3. GENERAL DESCRIPTION
SPP Pumps’ AUTOPRIME XF Pumps are a
range of horizontal centrifugal pumps. The
two or three vane open impeller design will
handle dirty water, industrial effluents, and
sludge etc, including solids.
The mechanical assembly comprises a rigid
shaft, supported by oil lubricated bearings
with an open vane type impeller mounted in
a removable bearing housing assembly.
The bearing housing is air cooled by a fan
mounted on the shaft.
This is attached to an end suction volute
casing fitted with a front wear plate. The
bearing housing, shaft and impeller
assembly can be withdrawn from the volute
for maintenance without disconnection of
pipework or the driver provided that a
spacer coupling has been fitted.

XF300 & XF400 Range Centrifugal Pumps
Operators Instructions for
The discharge branch is positioned at 45°
above the centre of the pump volute. This
allows the fitting of a ball or flap type nonreturn valve to give a horizontal discharge.
The pump is centreline mounted and the
volute is provided with an access point for
examination of the impeller.
The pump has been designed for use with
an automatic priming system typically one
using a vacuum pump with a priming tank.
As several varieties of priming system may
be fitted, the details and operation
instructions for the particular priming
system used are fully described in a
separate priming system manual.
Reference to priming functions in this
manual apply to all priming systems in
general.
The complete assembly is of a rigid
construction, being intended for mounting
on suitable baseplate with electric motor or
diesel engine driver. A suitable coupling is
required to transmit the rotational drive
between pump and driver.
The shaft is sealed by an oil cooled and
lubricated mechanical seal. Alternative
seals can be supplied by arrangement to
suit special customer requirements and the
liquid being pumped.
The materials of construction are:
Component Material
Impeller Stainless Steel
Volute Casing Cast Iron
Suction Cover SG Cast Iron
Backplate SG Cast iron
Bearing Housing Cast Iron
Shaft Stainless Steel
Nameplate details are shown on the back
cover of this manual, full pump specification
can be supplied on a data sheet, if
requested.
4. ASSEMBLY & 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.
Abrasion & 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.
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 no damage has been sustained
by the pump before installation &
commissioning.
4.2 Preparation for Mounting
Before installation, check that the pump
mounting location is suitable for accepting
the pump unit. Refer to Section 8, for
details of pump installation dimensions or to
a certified General Arrangement Drawing,
when available.
4.3 Pump Preparation
Remove packaging but leave the flange
covers in place, check that the impeller
rotates freely by hand by turning the shaft.
ATTENTION
The bearing housing requires cooling by a
fan fitted on the shaft. This fan is supplied
loose with each pump and must be fitted to
the shaft before assembly of the shaft
coupling.
Abrasion & Entrapment Hazard
The cooling fan MUST be guarded.
Installers of pumps must provide and fit a
suitable guard, this may be integral with the
coupling guard provided that an average air
velocity of 5m/sec at 2000rpm is achieved.
ATTENTION
Care must be taken to ensure that the air
entering the fan does not exceed 40 deg C.
Further details of suitable arrangements are
available SPP Pumps Limited.

XF300 & XF400 Range Centrifugal Pumps
4.4 Pump Installation
It is recommended that the pump unit is
fitted to the baseplate before fitting the
motor and coupling. The distance between
shaft ends should be established to suit the
coupling by reference to the manufacturer's
instructions.
4.5 Shaft Alignment
To minimise the side load on the bearings
and to achieve full coupling and bearing life,
it is recommended that the shafts are
aligned as accurately as possible i.e. well
below the allowable misalignment of the
coupling. Refer to the coupling
manufacturer's instructions or proceed
generally thus:
a) Lateral Alignment
Mount a dial gauge
on the motor shaft
or coupling with the
gauge running on
the outer machined
diameter of the
pump coupling. Turn the motor shaft and
note the total indicator reading.
b) Angular Alignment
Mount a dial gauge
on the motor shaft
or coupling to run
on a face of the
pump coupling as
near the outside
diameter as
possible. Turn the
motor shaft and note the total indicator
reading.
c) Confirm Lateral Alignment
Mount the dial
gauge on the pump
shaft or coupling
with the gauge
running on the
outer, machined
diameter of the
motor coupling.
Turn the pump shaft and note the total
indicator reading.
d) Adjustment
The motor must be shimmed and repositioned to align the shafts within the
coupling manufacturer's specifications.
e) Alternative Method
Our policy is one of continuous improvement and we reserve the right to alter specifications at any time
Operators Instructions for
If a dial gauge is not available, callipers or
taper gauge may be used to measure the
distance between the coupling flanges at
four points around the circumference and a
straight edge used to check the lateral
alignment of the outer flange diameters.
ATTENTION
Shaft alignment must be checked again
after the final positioning of the pump unit
and connection to pipework as this may
have disturbed the pump or motor mounting
positions.
4.6 Suction Pipework
It is recommended that the pump is
installed as near to the liquid source as
possible
Any rigid pipework should be supported
independently and close to the pump so
that no strain is transmitted to the pump
when the flange bolts are tightened. Use
pipe supports at intervals necessary to
provide support. When expansion joints are
used in the piping system, they must be
installed beyond the piping supports closest
to the pump.
ATTENTION
Collapsible hoses must not be used on
the suction side of the pump.
Install piping as straight as possible,
avoiding unnecessary bends. Where
necessary use long sweep 90° bends or
fittings to decrease friction losses.
Make sure that all suction piping joints are
air tight. Provide pipe expansions when hot
fluids are to be pumped. Where reducers
are used, eccentric reducers (tapered side
down) are to be fitted in horizontal suction
lines and straight taper reducers in vertical
discharge lines. Undulations in the pipe
runs or misuse of reducers may cause the
formation of air pockets in the pipe and thus
prevent the efficient operation of the pump.
The suction (and discharge) pipes can be
one or two sizes larger than the pump
flange connections. A horizontal suction line
should have a gradual rise to the pump.
A correctly sized filter or strainer must be
fitted to hold back larger items.
The suction pipe work should be flushed
