PRE-START UP CHECK LIST
1.
Check the alignment of the pipes to the pump. Support
pipes so that they do not spring away or drop down when
pump flanges or union joints are disconnected.
2.
Verify proper coupling alignment.
3.
Blackmer helical gear reducers (if supplied) are shipped
from the factory without oil in the gearcase. Fill with the
grade of oil indicated on the reducer tag. For more
specific instructions on Blackmer gear reducers, refer to
the appropriate Gear reducer Installation, Operation and
Instruction Manual.
4.
Check the entire pumping system to verify that the proper
inlet and discharge valves are fully open, and that the
drain valves and other auxiliary valves are closed.
5.
Install vacuum and pressure gauges on the pump in the
1/4" NPT connections provided. These can be used to
check actual suction and discharge conditions after pump
start-up.
6.
Check the wiring of the motor, and briefly turn on the
power to make sure that the pump rotates in the direction
of the rotation arrow.

START UP PROCEDURES
Consult the "General Pump Troubleshooting" section of
this manual if difficulties during start up are experienced.
1.
Start the motor. Priming should occur within one minute.
2.
Check the vacuum and pressure gauges to see if the
pump is operating within the expected conditions.
3.
Check for leakage from the piping and equipment.
4.
Check for excessive noise, vibration or overheating of the
pump, reducer, and motor.
5.
If possible, check the flow rate.
6.
Check the pressure setting of the relief valve by briefly
closing a valve in the discharge line and reading the
pressure gauge. This pressure must be at least 15 - 20
psi (1.0 - 1.4 bar) higher than the maximum operating
pressure.
CAUTION: Do not run the pump for more than 10-15
seconds with the discharge valve completely closed.
If adjustments need to be made, refer to "Relief Valve
Setting & Adjustment."
Incorrect settings of the pressure relief
valve can cause pump component
failure, personal injury, and property
damage.
Hazardous pressure
can cause personal
injury or property
damage
RUNNING THE PUMP IN REVERSE
ROTATION
Do not operate the pump 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 run the pump in reverse rotation for
system maintenance. The pump will operate satisfactorily in
reverse rotation for a LIMITED time, at a reduced
performance level.
