The use of suitable forklift truck and four-chain
crane sling equipment is recommended but
locally approved equipment of suitable rating
maybe used.
Pumps are usually supplied on pallets for
handling by forklift truck, to lift from the pallet
the pump should be slung as shown.
Pump weight is shown on the general
arrangement drawing supplied with each
pump or pumpset.
2.3
Storage
Shearing Hazard
Do NOT place fingers or hands etc. into
the suction or discharge pipe outlets and
do NOT touch the impeller. If rotated this
may cause severe injury. To prevent ingress
of any objects, retain the protection covers or
packaging in place until removal is necessary
for installation. If the packaging or suction and
discharge covers are removed for inspection
purposes, replace afterwards to protect the
pump and maintain safety.
2.3.1 Temporary Storage for up to Six Weeks
If the pump is not to be used immediately, it
should be stored carefully in a horizontal
position, in a sheltered, dry location. Additional
rust preventative should be applied to all
unpainted carbon steel or cast iron parts. Fit
or retain in place the covers to the suction and
discharge
flanges and all other pipe
connections. Rust preventative and flange
covers should not be removed until final
installation.
When pumps are not in use, the pump shaft
should be rotated several turns, every six
weeks.
2.3.2 Long Term Storage
It is recommended that the pump is stored in a
clean dry place that is not subject to a wide
temperature variation. Pack the bearings with
the specified grease and periodically inspect
the bearing housings to ensure that they are
free from damp and moisture. Leave the
covers for the suction and discharge flanges in
place or replace with suitable covers to
prevent ingress of dirt or moisture. Rotate the
shaft several turns monthly, to distribute the
grease and prevent pitting of bearing surfaces.
If storage in the open cannot be avoided,
cover the pump with a tarpaulin sheet, but
allow dry air to circulate around the pump.
For special protection of electric motors and
mechanical seals, refer to the manufacturer’s
instructions in Appendix l & III.
2.3.3 Exposed or Extreme Conditions Storage
For exposed storage or extreme variants in
atmospheric or environmental conditions,
please refer to SPP Pumps Ltd.
3. General Description
SPP Pumps Ltd. Thrustream Pumps are a
range of centrifugal pumps that are usually
supplied as pumpsets with electric motors but
can be supplied separately for customers to fit
to drivers of their own preference.
3.1. Pumps
The mechanical assembly comprises a rigid
shaft, supported by grease-lubricated ball
bearings. The pump casing is fitted with wear
rings and normally contains a double entry
shrouded type impeller mounted on a stiff
shaft. Single side entry impellers are used for
two pumps in the range. The seal chamber is
housed in the casing inserts and these are
retained within the casing. Some impellers
may be fitted with wear rings if required.
When the top half casing is removed, the
bearing housings, inserts, shaft and impeller
assembly can be removed from the bottom
casing for maintenance without disconnection
of pipework.
The suction and discharge branch flanges are
positioned horizontally at 90 degrees to and
below the shaft centreline. The pump casings
allow for construction to suit different rotations.
