PRE-START UP CHECK LIST
1. Check the alignment of the pipes to the pump. Pipes
should be supported so that they do not spring away or
drop down when pump flanges or union joints are
disconnected.
2. Inspect complete piping system to ensure all valves and
fittings are in their start up or operation positions.
3. Ensure all electrical connections are correct and tight.
4. Jog the pump motor to ensure free rotation, in the correct
direction.
START UP PROCEDURES
NOTICE:
Consult the "troubleshooting" section of this manual if
difficulties are experienced during start up.
1. Start the motor. Priming should occur within one minute.
2. Check the vacuum and pressure gauges installed on the
pump to ensure the pump is operating within the
acceptable parameters. Record the gauge readings in the
"Initial Pump Start Up Information" section.
3. If possible, check the flow rate to ensure the pump is
operating within expected parameters.
4. Inspect piping, fittings and associated system equipment
for leaks, noise, vibration and overheating.
5. Check the pressure relief setting of the pump relief valve
by gradually closing a valve in the discharge line
momentarily and noting the reading on the pressure
gauge. This pressure reading should be 10-20 psi (.96 –
1.4 bar) higher than the maximum system operating
pressure.
DO NOT run the pump for more than 15
seconds with the discharge valve completely closed.
If
adjustments need to be made, refer to "Relief Valve
Setting and Adjustment."
PUMP ROTATION
A right-hand pump rotates clockwise with the intake on the
right side, when viewed from the driven end.
A left-hand pump rotates counterclockwise with the intake on
the left side, when viewed from the driven end.
REVERSE ROTATION
NOTICE:
Magnetic coupled pumps should be operated in reverse
rotation for no more than 10 minutes, and only when a
separate pressure relief valve is installed to protect the
pump from excessive pressure.
It may be desirable to operate the pump in reverse rotation for
system maintenance. The pump will operate satisfactorily for a
LIMITED time;
at a reduced performance level.
FLUSHING THE PUMP
NOTICE:
If flushing fluid is to be left in the pump for an extended
time, it must be a lubricating, non-corrosive fluid. If a
corrosive or non-lubricating fluid is used, it must be flushed
from the pump immediately.
1. To flush the pump, run the pump with the discharge valve
open and the intake valve closed. Bleed air into the pump
through the intake gauge plug hole or through a larger
auxiliary fitting in the intake piping. Pump air for 30 second
intervals to clean out most of the pumpage.
2. Run a system compatible flushing fluid through the pump
for one minute to clear out the remainder of the original
pumpage.
3. To remove the flushing fluid, follow step 1 above.
NOTICE:
After flushing the pump some residual fluid will remain in
the pump and piping.
NOTICE:
Properly dispose of all waste fluids in accordance with the
appropriate standards and regulations.
