1.2 Explanation of warning symbols
To be used with all safety instructions that must be followed. A failure to follow the
instructions may result in injuries and/or incorrect machine operation
Important technical and safety instructions are shown by symbols. If the instructions are not performed
correctly, it can lead to personnel injuries or incorrect function of the pump.
1.3 Field of application
It must be ensured that the inlet gas cannot react with the water and create aggressive bonds that break
down the pump's components.
For other operating data, see specifications.
• The pump must only be used with media that is not aggressive to the pump's materials. See section 7
for components and materials.
Inlet of foreign objects can damage the pump
The pump is designed exclusively to pump gases, including atmospheric air
1.4 Disposal
Samson’s liquid ring pump is manufactured so that most of the device can be reused/recycled.
Samson Pumps offer users of the company’s pumps the option of returning used pumps to be restored or
scrapped.
Alternatively, the pump must be taken apart and sorted into its separate components, by the customer
(see section 7 for the pump’s material).
These components must be disposed of in accordance with national regulations.
WARNING!
Avoid cavitation of the pump! For further information, see instruction manual for the
Samson Pumps vacuum control valve (optional)

2.3.7 Correction factor - Temperature
DOC1628005_1A
2.3.8 Correction factor - Wet and dry gas
Normal atmospheric air contains water vapor. In this case water will condense inside the pump and will
create a higher flow.
Below you can find a correction factor table for the performance based on condensing gas with an inlet
temperature of 50°C 100% saturated and service liquid temperature of 15°C.
Suction pressure % Vacuum 80 70 60 50 40 30 20
Correction factor wet gas KWet 1,34 1,28 1,15 1,13 1,09 1,08 1,07
The performance of the pump can thereby be calculated as:
VWet= VDry xKWet
When the temperature of the water exceeds 15°C,
the pump’s capacity will be affected with respect
to the specified values.
To determine the output at a higher temperature,
the correction factor can be used.
Capacity at water temperature higher than 15°C :

The pump must not be used if it is damaged or the identification plate is missing
2.4 Handling and transport
The pump must be transported in such way that
it is not exposed to vibrations and impacts that
can overload the bearings.
The pump must be inspected for damages upon
delivery. If the pump is damaged, it must not be
used and the damage must be reported to the
manufacturer.
Ensure that the pump’s identification plate
is intact and that the marking of the pump
corresponds to its use.
The pump must only be handled using approved
lifting eyes, in accordance with nationally
applicable regulations and only in a vertical
motion.
The pump can be transported in the following
ways:

A failure to comply with the requirements for storing the pump may result in internal
damage to the device
2.5 Pump storage and draining procedure
If the temperature is below freezing point of the service liquid, it could damage the pump
Under these conditions, the pump must be drained completely
All plugs and protective covers must be fitted during storage
The pump’s water is drained on delivery, and the pump can be immediately stored in accordance with the
technical specifications.
After operation, the pump can be stored for 30 days without further action.
If the pump remains out of operation for a longer period of time after use, its water must be drained.
Drain the pump in C1or C2. The pump can be fitted with valves in the draining connections. See below.
Draining during normal operation, see chapter 5.

Together with the air there will be a water flow out of the pump up to 6 m3/h.
The water will be separated from the air in the liquid separator.
Depending of the size of particles, water will be carried with the water when the air velocity is more than
3-4 m/s.
The inlet speed to the separator can be more than 50 m/s and this must be reduced to 3 m/s.
Below you find an illustration showing how to reduce the speed and control that no water will be in contact
with the high velocity air stream. The round velocity reducer can be placed inside any tank geometry.

With a temperature difference on 20°C it is typical to have a radiator affect in a truck on somewhere
between 5 to 20 kW depending on the construction.
The table below shows truck radiator effect at a temperature difference of 20°C.
3.2 Air cooling with fan cooler
Example:
We have a tank with 300 litres of water corresponding to 300 kg. The heat input is 30 kW.
How long will it take to heat it up from 20°C to 40°C ?
tsec =Cp x m x Δt
Q
tsec =4,2 x 300 x 20 = 840 s = 14 min
30
The temperature will continue to go up until the steel construction can absorb the heat and transfer it to
the surroundings.
tsec =Time in seconds
Cp=Heat capacity of the media. Water= 4,2
Δt =Temperature difference
m=Mass of the media heating up [Kg]
Q=Heat input in [kW] See specifications, chapter 2.2
Compression of air inside the liquid ring pump will create heat that is transferred to the water.
Therefore, it can be necessary to install a fan cooler depending on the expected use, the climate etc. The
time it takes to heat up the water also depends on for example ambient temperature, suction pressure,
amount of water and the cooling effect in the truck itself.
The operation temperature will go up until there is a balance between the heat input and the heat output.
So basically, there are only two things that can lower the operation temperature. Reduce the heat input or
increase the heat output.
The amount of water has no or only a little influence on the final operating temperature. The truck itself
will work as a big radiator and if there is a huge amount of water in the liquid separator and thereby good
contact area between the water and the steel tank, it will give a higher cooling effect. This in combination
with low ambient temperature and short time of operation, could mean that the truck can operate without
any additional cooling.
In general, the time it takes to heat up the water can be calculated from the formula below.

3.3 Fan cooler
The fan cooler will increase the heat output from the construction and thereby stabilize the temperature
at a lower level. However, this cooler will use the air to cool down the water and therefore we will always
see that the temperature will be stabilized above the ambient temperature. It’s very simple to find the right
cooler based on the curves from the cooler manufacturer. Typically you will find the cooler capacity as kW/
Δt meaning for example 1.5 kW cooler capacity each °C in temperature difference between the water and
the air. Note that the water flow through the cooler will also affect the cooling capacity.
DOC1627392
Typical fan cooler characteristic.
Practical calculation example:
The truck is used mostly to work with an operation pressure around 70% vacuum. From the technical data
sheet, we find the heat input from the pump to be 68 kW.
The liquid separator is built inside the slurry tank with a good contact to the product and a radiator effect
estimated to 20 kW with a temperature difference of 20°C.
The truck will work with ambient temperature up to 28°C during the summer and we will accept a maximum
temperature on 40°C.
First, we have to reduce the radiator effect based on a temperature difference of 12°C.
Qout Truck = 20 x
12 = 12 kW
20
The total cooling effect required is thereby:
Qout Pump - Qout Truck = 68 - 12 = 56 kW

3.4 Water consumption
It is possible to design the liquid separator so that almost 100% of the water is separated from the air.
However, the air will be heated up and thereby it can contain more water. Also, the relative humidity will go
up and end near 100%.
So, the air will flow into the pump with maybe 50% relative humidity at a low temperature and be
discharged at a higher temperature and humidity. Therefore, there will be an evaporation from the system.

3.5 Dome valve system
The liquid ring pump can handle liquid and particles in the inlet but it is of course
recommendable to avoid this.
A dome valve or floating valve will ensure that the suction will be closed when the liquid
level reaches the top of the tank.
In many situations there will be foam on the liquid surface inside the tank. It can be
difficult to avoid that this will be transported into the suction line before the dome valve
will close.
Therefore, it will be recommended to make a combination of a filter and dome valve as
illustrated below.
The filter will prevent particles lifted by the foam to enter the pump.

Summary
We need to find a fan cooler that can transfer 56 kW with a temperature difference on 12°C.
That is 4,6 kW/°C.
If we for example accept a higher temperature, for instance 48°C, we will have full cooling effect from the
truck on 20 kW and a cooling requirement on 48 kW. The fan cooler we need to find is thereby on 48/20 =
2,4 kW/°C and a big difference to the bigger model calculated above.

Maximum discharge temperature 70 50 40 30
Note that the temperature of the gas inside the pump will heat up the water and the water surface therefore
will become a higher temperature than the measured temperature on the discharge side of the pump.
Cavitation will therefore start at a lower temperature and the maximum discharge temperature of the water
must be kept lower.
DOC1627471
DOC1627471
Below you find the boiling point of water as a function of the pressure.
When the temperature reaches the boiling point of the water, steam bobbles will be created in the liquid
ring.
These bobbles cannot exist when they enter the discharge side of the pump and therefore they will
collapse. The impact force on the surface of the rotor and flow plate will damage the pump and can lead to
a total breakdown. It is a very harmful situation that must be avoided.
It is the combination of the pressure and the temperature that will lead to the cavitation. Therefore, it is
recommended to install 2 vacuum control valves, see illustration below that shows a clockwise rotating
pump. If counter-clockwise rotating pump, mount in opposite manifold.
3.7 Water requirement
During operation it is normal that small amount of product will enter the pump, or the gas will react with
the water which can become aggressive.
Drain the liquid separator and refill with fresh water, if the water has become aggressive.

4 INSTALLATION AND START-UP
4.1 Securing the pump
The pump must be installed on a stable foundation, which must be level and stable, so that the pump is not
twisted or exposed to a profile distortion.
The pump must be installed with M16 bolts on all four legs, which must be tightened to 180 Nm (A).
Immediate before connecting the pipes, remove protective covers. Connection of the pump’s suction and
pressure pipe connections must be made with a gasket in between (C).
The M16 bolts must be tightened with 180 Nm (B).
In order to prevent tensions in the pump, the pipe connections (A) must be tensionless while tightening the
bolts.
4.2 Connections to the pump
• Check for foreign objects in the pump and physical damage on pump
• Gaskets to be handeled with highest degree of caution
• Gasket and sealing surfaces must be cleaned before assembly
