Liquiflo FTS Transfer Pump User Manual
Series Nos. FTS150 and FTS200
General operation procedures
The FTS150/200 pump is a positive displacement pump –
never dead head the pump (operating against a closed
valve or plug). If the Transfer Pump is being used for a
dispensing application, a bypass valve must be installed in
correct position – see page 13. The FTS150 and FTS200
pumps are reversible. The performance in Direction 1 –
Forward (clockwise) is the same as the performance in
Direction 2 – Reverse (counterclockwise).
Flushing the Transfer Pump
1. Purge the suction and discharge lines – The Transfer Pump can be run dry, so there is no danger of damaging it
if the pump is used to clear the lines.
2. Safely isolate the fluid media source once the suction and discharge lines are purged.
3. DO NOT CLOSE ANY DISCHARGE VALVE(S) WHILE THE PUMP IS OPERATING. This will cause a DEAD
HEAD condition in the pump and will result in immediate damage to the pumping mechanism.
Storage
If the unit is not going to be installed immediately, it should be stored indoors, covered with a waterproof sheet, and
with all open ports plugged. If long-term storage is expected (six months or more), it is recommended that the pump
be completely filled with a clean, non-corrosive fluid to prevent the entry of moisture. Acceptable fluids are commonly
available hydraulic oils or oil-based lubricant fluids. DO NOT USE WATER.
4
The standard internal bypass valve will not relieve
pressure when operated in the reverse direction. For
proper pressure relief/bypass in reverse operation, an
external bypass must be installed to relieve pressure
when the discharge side of the pump is blocked or
closed.
