If you are not sure if the hydraulic power
source being used to drive this pump is
properly sized or connected, call Sterling
Fluid Systems Limited.
The power unit should be located as near to
the pump location as possible. The
maximum length of hydraulic hose that may
be used without a significant reduction in
pump performance is 40m. However, by
increasing the hose diameter, performance
can be restored. Consult Sterling Fluid
Systems for more details.
The power unit is usually driven by a diesel
engine that may be mounted inside a noise-
reducing canopy for use in noise sensitive
areas to comply with local noise regulations.
The fuel tank should be sized to give
extended running time. The running time
will depend upon the pumping load.
The power unit should be provided with
automatic shutdown to prevent damage in
the event of low levels of engine or
hydraulic oil and high engine or hydraulic oil
temperature.
The speed of the engine should be
adjustable to suit the load on the pump,
reducing the speed for reduced demand will
increase fuel efficiency and reduce wear.
To minimise the potential harmful effects on
the environment in the event of an oil leak
or
spillage, Sterling Fluid Systems
recommend the use of Biodegradable
Hydraulic 46 Oil.
However, the pump will
run satisfactorily on good quality hydraulic
oils of viscosity below 150SSU @ 38°C
(100°F) or equivalent specification.
Note: When using vegetable (Rape Seed) based
biodegradable oil it is important to check
the condition of the oil frequently as it tends
to breakdown more quickly than the more
expensive
mineral or synthetic
biodegradable oils.
NOTE – DO NOT MIX OILS
To minimise wear and maintain pump
performance, the hydraulic oil must be
replaced regularly and the hydraulic circuit
must be fitted with a 10micron filter.
1.2 Hydraulic Hoses
The hydraulic hoses supplied for use with
this equipment are designed to prevent
incorrect connection, but if non-approved
hoses are fitted incorrectly, damage or
danger may result.
The hoses are supplied with quick release
couplings that must be correctly fitted
before starting the pump. Due to these self-
sealing couplings, the hoses will remain
filled with oil when not in use.
Damaged hoses should not be used, due to
the high pressure of the oil, a burst or leak
is hazardous, any damaged hose must be
replaced and returned to the supplier for
testing and repair before reuse.
1.3 Submersible Pumps
The S3T has a vortex impeller with 3”
discharge. This pump is from a wide range
of submersible pumps to suit a variety of
pump applications.
For borehole applications use slim-line
pumps,
for compact high volume
requirements use axial flow pumps, for
open water pumping use a conventional
pump with a vertical side discharge port.
To pump sewage or similar liquids with
solids or sludge content use pumps with
vortex
impeller and for maximum
performance with clean water use pumps
with a channel impeller.
All pumps are driven by simple and reliable,
compact hydraulic motors and are fitted with
mechanical seals.
2. SAFETY PRECAUTIONS
2.1 Safety Symbols
Safety instructions within this manual are
marked with the following symbols:
This symbol refers to general
mechanical aspects of safety.
This symbol refers to electrical
safety.
This symbol gives warning of a
hazard to the pump itself, which in
turn could cause a risk to personal
safety.
2.2 Submersible Pump Safety Precautions
2.3.1 Ensure that the hydraulic power supply is
turned OFF and disconnect the hydraulic
hoses from the pump before working on the
pump.
