STORAGE PRECAUTIONS
Do not store filled with fluid at or below freezing temp of
process fluid.
INSTALLATION
INSTALLATION FOR CHEMFLO END SUCTION
PUMPS:
MP CHEMFLO centrifugal pumps should be installed with a
flooded suction as near to the liquid source as possible. A MP
CHEMFLO is not a self-priming pump. If the liquid source is
located below the pump a footvalve and some provision for
priming must be used. The pump housing and suction line
must be completely filled with liquid before operation.
Piping should include shutoff valves and pipe unions on both
the discharge and suction to isolate the pump for mainte-
nance.
Provisions for suction and discharge pressure gages are
recommended for troubleshooting. The suction line should
be as short as possible, at least as large as the pump suction
connection, include as few fittings as possible and those
should have a long radius to keep friction losses at a min-
imum. If a footvalve or strainer is included the FREE AREA
should be at least three times the area of the pump suction
connection. The suction piping must be absolutely free of
leaks.
Both suction and discharge piping should be supported in-
dependently of the pump. never draw or pull pipe into place,
this may impose a strain that will result in misalignment be-
tween the pump and driver or otherwise adversely affect the
operation of the pump. After connecting piping to the pump
rotate the shaft several times to check for rubbing or binding.
INSTALLATION FOR CHEMFLO PUMPAKS:
If it is necessary to install the pump above the level of the
liquid, a priming line should be connected directly to the
suction line. A check valve must be used in conjunction with
a priming line or the priming liquid will merely pass through
the suction line to the liquid source. The priming of the suc-
tion line evacuates the air in the suction line and pump. This
series of pumps will not handle air and therefore all air must
be displaced from the suction line and pump before the
pump can operate. Be sure that the pump housing is filled
with liquid before starting the pump.
THE MECHANICAL
SEAL IN THE PUMP MUST NOT BE OPERATED DRY.
Pipe or hose of the same size (or larger) as inlet and outlet
openings should be used on the installation. When using
pipe, avoid sharp bends and use long radius elbows wherev-
er possible. This will keep friction loss at a minimum and al-
low the pump to operate more effectively. Use pipe dope on
all connections and be sure all fittings are airtight, especially
on the suction side of the pump. An air leak on the suction
side of the pump will prevent proper operation. A section of
non-collapsible hose between piping and pump may be used
as a vibration dampener.
BEARING INSTALLATION (PEDESTAL MODELS):
Check the shaft to insure that it rotates freely. Shafts should
be aligned in accordance with the instructions of the cou-
pling manufacturer. Final alignment must be performed after
the pump has been completely installed and the pump and
driver are at operating temperature. Proper shaft alignment is
the responsibility of the installer.
The MP CHEMFLO centrifugal pump should be installed with
a flooded suction as near to the liquid source as possible.
CHEMFLO pumps are not self-priming pumps. If the liquid
source is located below the pump a footvalve and some
provision for priming must be used. The pump housing and
suction line must be fully primed before operation. The me-
chanical seal in the pump must not be operated dry.
Piping should include shutoff valves on both the discharge
and suction to isolate the pump for maintenance. Provisions
for suction and discharge pressure gages are recommended
for trouble shooting. The suction line should be as short as
possible, at least as large as the pump suction connection,
include as few fittings as possible and those should be long
radius to keep friction losses at a minimum. If a footvalve
or strainer is included the free area should be at least three
times the area of the pump suction connection. The suction
piping must be absolutely free of leaks.
Both suction and discharge piping should be supported in-
dependently of the pump. Never use excessive force to move
the pipe into place. This may impose a strain that will result
in misalignment between the pump and driver or otherwise
adversely affect the operation of the pump. After connecting
pipe to the pump rotate the shaft several times to check for
rubbing or binding.
