Section 1................................................................Introduction and Safety
ISO PRO Centrifugal Pump
5. MANDATORY SAFETY ACTION
DRAIN THE PUMP AND ISOLATE PIPEWORK BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken where the pumped liquids are hazardous.
NEVER DO MAINTENANCE WORK WHEN THE UNIT IS CONNECTED TO POWER
ENSURE CORRECT LUBRICATION
HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids care must be taken to avoid exposure to the liquid
by appropriate setting of the pump, limiting personnel access and by operator training. If the
liquid is ammable and/or explosive, strict safety procedures must be applied.
Gland packing must not be used when pumping hazardous liquids.
START THE PUMP WITH OUTLET VALVE PARTLY OPENED
This is recommended to minimise the risk of overloading and damaging the pump and motor at
full or zero ow. The pump outlet control valve may need to be adjusted to comply with the duty
following the run-up process. (See section 5, Commissioning start-up, operation and shutdown.)
NEVER RUN THE PUMP DRY
INLET VALVES TO BE FULLY OPEN WHEN PUMP IS RUNNING
Running the pump at zero ow or below the recommended minimum ow continuously will cause
damage to the pump itself and to the seal. Restriction of suction may cause cavitation resulting in
damage to the pump.
PREVENT EXCESSIVE EXTERNAL PIPE LOAD
Do not use pump as a support for piping. Pipe supports and expansion couplings recommended.
DO NOT RUN THE PUMP AT ABNORMALLY HIGH OR LOW FLOW RATES
Operating at a ow rate higher than normal or at a ow rate with no back pressure on the pump
may overload the motor and cause cavitation. Low ow rates may cause a reduction in pump/
bearing life, overheating of the pump, instability and cavitation/ vibration.
HANDLING COMPONENTS
Many precision parts have sharp corners and the wearing of appropriate safety gloves and
equipment is required when handling these components. To lift heavy pieces above 25 kg (55 Ib)
use a crane appropriate for the mass and in accordance with current local regulations.
GUARDS MUST NOT BE REMOVED WHILE THE PUMP IS OPERATIONAL
The unit must not be operated unless coupling guard is in place. Failure to observe this warning
could result in injury to operating personnel.
THERMAL SHOCK
Rapid changes in the temperature of the liquid within the pump can cause thermal shock, which
can result in damage or breakage of components and should be avoided.
DO NOT APPLY HEAT TO REMOVE IMPELLER
Trapped lubricant or vapor could cause an explosion.

Section 1................................................................Introduction and Safety
ISO PRO Centrifugal Pump
6. SAFE NOISE LEVEL
ISO PRO pump noise level is dependent on a number of factors – the type of driver used, the
operating conditions, pipe-work design and acoustic characteristics of the building. The below table is
a guide to calculating the noise level for a pump unit with any given driver.
Approximate Noise Level Table
Driver Sound Level dB(A) Correction For Unit - Add to motor noise level dB(A)
60 - 64 12.0
65 - 69 10.0
70 - 74 8.0
75 - 79 6.5
80 - 84 5.0
85 - 89 4.0
If pump unit noise level exceeds 85 dBA attention must be given to prevailing Health and Safety
Legislation, to limit the exposure of plant operating personnel to the noise. The usual approach is
to control exposure time to the noise or to enclose the machine to reduce emitted sound. You may
have already specied a limiting noise level when the equipment was ordered, however if no noise
requirements were dened then machines above a certain power level will exceed 85 dBA. In such
situations consideration must be given to the tting of an acoustic enclosure to meet local regulations.
7. LEAKAGE PREVENTION
The pump must only be used to handle liquids for which it has been approved to have the correct
corrosion resistance. Avoid entrapment of liquid in the pump and associated piping due to closing of
suction and discharge valves, which could cause dangerous excessive pressures to occur if there is
heat input to the liquid. This can occur if the pump is stationary or running.
Bursting of liquid containing parts due to freezing must be avoided by draining or protecting the pump
and ancillary systems.
8. SAFETY NOTE
a. Read the instruction manual before installation, operation and maintenance of the equipment.
Check and conrm that the manual is relevant copy by comparing pump type on the nameplate and
with that on the manual.
b. The products supplied by Pentair Southern Cross have been designed with safety in mind. Where
hazards cannot be eliminated, the risk has been minimized by the use of guards and other design
features. Some hazards cannot be guarded against and the instructions below must be complied
with for safe operation. These instructions cannot cover all circumstances; You are responsible for
using safe working practices at all times.
c. Pentair Southern Cross products are designed for installation in designated areas, which are to
be kept clean and free of obstructions that may restrict safe access to the controls and maintenance

access points. A Pump Duty Nameplate is tted to each unit and must not be removed. Loss of
this plate could make identication impossible. This in turn could affect safety and cause difculty in
obtaining spare parts.
d. Access to the equipment should be restricted to the personnel responsible for installation, operation
and maintenance of pump unit, adequately qualied and supplied with appropriate tools for their
respective tasks.
e. Pentair Southern Cross requires that, all personnel that are responsible for installation, operation or
maintenance of the equipment, have access to and study the product instruction manual before
any work is done and that they will comply with all local and industry based safety instructions and
regulations.
f. Hearing protection should be worn where the specied equipment noise level exceeds locally
dened safe levels. Safety glasses or goggles should be worn when working with pressurised
systems and hazardous substances. Other personnel protection equipment must be worn where
local rules apply.
g. Do not wear loose clothing or jewelry which could catch on the controls or become trapped in the
equipment.
h. Note the ‘Limits of product application – permissible use’ specied in the manual.
i. Operation of the equipment beyond these limits will increase the risk from hazards noted below and
may lead to premature and hazardous pump failure.
j. Clear and easy access to all controls, gauges and dials etc., must be maintained at all times.
Hazardous or ammable materials must not be stored in pump rooms unless safe areas or racking
and suitable containers have been provided.
k. Improper Installation, Operation or Maintenance of this Pentair Southern Cross Product could result
in Injury or Death.

3. DESIGN OF MAJOR PARTS
3.1 Pump Casing (All Pump Types)
The Casing type is Foot Mounted, ISO vertical, Centerline, End Suction, Top Discharge, one piece
solid construction. A wear ring may be mounted in the casing to provide a close running clearance with
the impeller Neck ring.
3.2 Impeller (All Models)
The impeller is a single suction, radial / Mixed ow, closed design. The impeller is dynamically
balanced, keyed to the shaft. Renewable Neck rings can be press t onto the impeller hubs (front and
back) where needed. Double curvature impeller blades, provide highly efcient suction performance,
higher speed capabilities and greater performance for reduced running costs and maintenance.
Impeller is taper mounted and keyed to shaft and secured by Lock Washer and Impeller nut for
positive locking.
3.3 Lock Washer (All Pump Types)
Lock washers are assembled between impeller and impeller nut. These Lock washers are
manufactured by Nord-Lock. NORD-LOCK is a pair of washers with a wedge-locking action meeting
DIN 25201 which is a unique method using tension instead of friction. The NORD-LOCK bolt securing
system uses geometry to safely lock impeller onto the pump shaft.
3.4 Shaft (All Pump types)
The shaft is made of high grade stainless steel. It is precision machined over its entire length and has
generous llet radii at each change of section to reduce stress concentrations. Water slinger prevents
intrusion of pumped uid into shaft bearing.

1. SAFETY INSTRUCTIONS FOR ASSEMBLY & INSTALLATION
• Do not place ngers 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.
• 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.
• Failure to support suction and delivery pipe work may result in distortion of the pump casing, with the
possibility of early pump failure.
2. LOCATION
• Install the unit close to the source of the liquid to be pumped.
• When selecting the location, be sure to allow adequate space for operation as well as for
maintenance operations involving dismantling and inspections of parts.
• Head room is an important consideration as an overhead lift of some type is required.
3. PART ASSEMBLIES
It is the responsibility of the installer to ensure that the motor is assembled to the pump and lined up.
4. FOUNDATION
The foundation should be level and sufciently rigid and substantial to prevent any pump vibration
and to permanently support the baseplate at all points. The most satisfactory foundations are made of
reinforced concrete. These should be poured well in advance of the installation to allow sufcient time
for drying and curing.
CHECK ALIGNMENT
Prior to grouting, an initial alignment check in accordance with the alignment section
of this document shall be performed to verify that coupling spacing and nal alignment
can be achieved without modifying the hold down bolts or the machine feet. This is
necessary to ensure that the baseplate was not damaged during the transportation.
PUMP INSTALLATION AND FOUNDATION
There are many methods of installing pump units to their foundations. The correct
method depends on the size of the pump unit, its location and noise vibration
limitations. Non-compliance with the provision of correct foundation and installation
may lead to failure of the pump and, as such, would be outside the terms of the
warranty.

5. INITIAL ALIGNMENT
Shaft alignment must be checked again after the nal positioning of the pump unit and connection to
pipe work, as this may have disturbed the pump or motor mounting positions. If hot liquids (above 80
Deg C) are being pumped, alignment should be checked and reset with the pump and motor at their
normal operating temperature.
5.1 Alignment Methods
Correct alignment is essential for the smooth operation of the pump. There are two types of
misalignment between the pump shaft and the drive shaft, which are:
Angular misalignment - Shaft with axis
concentric, but not parallel
Parallel misalignment - Shaft axis parallel, but
not concentric
This misalignment is checked by using a straight edge or any other device as shown in gure given
below. A spacer type exible coupling is used to connect pump shaft to the driver. By using spacer
type of coupling, the complete rotating unit can be removed from the volute without removing pump
casing or rotor and without disconnecting piping connections. However other types of coupling can be
supplied on request.
Ensure pump and driver are isolated electrically and the half couplings are
disconnected
Align the motor to the pump, not the pump to the motor
PUMP ALIGNMENT AND THERMAL EXPANSION
The pump and motor will normally have to be aligned at ambient temperature and
should be corrected to allow for thermal expansion at operating temperature.
Adjustment to correct the alignment in one direction may alter the alignment in another
direction. Always check in all directions after making any adjustment.
ALWAYS REMEMBER “A FLEXIBLE COUPLING IS NOT A UNIVERSAL JOINT”

Section 5....................................................................................Installation
ISO PRO Centrifugal Pump
The alignment is achieved by adding or removing shims under the motor feet and also moving the
motor horizontally as required. In some cases where the alignment cannot be achieved it will be
necessary to move the pump before recommencing the above procedure.
5.2 Shims
The shims between the equipment feet and mounting surface should be clean and dry. This is
especially critical for pumps in service for some time and need to be realigned. Water, dirt and rust
may change the height of the shim pack over a period of time. Shims should be made large enough
to support the weight of the equipment on its mounting foot. Do not use many thin shims as this may
result in a spongy mounting. Move the equipment vertically by adding or removing the calculated
thickness of shims.
6. ASSEMBLE COUPLING
a) Assemble coupling as per the manufacturer’s instructions.
b) Install coupling guard
7. PIPING
7.1 Piping Good Practice
a) In order to minimise friction losses and hydraulic noise in the pipework it is a good practice to
choose pipework that is one or two sizes larger than the pump suction and discharge.
b) Typically main pipework velocities should not exceed 2 m/s suction and 3 m/s on the discharge.
7.2 Suction Piping
a) The inlet pipe should be one or two sizes larger than the pump inlet bore and pipe bends should be
as large radius as possible.
b) Double bends must be avoided in suction line and a straight run of pipe, equal to 8 or 10 times the
