Introducing PumpEng
Company Prole
PumpEng is an Australian company founded in 2001 that specialises in submersible
pumps for use in mining, construction and industrial dewatering. Founder Paul Meneghel
has experience in submersible pumps and mining stretching back to the 1980s.
PumpEng uses innovative design to manufacture pumps that perform well in the toughest of
circumstances. PumpEng has been successful in the Australian market with its innovative
line of Raptor® pumps. Now PumpEng have launched a new pump - JetGuard®- that uses
patented design innovations to better handle underground mining conditions including
the presence of Shotcrete fibre and other tramp material.
What Does a Broken Pump Really Cost a Mining Operation?
Many dewatering pumps were designed before Shotcrete was
widely used in underground mining. Shotcrete fibres are now
a major cause of underground pump failure and production
delay. In a multi million dollar operation, even small delays can be
expensive.
Benefits of JetGuard® for Mining Operations
PROTECTED - Less Fibre Gets In
A hydraulic curtain repels surface fibre, and the suction strainer intake is on the bottom of
the pump, not the side. So less Shotcrete fibre gets inside. If any fibres do get in, a cutter
plate chops up fibres into tiny pieces.
TOUGHENED - Less Damage Gets Done
Internal components in the wet end are tough metal, not elastomer. Fibre and tramp can
more quickly destroy elastomer components, while toughened steel components power on.
The mechanical seal is in a non pressurised zone, away from the high pressure intake area
and removed from the fluid/Shotcrete path.
PRODUCTIVE - Less Downtime More Production
JetGuard® has been designed for tough environments, to keep on pumping when traditional
dewatering pumps might fail.

Plant & Equipment

The PumpEng manufactured “Raptor”
series of pumps are electro submersible
de-watering pumps.
By incorporating a water cooled, jacketed
motor these pumps can run both fully and
partly submereged.
This feature allows de-watering to be
achieved to a lower level than that which
can be achieved with non jacketed
submersible pump designs.
To further enhance this feature the
“Raptor” pump series are supplied with
class H (180 C) insulated motors thereby
increasing the allowable temperature rise
which would be applicable if a standard
class F(150 C) motor was used.
This feature increases the life expectancy of
the motor when dry run or snore operation
is encountered.
Another design feature which helps
to extend pump life during dry run or
snore operation is the incorporation of dual
mechanical seals running in an oil bath.
The standard motor configuration is 3
phase, 50 cycle. Motor speed is 2 pole
and motors are available in both 415v
and 1000v.
Variations on these standard motor
specifications are available to suit
specific requirements. Note that the
“Raptor” series of pump are not
Ex-approved and as such cannot be used
in explosive or flammable environments.
The design speed of these pumps is set at
2 pole so as to allow high head pumping
to be achieved. All pump Impellers
are of a semi open design with full
rear shrouds to help maintain constant
discharge head over the wear life of the
Impeller.
Thepumpsaredesignedaswearresistant
de-watering pump, incorporating
unique features to minimize both
the effects of wear and the costs
associated with the damage that occurs
through wear. Due to the high speed
and high head design of these pumps
they are not intended for use as a slurry
pump.

Always lift the pump via the lifting handle. Never lift or drag the pump
via electrical power cable.
Always ensure the pump is secured and packaged to prevent damage
during transportation. When transporting along unsealed roads, pack
the pump so as prevent damage which can be caused to the bearings
and seals by excessive vibration.
Do not drop the pump as not only can this cause physical damage to
the exterior of the pump it can also cause damage to bearings and
mechanical seals.
Where pumps are stored for extended periods ensure that the cable,
seal sleeve and mechanical seals, are intact putting the pump into
operation, also ensure that the impeller can rotate freely and that
oil/grease levels are correct.
Installation must be undertaken by suitably qualified persons. Ensure all
relevant safety standards are adhered to and be aware of hazards
which exist in the area in question.
When positioning the pump in an operating environment take measures to
reduce the amount of solids and fines which can enter the pump.
Wear and associated repair costs are directly related to the amount of solids
being pumped.
Ensure that all electrical connections are correct and that suitable overload/motor
protection devices are used and that the pump is operating within its
designated current range.
Ensure the direction of rotation is correct.
Ensure discharge lines and fittings are properly secured and rated for the
installation’s design pressure. All discharge lines must be free of kinks
and blockages.

The Raptor series of pumps are designed for long periods of trouble free operation.
The frequency of service inspections is determined by the operating conditions
which the pump is operating in.
As a minimum the following inspections should be made every six (6) months, however
site maintenance staff should set inspection intervals based on the operating conditions
which the pumps are operating in.
Note that a drop in output capacity or changes in operating current are an indication
that the pump is in need of inspection.
Ensure all in inspection work is performed by suitably qualified and trained
persons.
Inspect the electrical power cable for damage and replace as necessary.
Measure the insulation resistance of the power cable and motor
windings. If the winding resistance is not correct then remove the
cable and measure the resistance of the windings only. If this reading returns
to normal replace the cable. If the reading does not return to normal the pump
should be sent to a PumpEng dealership for repairs.
Visually inspect all external components of the pump and replace any damaged
components.
Ensure that the cooling jacket internal waterways are free of obstruction, flush/clear
as required.
Check that all nuts, bolts and screws are secure. Remove the oil inspection
screws. (Danger this area may be under pressure, take appropriate
precautions) Lay the pump on its side and pour oil into a suitable container,
check the condition of the lower bearing housing oil. If there is any indication of
contaminates in the oil then it is possible that the mechanical seals
or bearing housing o-rings have failed and as such the pump
should be sent to a PumpEng dealership for repairs. If the oil is not
contaminated replace with new oil (quantity required is 2.0 Liters) ensuring
that the inspection screw o-rings are replaced and the inspection screws are
tightened to 20 Nm.
Remove the stator inspection screw. (Danger this area may be under pressure,
take appropriate precautions) lay the pump on its side and check if there is
any water or oil in the stator casing. If evidence of oil or water are present it is

indicative of a mechanical seal o-ring failure and as such it is recommended
that the pump be repaired by PumpEng dealership. If nil water or oil is evident
replace the stator inspection screw o-ring and ensure that the inspection screw
is tightened to 20 Nm.
Remove the junction box cover and inspect for signs of water. (Danger this
area may be under pressure, take appropriate precautions) If evidence of water
exists determine where the water has entered. If the water has entered from the
stator casing the pump should be returned to a PumpEng dealership for repairs.
If on the other hand the water has entered via the lid or power cable then replace
the cable, 0-rings and seal sleeve as necessary. When re-fitting the seal sleeve
ensure that the cable entry clamps are tightened securely on the electric power
cable.
Inspect all wet end components & replace as necessary.

The motor has been correctly
selected to suit the pump, thrust
load from the pump, electrical
supply capacity, and water availability.
The motor should be installed to be
submerged at all times as this will ensure a
long service life.
These motors may overheat if they are run
continuously on full load while not
submerged or whilst running on the snore.
Connection of the motor to an incorrect
supply will void any warranty.
Protection against single phasing is strong-
ly recommended. If the motor fails due to
single phasing the warranty will be void.
Installation of Lighting Arrestors is also
recommended to protect the control panel,
motor cables, and the motor. Any failure
due to lightening will not be covered by
warranty.
Any cable joints must be done properly by
technically competent technicians. They

Reduced voltage starting using Soft
Starters, VVVF drives, Auto transformers,
(or Star-Delta starters if the motor has been
supplied with 6 leads out), can create
additional problems for submersible
motors. Please ensure compliance with the
following points.
Ambient Temperature of the water to be
pumped and ensure that it is less than the
temperature rating of the motor.
The PH of the water is between 6.5 and 8.
Maximum Chlorine content in water is less
than 500 PPM.
Maximum Sulphuric Acid Iron content in
the water is less than 15 PPM.
Maximum Flourine content in the water is
less than 0.8 PPM.
Maximum San content is less than 50 PPM.
The electrical control equipment includes
suitable fast acting current overload

between each start.
It is strongly recommended that the
“Over Current” protection is set to trip at
about 5% higher than the steady state
current recorded when the motor/pump
is commissioned. It is not recommended
that the “Over Current” protection is
set at just above Full Load Nameplate
Current, as in a lot of cases, this will not
protect the motor if the current increas-
es, especially if the motor is not fully
loaded. We believe that the operator
needs to know if the current starts to
increase, so they can determine why.
All temperatures and all 3
phases of voltage and current
and insulation levels should be
recorded throughout the life
of the installation and moni-
tored and reviewed as a form of
preventative maintenance.
After energising the motor for the first
time, ensure that the starting current
drops to below the nameplate current
within 5 seconds, which means that
the motor has run up to full speed.
Check the starting reaction, flow
rate and pressure from the pump is
running in the correct direction of
rotation. Swapping any 2 of the 3
phase supply leads will change the
direction of rotation.
While the motor is running for the first
time check the water for sand. If sand
appears continue to pump until the
water clears. If the motor is switched
off while the pump is still pumping
sand this could accumulate in the
pump and cause it to seize up.
During testing or checking rotation
the number of starts and the time
between starts needs to be controlled.

The output pressure and flow from
the pump should also be monitored
on a regular basis.
The normal running current, and voltage
on all 3 phases need to be recorded
on a regular basis.

The ball bearings have been greased for
life during assembly - there is no need
for additional oil or greasing during the
operating life of the motor and bearings.
The motor cannot be accessed unless it is
removed from the sump, so everything that
