General operation procedures
• The Transfer 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 to return the discharge flow back to the storage
tank. See Section 3,
Installation and setup, Piping guidelines
for more
information.
• Always ramp the transfer pump up to speed to start up, and down from
rated speed to shut down. See Section 3,
Installation and setup,
for
information on motor control device requirements.
• The FTS300 is reversible. The performance in Direction 1 – Forward
(clockwise) is different than the performance in Direction 2
– Reverse
(counterclockwise) due to the centrifugal boost added by the Transfer
Pump’s impeller. See Pump Data Package for more information.
Shutting down the Transfer Pump
The Transfer Pump should be brought to a stop by decelerating it using the
control device, either a Variable Frequency Drive or Soft Starter. Abruptly
stopping the pump by removing power from the motor may cause premature
failure of the pumping mechanism or a hazardous condition.
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.
WARNING
Disconnect electrical/motive
power to the Transfer Pump
before service.
CAUTION
Be sure all appropriate lock-out/
tag-out procedures have been
followed before performing any
service on the Transfer Pump
and ensure that all appropriate
personal protective equipment
(PPE) is worn at all times. It is
the responsibility of the user’s
qualified personnel to safely
flush and service the Transfer
Pump.
CAUTION
Allow the Transfer Pump to cool
before touching it.
WARNING
Your pumping fluid may be
hazardous
– identify the fluid
and take any appropriate
actions before flushing the
pump.
CAUTION
Your pumping fluid may be
flammable
– identify the fluid
and take any appropriate
actions before flushing the
pump.
