Where applicable, if a separate supply for
the pump seal is to be used, connect the
feed pipes.
4.3 Waste and Drain Lines
Waste water lines should be run from all
ancillary connections such as gland drains
or tundish etc. Where applicable, these are
shown on the General Arrangement
Drawing provided.
When installed under positive suction head
conditions, pumps should be provided with
an air release valve on the top of the pump
casing to provide a means of exhausting
trapped air.

Check List Completed

Date
If SPP Pumps Limited Service Department
is contracted to carry out the initial test run,
the check-list shows items to be completed
before the engineer arrives. It is SPP
Pumps Limited policy that service engineers
will give as much assistance as possible to
the customer in solving site problems.
However, if due to incomplete installation or
failure of equipment not supplied by SPP
Pumps Limited, further visits are required to
complete commissioning then, additional
charge will be made.
5.2
Initial Test Run
It is recommended that the initial test run is
done
by
an
SPP
Pumps
Limited
commissioning engineer.
ATTENTION
Refer to the pump
instruction manual for instructions for
commissioning pumpsets.
6 Grouting
After successful testing, grouting is required
to compensate for uneven foundations,
distribute the weight of the pumpset,
prevent movement and reduce vibration.
Use only an approved high-strength grout,
prepared and poured in accordance with the
manufacturer's instructions.
Build any formwork required to contain the
grout. If an epoxy grout is to be utilised
then the foundation surface should remain
dry. For other types of grout, soak the top
of the concrete foundation thoroughly with
water until absorption stops then, remove
any excess.
Fit temporary formwork (shuttering) to the
preferred height around the baseplate to
prevent grout running out when poured. Fill
the space inside the baseframe level with
top of the channels or to the level of the top
plate with grout ensuring that there are no
air pockets. DO NOT use vibration
techniques to aid this procedure. Dress
to a smooth finish and allow the grout to
harden.
After the grout has thoroughly hardened
remove the temporary shuttering, check the
foundation bolts and re-tighten if necessary.
Re-check the shaft alignment and adjust
if necessary. The pump is now ready for
normal use.
Approximately 14 days after the grout has
been poured or when it has thoroughly
dried, apply an oil based paint to the
exposed faces of the grout to prevent air
and moisture from coming into contact.
