Grading live fish is a fairly hard and complicated process. The system normally
consists of three to four grades where the operator can dynamically adjust the grades
on the fly. The system falls under the category of a multi input, multi output system
(MIMO). The system is operated by two to four persons at a time and it is sensitive to
any changes, a small change to the input can cause a dramatic change in the output
and it’s not uncommon that 100 of thousands of fish are graded in one session and the
size range varies from few grams to a few hundred grams.
All these factors contribute in making the system fairly complicated and hard to tune
and more often than not results in an unsatisfactory output. It requires a lot of
knowledge about the system and a lot of practice to obtain a reasonable result.
SmartFlow connects all the devices used for grading fish in a hatchery to allow for an
automatic grading. SmartFlow is a control system that optimizes the grading process
by controlling the entire process. With SmartFlow you only need one person to
operate the whole system with fundamental knowledge of grading. You can control all
aspects of the grading fromwithin SmartFlow. Enter in your desired output and the
system takes care of the rest.
Set up
When setting up SmartFlow the following
system configuration is required:
● A VAKI counter (Micro/Macro/EXEL).
● A VAKI Smart Grader
● A VAKI pump
● A VAKI density controller
● SmartFlow configured and running on
the counter.

VAKI Smart Grader
The Smart Grader delivers accurate fish grading while minimizing the impact on your
fish as they pass through the outlets. The dewatering unit distributes the fish evenly
over the width of the grader, so all 10 tracks are used effectively.
Further the inclination of the main sorting unit can be adjusted from 5-14° with an
electric actuator. The opening of the grader is controlled with electric linear actuators
that can be manually operated from a control panel on the grader or automatically
from the VAKI Counter which counts, size measures and calculates the split between
the grades. The opening for each grade is displayed on a digital display. The grader is
built in high grade stainless steel 316L and selected plastic materials that are corrosion
and water resistant.
The rollers are machined with high precision laser welding tools and balanced out with
specialized equipment. It delivers an accurate grading of the fish. The outlets are
designed to minimize the impact on the fish and can be mounted to deliver the fish on
either side of the grader. These outlets can easily be removed for cleaning. The
rotation speed of the rollers can be adjusted with a frequency controller.
The grader functions by sliding the fish between two rolls, where the distance
between them gradually widens. Where two pairs of rollers rotate away from each
other to make sure that the fish doesn’t get squeezed between the rollers, but instead
lifted up and pushed forward so they fall through in the correct place. The expansion
of the slits on both ends can be adjusted. When operating the grader you have to
keep in mind that the grades are all related to one another. One single grader gap

2. Environment
The VAKI Fish Pump is designed to work in all weathers, except for temperatures below 0 ° C
(Celsius).
Use in cold weather can cause damage to hoses and priming system. VAKI pump is built on a
chassis with 2 large rubber wheels that can carry up to 400 kg per wheel, this allows the pump to
easily move over rough and uneven surfaces. The pump is designed to move fish up to 400 g
(salmonids). It is not suitable to pump pebbles, debris or sand.
Electrical needs
An electrical expert must ensure that appropriate power socket correctly connected to the pump
power cable.
3. Explanation of Parts
VAKI Fish pump is made of aluminum and fiberglass
and provides very gentle handling of fish during
transport. The pump is 8 ".
Large handles and rubber wheels allow the pump to
easily move around uneven ground. Camlock quick
couplings are used for simple and safe connection of
hoses.
3.1
PumpBody
The VAKI pump body shell is made using a specially
molded form developed with over 20 years’ experience
in the production of fiber glass fish farming equipment.
Inside the pump body there is an aluminum impellor
which leads fish and water through the pump. The
impellor speed can be fully controlled as required, either
directly from the main pump control box or by radio
remote control.
3.2
MainMotor
The main 15kW motor drives the impellor with two belts
located under the pump body.
The motor is controlled by a frequency converter, making
it easy to regulate the pumping speed as required.
Note: If the wiring of the main power socket is inverted
the internal circuit breaker will trip cutting the power to
the main pump preventing the motor turning in the
wrong direction.
3.3
Primingmotor
The Priming motor drives the priming pump that creates the suction inside the main fish pump
before the main pump is started. This motor is 1.5 kW and has no rotation protection.
Note: If the wiring of the main power socket is inverted the priming motor may turn in the wrong
direction and must be rectified.

Primingtank
The Priming tank must be filled with water before using
the pump. The water in this tank is used to create suction
in the pumping system.
Only after running the priming pump and when water
starts flowing out the priming system outlet can the main
motor/pump can be started. There are two valves to
empty the priming tank and the other to empty the main
pump housing. In freezing temperatures, the pump may
be damaged if not drained fully after use.
3.5
Primingpump
The priming the pump is connected to the priming motor
by a shaft. On this shaft there is a coupling that is easy to
replace if necessary (see photo below). The motor is
marked with an arrow showing which direction it should
turn. It is important to empty the priming pump of water
if there is a danger of frost.
3.6
Controlcabinet
The Control unit has seven buttons, switches and lights. The
large red switch at the bottom of the cabinet is the main
power switch and can only be turned on when the cabinet
door is closed. The display tells you the speed of the pump.
There are an on and off button for priming the pump and
on the main pump.
If required, it is possible to use the priming pump while
running the main pump. The black button controls the
speed of the main pump and the red light shows if there is
power to the pump or not. The sensitivity of the speed
button can be adjusted as follows:
1 Turn off the power at the main switch and open the door of the control cabinet. The door cannot
be opened unless the main switch is turned off.
2 Turn on the power in the cabinet by turning the white shaft of the main switch clockwise. There
will now be electric current in components of the cabinet, so avoid contact with any live

3.8 Valves
On top of the swan neck there is a valve, this is used to release the vacuum formed on the suction
side of the pump. If the suction hose gets stuck open this valve to get the air into the system and
losing the vacuum and releasing the suction hose.
On the main pump outlet there is a valve to empty and discharge the water on the outlet relieving
the water pressure before removing the outlet hose from the pump. There is also a pressure gauge
on the outlet.
3.9
ConnectionsandReducers
It is not advised to use reducers with the 8“pump. There
are pumps available in different sizes. The Camlock system
is used for quick and safe connection of hoses. The
connections are designed and manufactured so that there
are no sharp edges and the fish has a very gentle treatment
during pumping. Ensure that the rubber gasket is in place,
so no air is sucked to the suction side.

Use
Before you start the fish pump.
1 Make sure the main motor and priming motor is turned off.
2 Fill priming tank with water until it is full.
3 Ensure control cabinet is closed and turn on the main switch.
4 Check the main light illuminates on the control cabinet.
5 Make sure the valve on top of the swan neck is closed.
6 Make sure the valves and lid of the priming tank is closed
START THE PRIMING PUMP
1 Check the light on the control cabinet for priming the pump is on.
2 Check the priming pump turns in the right direction. See arrows on the pump. (If priming pump is
turning in the wrong direction, the wiring must be corrected.
3 Run the priming pump until water flows out of the priming tank outlet hose.
NOW TURN ON THE MAIN PUMP
AND TURN OFF PRIMING PUMP
1 Check the lights on the control cabinet for the main pump is on.
2 Make sure the belts are not slipping.
3 Run the engine up to the desired speed.
4 If the pump sucks air and is shuddering, then turn on the priming pump and
let the priming pump run while the main pump is also running. The pump will
shake if there is air in the system, and in this case use the priming pump.
5 For optimal use, it is very important that the pump does not suck air and
shake so carefully check all connections and hoses on the suction side to
detect and fix any leaks.

Grading live fish is a fairly hard and complicated process. The system normally
consists of three to four grades where the operator can dynamically adjust the grades
on the fly. The system falls under the category of a multi input, multi output system
(MIMO). The system is operated by two to four persons at a time and it is sensitive to
any changes, a small change to the input can cause a dramatic change in the output
and it’s not uncommon that 100 of thousands of fish are graded in one session and the
size range varies from few grams to a few hundred grams.
All these factors contribute in making the system fairly complicated and hard to tune
and more often than not results in an unsatisfactory output. It requires a lot of
knowledge about the system and a lot of practice to obtain a reasonable result.
SmartFlow connects all the devices used for grading fish in a hatchery to allow for an
automatic grading. SmartFlow is a control system that optimizes the grading process
by controlling the entire process. With SmartFlow you only need one person to
operate the whole system with fundamental knowledge of grading. You can control all
aspects of the grading fromwithin SmartFlow. Enter in your desired output and the
system takes care of the rest.
Set up
When setting up SmartFlow the following
system configuration is required:
● A VAKI counter (Micro/Macro/EXEL).
● A VAKI Smart Grader
● A VAKI pump
● A VAKI density controller
● SmartFlow configured and running on
the counter.

VAKI Smart Grader
The Smart Grader delivers accurate fish grading while minimizing the impact on your
fish as they pass through the outlets. The dewatering unit distributes the fish evenly
over the width of the grader, so all 10 tracks are used effectively.
Further the inclination of the main sorting unit can be adjusted from 5-14° with an
electric actuator. The opening of the grader is controlled with electric linear actuators
that can be manually operated from a control panel on the grader or automatically
from the VAKI Counter which counts, size measures and calculates the split between
the grades. The opening for each grade is displayed on a digital display. The grader is
built in high grade stainless steel 316L and selected plastic materials that are corrosion
and water resistant.
The rollers are machined with high precision laser welding tools and balanced out with
specialized equipment. It delivers an accurate grading of the fish. The outlets are
designed to minimize the impact on the fish and can be mounted to deliver the fish on
either side of the grader. These outlets can easily be removed for cleaning. The
rotation speed of the rollers can be adjusted with a frequency controller.
The grader functions by sliding the fish between two rolls, where the distance
between them gradually widens. Where two pairs of rollers rotate away from each
other to make sure that the fish doesn’t get squeezed between the rollers, but instead
lifted up and pushed forward so they fall through in the correct place. The expansion
of the slits on both ends can be adjusted. When operating the grader you have to
keep in mind that the grades are all related to one another. One single grader gap
