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.

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.

2.5 Construction Code
This code denes construction material of various components in the pump.
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.
3.5 Heavy Duty Bearing Housing
The pump has positively located dual bearings.
