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.

a. When the pump is power on, if floating switch (or water-level detector) is “ON”, it
means the pump starts to work.
b. In the running of the pump, if floating switch (or water-level detector) is “OFF”. it
means the pumps will stop working after 60s continuous working, but if floating switch
(or water-level detector) is “ON” again in 60s after “OFF”, the pump will be non-stop.
c. Stop time: After the pump stops for low water-level, it will not start within 60s even
if floating switch (or water-level detector) is ON; unless plug in the power again after
power off.
d. Recovery mode: The pump stops for low water-level, it will start automatically after
60s when floating switch (or water-detector) is ON.
NOTE:
CTS Metal head of electrode will be ON when touching the water, OFF when
leaving water.

Installation
The pump is transportable and intended to operate either completely or partially submerged
in the pumped liquid. The pump is equipped with a connection for hose or pipe.
1.)
2.)
Run the cable so that it has no
sharp bends, is not pinched,
and cannot be sucked into the
pump inlet.
a. Soft pipe installation:
Push the hose all the way to
the base of the hose coupling.
Tighten the hose clamp to
secure the hose in place.
Handle the pump carefully. When suspending the pump to raise or to lower it, attach a
wire rope or a chain to the pump’s handle.
b. Hard pipe installation:
Align the pipe and pump outlet and keep vertical, then screw in clockwise.

7.) The pump must be placed upright during operation. If there is a risk that the pump could
be buried under the sediment, place the pump on a base made up of materials such as
concrete blocks.
5.) The discharge hose can be run vertically or horizontally, but must be without sharp bends.
possible length of discharge hose and minimize the number of bends. Verify that the end
of the hose (discharge side) is lifted above the water surface. If the end of the hose is
submerged in water, it may cause the water to flow back when the pump has been
stopped. If the end of the hose is located at a level that is lower than that of the source
water surface, water may continue to flow out even after the pump has been stopped.
Installation
NOTE:
Appropriate piping materials must be provided by the user. Piping materials are not included
with the product.

CAUTION:
If an excessive amount of sediment is drawn into the pump, it may cause the pump to
wear, which can lead to current leakage or electrical shock.

General Precautions
Requirements
Grounding
ELECTRICAL HAZARD:
• A certified electrician must supervise all electrical work. Comply with all local codes
and regulations.
• Before starting work on the unit, make sure that the unit and the control panel are
isolated from the power supply and can not be energized. This applies to the control
circuit as well.
• Leakage into the electrical parts can cause damaged equipment or a blown fuse.
• Make sure that all unused conductors are insulated.
• There is a risk of electrical shock or explosion if the electrical connections are not
correctly carried out or if there is fault or damage on the product.
ELECTRICAL WARNING:
Do not megger test CT/CTS pump as these pumps are equipped with electronic smarts
and these can be damaged using an electrical megger tester.
WARNING:
Do not install the starter equipment in an explosive zone unless it is explosion proof rated.
ELECTRICAL HAZARD:
• You must ground all electrical equipment. This applies to the pump equipment, the driver,
and any monitoring equipment. Test the ground lead to verify that it is connected correctly.
• If the motor cable is jerked loose by mistake, the ground conductor should be the last
conductor to come loose from its terminal. Make sure that the ground conductor is longer
than the phase conductors. This applies to both ends of the motor cable.
• Risk of electrical shock or burn. You must connect an additional ground fault protection
device to the grounded connectors if persons are likely to come into physical contact with
the pump or pumped liquids.
WARNING:
To prevent damaging the pump and causing current leakage, which may lead to electrical
shock, be sure to install the ground wire securely.
CAUTION:
To prevent electrical shock caused by improper grounding, do not connect the ground wire to
a gas pipe, water pipe, lightning rod, or telephone ground wire.
These general requirements apply for electrical installation:
•
•
•
•
The mains voltage and frequency must agree with the specifications on the data plate.
The fuses and circuit breakers must have the proper rating, and the pump overload
protection (motor protection breaker) must be connected and set to the rated current
according to the data plate and if applicable the cable chart. The starting current in
direct-on-line start can be up to six times higher than the rated current.
The fuse rating and the cables must be in accordance with the local rules and regulations.
If intermittent operation is prescribed, then the pump must be provided with monitoring
equipment supporting such operation.
