is connected by a support frame to an end
suction volute casing, fitted with wear ring(s).
The motor, frame, shaft and impeller
assembly can be withdrawn from the volute
for maintenance without disconnection of
pipework.
The discharge branch is normally positioned
vertically opposite the motor mounting feet,
but it can be orientated in any other direction
that the motor flange holes permit. Motors
can be supplied with or without slide rails,
and on smaller pump sizes only, flange
mounted
motors may be specified.
Additional mounting feet are fitted to the
volute casing BUT these are NOT to be
used to support the pump unless the
pump is fitted with a flange-mounted motor.
The shaft is sealed with a standard
mechanical seal.
Nameplate details are shown on the back
cover, full pump specification can be
supplied on a data sheet, if requested.
Note (1) - Head specified is the Duty Head generated
by the pump only.
(2) - Suction pressure must be included when
assessing the Maximum Working Pressure.
For details of the motor supplied, refer to the
manufacturer's instructions in Appendix I.
4. Assembly and Installation
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.
4.1 Initial Inspection for Damage
During transport and storage, accidental
damage to the pump may have occurred.
When the pump is to be installed, or in the
event of a handling accident, carefully check
that the pump has sustained no damage
before installation and commissioning.
4.2 Preparation for Mounting
Before installation, check that the pump
mounting location is suitable for accepting
the pump. Refer to Section 8, for details of
pump installation dimensions or to a certified
General
Arrangement Drawing when
available.
4.3 Pump Preparation
Abrasion and Entrapment
Hazard
Do NOT touch any moving or
rotating parts Guards are provided
to prevent access to these parts, where they
have been removed for maintenance they
MUST be replaced before operating the
equipment.
Remove packaging but leave the flange
covers in place, check that impeller rotates
freely by hand by turning the shaft.
4.4 Pump Installation
Eurostream pumps are designed to be
mounted on rigid foundations, using four
bolts to firmly attach the motor feet or slide
rails to suitable baseplate, framework or
concrete plinth. Only when using flange
mounted motors is the pump to be
mounted using the volute casing feet.
4.5 Suction Pipework
The run of suction pipework must be such
that air can NOT become trapped where it
would be sucked into the pump on starting.
The bore of suction pipe is recommended to
be one or two sizes larger than the pump
suction branch and reducers if used must be
eccentric to eliminate the possibility of an air
pocket being formed.
Unacceptable Suction Pipework
Bends in the suction pipeline should be as
large as possible, the pipe made as short
and as straight as possible and all joints
must be fully airtight. If fitting a foot valve, it
should have a free area of one and a half
times the area of the suction pipe.
Where pumping water at temperatures
above 70°C, care must be taken to ensure
that enough pressure is available at the
impeller entry to prevent vaporisation.
An appropriate fine strainer is recommended
to prevent foreign matter from being drawn
into the pump. A screen or basket strainer
may also be required to hold back larger
items. These should be sized to maintain the
