FTA550 Jockey Pump Controllers

The FTA550F Jockey Pump Controller utilizes
across the line, full voltage starting. Full voltage
is applied to the motor as soon as the controller is
actuated, and the motor supplies its rated torque.
When the controller is actuated, either by a
drop in system pressure (in the “Auto” mode), or by
placing the HAND-OFF-AUTO switch in the “Hand”
position, the pump will start. In the “Auto” mode,
the pump will continue to run until the pressure
returns to a normal level and the minimum run
timer has expired, whichever occurs last. In the
“Hand” mode, the pump will continue to run until
the HAND-OFF-AUTO selector switch is moved
from the “Hand” position.
The stainless steel pressure transducer is
mounted inside the enclosure and is piped to a fi t-
ting on the bottom of the enclosure.
