4. START UP & ROUTINE
CHECKS
4.01 START UP
Before starting pump for the first time or
after servicing or maintenance work, check
the following - failure to do so could damage
equipment or cause injury to personnel.
• All pump head and mounting bolts are
tight.
• All pipe connections are secure.
• All guards, safety and protection devices,
are in place and effective.
• Flushing fluid, if required, is flowing - see
Section 2.10.
• All valves are open - NEVER run pump
against a closed valve.
• Pipes and pump head, if heated, are to
normal operating temperature.
• Pump and pipes are clear of welding flash
or other debris.
NEVER use
Hy~Line
or
Ultima
pumps
to flush the system the first time. Flush
the whole system with suitable cleaning
agents before starting the
Hy~Line
or
Ultima
pump, using another more
suitable pump if necessary. Be aware
that heavy or metal debris tends to
collect at the lowest point in the system.
• Pump is correctly lubricated - see
Section 3.
• Motor is wired for correct direction of
rotation - see Figure 9.
When possible, start pump slowly and
increase speed gradually.
• Listen for unexpected noises.
• Check for leaks.
• Check that pump gives desired flow rate
at normal operating speed.
• Do not continue to run pump if fluid is not
flowing; dry running can damage seals -
see Section 2.10.
• Observe pump during first few hours of
operation - check for noises and
excessive heating of pump bearing
housing, i.e. if above 80°C (176°F), unless
pumping hot liquids when 110°C (230°F)
may be reached.
• If operating at high speeds or with hot
liquids, surface temperatures can exceed
50°C (122°F), safety labels may be
required to comply with local safety
regulations.
