INSTALLATION
ALIGNMENT – FLANGE MOUNTED GEAR
REDUCER
If the unit is assembled with a Blackmer Flange Mounted
Gear Reducer, no coupling alignment is required. The motor,
gearbox, and pump are rigidly connected with bolted, flange
connections. These flanges ensure the motor shaft, gearbox
shafts, and pump shaft are aligned correctly, without the
need for manual alignment. However, due to variations in
base and foundation geometry the unit will require shimming
to reduce stress on the gearbox and pump adapter. See
PRESTART CHECKLIST
section for details.
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.
TO REVERSE PUMP ROTATION
To reverse rotation, the pump must be disassembled then
reassembled with the shaft on the opposite side of the pump.
See the ‘Maintenance’ section for instructions.
CHECK VALVES
The use of check valves or foot valves in the supply tank is
not recommended with self-priming, positive displacement
pumps.
If the possibility of liquid backflow exists when the pump is
off, a check valve in the pump discharge piping is
recommended because the pump can motor in the reverse
rotation and create undue stress on all attached components.
Never start a pump when it is rotating in the reverse rotation
as the added starting torque can damage the pump and
related equipment.
OPERATION
Operation without guards in place can
cause serious personal injury, major
property damage, or death.
Do not operate
without guard
in place
Disconnecting fluid or pressure
containment components during pump
operation can cause serious personal
injury, death or major property damage
Hazardous pressure
can cause personal
injury or property
damage
Failure to relieve system pressure prior
to performing pump service or
maintenance can cause personal injury
or property damage.
Hazardous pressure
can cause personal
injury or property
damage
Pumps operating against a closed valve
can cause system failure, personal
injury and property damage
Hazardous pressure
can cause personal
injury or property
damage
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. Verify proper coupling alignment on long coupled units.
3. For units assembled with a Blackmer Flange Mounted
Gearbox:
3a. Bolt down the pump foot, while supporting the motor
with an appropriate lifting device (e.g. crane)
3b. Place a .125” thick shim under each of the motor
mounting
holes
3c. Slowly lower the motor until it is unsupported
3d. Try pulling out each of the shims, while noticing the
the pull tension
3e. If the shims closest to the motor shaft easily pull out,
increase the shim thickness the same at all
locations and recheck
3f.
If the shims furthest from the motor shaft easily pull
out, decrease the shim thickness the same at all
locations and recheck
3g. The unit is properly shimmed when all 4 motor
shims have the same amount of tension when
pulled
3h. Bolt down the motor with the appropriate fastener.
4. Blackmer Flange Mounted Gearboxes will be shipped
with Mobil SHC630 synthetic oil. If replacing the oil,
refer to the
FLANGE MOUNTED GEAR REDUCER
MAINTENANCE
section.
5. 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.
