HYDRAFLOW S6TC Hydraulic Submersible Pump
1. INTRODUCTION
The purpose of this handbook is to lay down
operating guidelines and routine
maintenance for the HYDRAFLOW S4VHL
hydraulic drive submersible pump.
Instructions and statements contained
within this handbook are given with our best
intentions and are correct at the time of
compilation. They are subject to alteration
at any time
The S4VHL pump is designed to operate
with hydraulic input flows to 95 l/m (5.7
m3/h) and a maximum pressure of 200bar
(2900psi).
Operating this unit at pressures or flows in
excess of those listed above or connecting
this unit to a closed centre or reversing

circuit will cause damage to the unit and will
void the warranty!
The pump Is capable of a wide range of
applications as it is not subject to normal
suction lift limitations.
The power unit should be selected to meet
the power requirements of the pump for the
pump duty.
Hydraulic circuits must be open centre,
single direction and have an unrestricted
return flow from the hydraulic motor to the
oil reservoir. Please review the hydraulic
schematic.

Operators Instructions for
HYDRAFLOW S4VHL Hydraulic Submersible Pump
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 noisereducing 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 selfsealing 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 S4VHL has a vortex impeller with 4”
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.

2.3.2
Check the type of liquid being pumped
before working on the pump. Residues
could be hazardous to your health. If in
doubt flush out with clean water before work
commences.
2.3.3
Personnel working on the pump unit must
always wear clean correctly fitting clothing
and safety footwear. Clothing impregnated
with oil or fuel can constitute a health
hazard through prolonged contact with the
skin and may also constitute a fire hazard.

5.1 Pump Installation
5.1.1
BEFORE attempting to operate this pump,
read the safety and operating instructions
on the power unit and in its’ handbook and
this handbook carefully.
5.1.2
Check that the power unit has been
installed correctly by reference to the
operating instructions.
5.1.3
Check the hydraulic hoses visually for
damage that may have occurred since the
pump was last run, any damage noted
should be reported and the hoses replaced
before the pump is run.
5.1.4
Ensure that the hydraulic couplings are
clean and free from grit or dust that may
prevent a leak-proof connection or
contaminate the oil. Connect the hydraulic
suction and delivery hoses making sure that
the hydraulic couplings are properly and
securely connected.
NOTE – Due to the pressure of the oil retained in
the hoses when disconnected, it is easier to
connect hoses to the RETURN circuit first.
This will allow the pressure to decay before
connecting to the pressure circuit. Always
connect the ‘Male’ hose end connection
first.
5.1.5
Lay out the hoses to the pump, ensuring
that each hose is fully uncoiled and is free
from kinks. The minimum bend radius of
the hose is 300mm.
5.1.6
If these hoses pass over roadways, ensure
that they are protected by suitable means to
prevent damage by crushing.
5.1.7
Connect the hydraulic hoses to the pump
unit, ensuring that the hydraulic couplings
are properly and securely connected.
5.1.8
Connect a suitable pump delivery hose to
the pump outlet connection and direct the
hose to the required discharge point.
5.1.9
Lower the pump unit into the liquid to be
pumped, ensuring that the pump remains
upright for best performance.
NOTE – Do not lower or raise the pump using the
hydraulic hoses, a lifting point is provided on
the pump for attachment of a shackle and
lifting chain or rope.

6.4.1
Remove (6) bolts (#19) from lifting bracket (#3).
6.4.2
Remove the remaining (2) bolts holding the
bearing housing (#22) to the volute. Use
jacking bolts to separate if necessary. The
bolts holding the volute and bearing housing
together are the same thread as the jacking
bolts.
6.4.3
Check the volute wear ring (#27) for wear. If
worn excessively (deeply grooved), remove ring
by using a puller or by tapping ring upward from
inside the volute. Replace the ring if required.
6.4.4
Check condition of "O" rings (#24 and #28) and
replace if necessary.
6.4.5
Remove (4) bolts (#9) from hydraulic motor
(#5). Because of it's extremely long life, close
tolerances, high efficiency and the relatively low
cost of a new motor, it is more economical to
replace the hydraulic motor than to rebuild if
worn. Inspect "O" ring (#10).

7. TROUBLESHOOTING
7.1 Preliminary Check List
7.1.1.
Check the hydraulic power source to be
sure the oil flow volume and available
pressure is within the range of the
submersible pump. If the power source is
capable of supplying oil in excess of the
required flow, damage will result to the
Operators Instructions for
HOSE
PORT
Manual No/Rev
W79-003E / 4
hydraulic motor and/or pump components
due to over speeding.
7.1.2.
Be sure the submersible pump is connected
to a single direction open centre power
source. The submersible pump is not bidirectional and operating in reverse rotation
can cause seal failure in the hydraulic
motor. The system must be open centre at all times (return flow from the
submersible pump motor must be allowed
to flow freely to the system oil reservoir).
Do not use hydraulic directional valves that
block the return flow when in the centre
position of the valve. This type of valve is
for hydraulic cylinder operation only and will
cause the submersible pump to stop
abruptly when moved to the centre position
of the valve. This will cause excessive
pressure on the return side of the motor
causing seal failure and possible shaft
damage.
7.1.3.
Be sure that the hydraulic hose connections
are clean and properly connected. When
using quick released hose couplers, you
muse be sure that they are completely
connected. A partly connected coupler will
result in seal damage to the hydraulic motor
and pump seal.
7.1.4.
Be sure that the pump is submerged
adequately. This is especially important for
vortex impeller pumps since the impeller is
recessed up into the top of the volute.
