily determined
from P&ID flow diagram, Fig. 4-1.
1.
Open valves V61. V7J, V11J. V12J, V13J, and V34J.
2.
Record reading or reset meter MS1H.
3.
Start and operate pump P1J at low discharge pressure.
4.
Open V35J while increasing the discharge rate on pump P1J.
5.
When transfer is complete, close valve V35J and promptly shut down pump P1J.
6.
Record reading on meter MS1 H.
7.
Close all other valve
CAUTION
BACK FLOW
Make sure there is no flow from pipeline system into the TPT when the intent is to transfer
fuel from the TPT to the pipeline system.
