When readying the pump for service, determine whether the lubricant in the pump is suitable for introduction
into the process. Additional information on ISO 32 or PL-2 can be found at
contacting Imo Pump.
WARNING
It is important the lubricant does not leave carbon residue when heated and evaporated.
All organic oils and many synthetic oils will leave carbon residue when evaporation occurs.
Carbon residue has the appearance of a baked-on, enamel finish, and has the same effect as if
a strong adhesive was introduced into the pump.
Drain the excess fluid from the Imo Pump, and flush the lubricant if there are concerns about
contamination of the process line, or if there are concerns about use of the lubricant at operating
temperature. After flushing, the pump must be lubricated internally. Pour a process-compatible,
temperature-compatible lubricant into the inlet port and turn the pump drive shaft by hand until the
lubricant flows from the discharge port.
E.3.2 Preheating, Cooling
WARNING
o
Do not allow the pump to change temperature rapidly.
o
Do not apply open flame to a pump.
o
Do not allow leaking fluid to catch fire.
o
Do not expose the pump to liquid nitrogen or other extremely cold substances.
o
Do not attempt to quench a hot pump by applying water or other cool liquid to the surface.
If the pump is to be preheated or cooled prior to installation, heat or cool the pump to the operating
temperature by use of an approved method, such as a band heater, bar heater, oven, cooling or
environmental chamber, liquid bath or heating jacket, which can fully reach the operating temperature of the
pumping system. Monitor the pump temperature and ensure the target temperature has been met and
maintained. Allow ample time to heat-soak the pump thoroughly and evenly (including the seal
arrangement).
E.3.3 Mounting / Alignment / Installation
Mounting, alignment and installation of the pump should only be performed by trained, specialized
personnel in conjunction with the appropriate Original Installation, Care and Maintenance Instructions.
E.3.4 Start-up
Consult the Installation, General Maintenance and Troubleshooting Manual (SRM00101) for full start-up
instructions.
WARNING
If operating temperatures exceed 60°C (140°F), measures must be taken to avoid skin contact.
Flush out the plumbing system before connecting the pump.
Fluid entering the pump should be filtered to limit particle size to ½ the rotor clearances in the pump
during operation. Consult the factory.
Rotate the pump drive shaft by hand after mounting and fully tightening the mounting bolts. The
shaft should turn easily.
Make sure fluid freely enters the pump before starting. Be sure to apply sufficient positive inlet
pressure to prevent cavitation during operation. Be sure inlet valves are open.
