32 6EM Thru 18GM - 1100 Vertical Turbine Pumps
SECTION 4 OPERATION
General
Because variations may exist in both the
equipment and in the particular installation
of the a pump and driver, specific operating
instructions are not within the scope of this
manual. However, there are general rules
and practices that apply to all pump
installations and operation.
CAUTION
Before starting or operating the pump, read
this entire manual, especially the following
instructions.
Before starting the pump:
1. Rotate the unit or assembly by hand to
assure all on moving parts are free.
2. Install coupling guards around all
exposed rotating parts. Guards are
mandatory on discharge head (motor
pedestal) openings if the pump is
equipped with an adjustable coupling.
3. Install packing (or mechanical seal).
4. Install water line to packing box (for
mechanical seals).
5. Observe all DANGER, WARNING and
CAUTION tags attached to this
equipment.
6. Ensure water in sump is at the specified
level for adequate submergence.
7. If pump has a packed box, adjust the
packing gland finger tight. Refer to
Packing Adjustment in the maintenance
section to properly adjust packing.
If excessive vibration or noise occurs during
operation, shut the pump down and review
the Trouble Shooting section. If the problem
cannot be corrected, consult a Layne/Verti-
Line representative.
Operating at Reduced Capacity
In a typical application covering a wide
range of flow rates a variable speed driver is
often used to adjust pump and this is taken
into consideration by Layne/Verti-Line when
selecting the pump and impeller trim.
Although these pumps are applicable over a
wide range of operating conditions, care
should be exercised when doing so when
the actual conditions differ from the sold
conditions. You should always contact your
nearest Layne/Verti-Line distributor or
factory before operating the pumps at any
condition other than that for which they were
sold.
Generally, these pumps can be operated
continuously at capacity equal to 60% of the
pump capacity at the best efficiency point,
and at higher capacities.
Initial Startup
Inspect the complete installation to ensure
that the installation instructions of this
manual, and the manuals of all the related
equipment, have been followed and that the
installation is complete.
Ensure that the driver is properly serviced,
and that the proper pump rotation is
obtained.
Rotate the pump shaft by hand. It should
rotate freely on motor driven installations.
Ensure the discharge valve is open.
Start the pump according to the following
procedure:
1. Start the driver according to the driver
manufacturer's instructions.
2. Immediately after the pump has been
started, check lubrication system,
stuffing box lubrication and operation,
and pump noise level. Continue to
monitor these for the first several hours
of operation.
