START UP CHECK LIST
1.
Check alignment and connections of all piping/tubing to the pump. Pipes must be supported
to prevent drop down or pressurized recoil when the pump flanges or unions are disconnected.
2.
Inspect complete piping/tubing system ensuring that no external piping loads are being placed
on the pump.
3.
Secure appropriate hose connections.
4.
Check all nuts and bolts, flanges, and base mounting fixtures for tightness.
NOTICE:
If difficulties or issues are experienced dur-
ing start up, please consult the
“
General
Pump Troubleshooting
”
section.
NOTICE:
“
Dry running
”
the pump WILL result in gear
and pump damage.
START UP PROCEDURES
1.
Ensure appropriate valves are open in the inlet and discharge lines.
2.
Start the pump. Priming should occur within one minute.
3.
Inspect all associated piping, fittings and system equipment for issues such as leaks, noise, vibration
and overheating.
4.
Check flow rate to ensure the pump is operating within expected limits.
5.
If equipped, check the relief valve pressure setting by momentarily closing a valve in the discharge
line and reading the pressure gauge. This pressure must be a minimum of 20
-
30 psi (1.4
-
2.1 Bar)
higher than the maximum system operating pressure or pressure relief plate setting, and must not
exceed 150 psi.
DO NOT operate the pump against a closed discharge valve for more than 15
seconds.
If adjustments need to be made, refer to the
“
Relief Valve Setting and Adjustment
”
sec-
tion of this manual.
NOTICE:
The range of temperatures that pump sur-
faces will develop is dependent upon fac-
tors such as product temperature and am-
bient temperature of operation. There
may be instances where the external pump
surface can exceed 50°C. In these situa-
tions, proper warnings/guards MUST be
used.
PUMP OPERATION
Pumps operating against a
closed valve can cause system
failure resulting in personal
injury and property damage
Pumping hazardous or toxic
fluids can cause personal injury
and property damage.
NOTICE:
High Viscosity fluids and / or low fluid lev-
els will lead to high suction at start up.
This will cause a
“
dry run
”
situation. The
pump must be adequately primed by add-
ing fluid to the inner pump area through
drain plug openings in the back plate.
Disconnecting fluid or pressure
containment components dur-
ing pump operation can cause
serious personal injury, death
or major property damage.
