The standard pump is fitted with a soft packed
seal, internal component mechanical seals
and external cartridge mechanical seals are
available as an option. These pumps are
normally supplied with a cast iron casing and
impeller but bronze may be supplied where
required. Other parts may be supplied in a
variety of materials to suit the pump
application.
In standard form, these pumps are designed
to pump liquids at temperatures up to 80
o
C.
Where pumps are needed to suit higher
temperatures, please refer to SPP Pumps Ltd.
Nameplate details are shown on the back
cover of this manual, full pump specification
can be supplied on a data sheet, if requested.
Note 1) The head specified is the Duty Head
generated by the pump only.
2) - Suction pressure must be included
when assessing the Maximum Working
Pressure.
3.2 Electric Motor Driven Pumpsets
Pumpsets are supplied mounted on a
substantial fabricated baseplate, the complete
assembly is of a rigid construction, being
intended for mounting on suitable foundations.
These pumpsets are supplied fitted with a
proprietary high efficiency electric motor
adequately sized for the duty specified. For
details of the motor supplied, refer to the
manufacturer’s instructions in Appendix I.
The proprietary flexible coupling has been
selected to meet the power transmission and
other operating requirements for the pumpset.
Coupling fitting and maintenance details are
given in the manufacturer’s instructions in
Appendix II.
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 is not damaged 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 the certified General Assembly
drawing, for details of pump installation
dimensions.
4.3
Location of Pump
The pump should be located as near the liquid
source as practical, with adequate accessibility
for inspection and repair and sufficient
headroom for lifting tackle if necessary.
Where pumps are electric motor driven, power
source electrical characteristics should match
those shown on motor data plate. A qualified
electrical contractor should be used to make
the electrical connection.
4.4 Foundations
The pump is to be mounted on a substantial
floor or plinth and secured with suitable
foundation bolts to minimise vibration. The
foundation must have a flat level surface and
be of sufficient depth to contain the foundation
bolts. The pump unit should be installed with
the flange faces set in a vertical position.
Packers may be placed under the baseplate
near the bolt holes to level the unit if the floor
is uneven. The foundation bolts should be
tightened and the shaft alignment checked
again before commissioning and putting the
pump into operation.
For full installation instructions and guidance
on the design of suitable foundations for
pumpsets refer to the SPP Guide to Pump
Installation, obtainable on request from SPP
Pumps Ltd.
4.5 Pump Preparation
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.
For soft packed pumps the packing rings and
related components are often supplied loose.
Ensure that the packing is installed as per
instructions in section 6.2 paragraphs 10 to
20.
Remove packaging but leave the flange
covers in place, check that impeller rotates
