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:
DOC11093A

Ocean Master 450 11
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
The pump’s service liquid 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 service liquid must be
drained, and the liquid supply to the pump must be shut off.
When emptying the pump, it is important that all chambers inside the pump are emptied.
The pump can be fitted with valves in the draining connections. See below.
After use with sea water it is recommended to drain and flush the pump with fresh water.
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

3 DESIGN OF A SYSTEM
DOC1627418_1
Pos. Description
1Liquid ring pump
24-way valve
3Pressure gauge
4Regulating valve
5Water pump
6Pipe connection - Critical pipe
7Stop valve

Ocean Master 450 13
In a fish handling system, where the pump is working without liquid separator, the piping can be critical.
The pipe pos 6 will be a combination of a discharge and a suction pipe and the design of this pipe is very
important.
Figure below shows a standard setup. When the pump is discharging, the tank pipe pos 6 will carry a
mixture of air and water, which is the sealing water supplied to the pump. When the 4 way valve pos 2
change position this pipe becomes the suction pipe and water that is in the pipe will enter the pump. In
normal situation a small vibration will follow when the pump is injected with water on the suction side.
It is important to keep a high velocity > 30 m/s in this pipe and design it as short as possible without
“water traps”. The velocity can be calculated based on the nominel flow and the pipe diameter.
Another and safer solution is to place the 4 way valve closer to the fish tank as illustrated below.
3.1 Piping
DOC1627418_2
3.2 Service liquid adjustment
In order to get the correct water pressure to the pump it is recommended to build the supply line as
illustrated below. For correct service liquid supply, the neutral pressure needs to be adjusted to between
0,6 and 0,8 bar(g) when the pump is running unloaded.
DOC1627418_3
3.3 Service liquid pump
The water pump must be able to have a flow on 3000 l/h at a pressure at 1 bar(g) in order to get the full
performance of the liquid ring pump.

14
3.4 Pump performance
The pump performance can easily be found using the performance curves.
• Plot in the lifting height and add the calculated pressure drop in meter water column.
• Follow a horizontal line till you meet the performance curve.
• Go vertical down and read the performance.
For practical design it is important that the speed in the pipe system etc. is verified against a fish handling
perspective.
Note: 1 meter water column = 0,1 bar = 100 mbar
DOC1627419_1

Ocean Master 450 15
3.5 Pressure drop
The pressure drop in the system depends on the flow and on the other side the flow will depend on the
pressure drop.
It is a mathematical iteration process, therefore in practice we need to start the calculation with a guess.
As a start value for the flow it will be recommended to use the flow corresponding to the static lift + 1
meter corresponding to 0,1 bar or 100 mbar.
DOC1627419_2
It is possible to calculate the pressure drop manually, but there is a lot of free programs for download.
Use the system data to evaluate the pressure drop used as start value.
The calculated value can be used to find out if the start value is too low or too high.
Example
If the calculated pressure drop is far below the start value (100mbar) make a new calculation with the flow
based on for example 50 mbar. Start with the static pressure + 50 mbar and find the flow from the curve.
If the calculated pressure drop is far above the start value (100 mbar), make a new calculation with the
flow based on for example 200 mbar. Start with the static pressure + 200 mbar and find the flow from the
curve.
NOTE: Pressure drop above 100 mbar indicates that your pipe diameter is too small for the pump you are
using.

16
3.6 Service liquid requirement
If sea water is used as sealing water, it is recommended to flush the pump with fresh water after use and
drain the pump afterwards.
Before the pump is started again, remember to fill the pump to about shaft height before start up.
Otherwise the pump will be started with dry run of the mechanical shaft seals, which will shorten the
lifetime.
A drain valve mounted in the pump will help to identify the correct level of water. See below.

Installation requirements must be observed, otherwise there is a risk of damage
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 M12 bolts on all four legs,
which must be tightened to 60 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 M12 bolts must be tightened with 60 Nm (B).
In order to prevent tensions in the pump, the pipe connections
(A) must be tensionless while tightening the bolts.
4.3 Connecting the service liquid
The service liquid must be connected to the pump at the hose connection, see
illustration.

4.5 Prior to start-up
• Do not start the pump without service liquid, as this will damage the mechanical shaft
seals
• Do not start the pump if it is completely filled with service liquid
• Do not start the pump before the grease cartridges have been activated, as this can
damage the pump (if equipped)
• Stop the pump immediately if the rotational direction does not correspond to the
directional arrow
• A failure to follow the above guidelines may result in damage to the pump
4.6 Direction of rotation
