1)
A packed pump can be run with grease, an external flush, or nothing at all.
If grease is used, it should be compatible with the fluid being pumped (i.e. non-
soluble and non-reactive). Inject grease into the fitting after removing the drain plug
on the opposite side. This greasing should be repeated periodically. If nothing is
used, there must be some leakage out of the pump so the packing is well lubricated.
NOTE:
2)
Don't over tighten the packing screws. You will burn the packing and
damage the shaft. Packed boxes should leak at a rate of 8 to 10 drops per minute.
Tighten the gland screws 1/4 turn at a time to allow the leakage rate to stabilize.
Repeat until a rate of 8-10 drops per minute is stable.
ATTENTION
B)
If the pump is equipped with a double mechanical seal, a lubrication loop to
pressurize the seal chamber is required. The seal chamber should be kept at
approximately 5 to 20 psi (.3 to 1.4 bar) higher than the discharge pressure. In
addition, the flow rate through the seal chamber should be approximately 1/8 GPM,
for fluids with specific heat values other then 1.0 (i.e. water) the flow rate should be
adjusted.
!
ATTENTION
When the pump is handling flammable, toxic or hazardous fluid, flush the
pump prior to removal from the piping system. Prior to flushing and disassembly
consult the Material Safety Data Sheet (MSDS) for the pumped fluid to ensure
procedures and precautions as specified are adhered to. Exercise extreme care to
avoid contact with the fluid.
ATTENTION
The pump has internal bearings and wear plates, which require replacement over
time.
ATTENTION
Replace drain plug after greasing.
Do not wear loose clothing around rotating objects.
Insure coupling guard is replaced prior to starting.
REMOVAL FROM SYSTEM
Insure that the motor is locked out.
MAINTENANCE AND REPAIR
Insure the pump's motor switch is in the "off" position and locked
out.
