2 GENERAL
2.1. Handling of slurry
CAUTION !
Remember that slurry generates potentially dangerous gases under certain
conditions. These gases (CO2, NH3, H2S, CH4) can cause intoxications and
explosions. Make sure there is sufficient ventilation in the operational area
when handling the slurry.
2.2. Intended use
The EYS separator separates fluidic slurry (which must be free of foreign objects such as metal parts, stones,
pieces of wood or cloth) into its solid and liquid fractions. The EYS separator is designed for continuous open air
operation within a temperature range of -20°C to 50°C.

3.4. Installation and mounting
ATTENTION !
If the pump feeding the separator is not an EYS pump, its capacity must
not be less than 35m3/h, otherwise the separator would not achieve its
full performance. In order to keep the frictional pressure losses to a
minimum, the pipes should have a minimum diameter of 100mm (4”).
4. PREPARATION FOR START-UP
•Check connection and tightness of feeding line between pump and separator; connection and tightness of
overflow line; free run-off into collecting tank / pool; connection and tightness of line for run-off of
separated slurry.
•Set motor protection at required rated voltage; check correct direction of rotation following the arrow on
the housing and on the motor; shut off the motor again.
•Take away the weights (for minimum back-pressure)
ATTENTION !
Make sure that no coarse foreign objects like metal parts, stones, pieces
of wood or cloth can get into the separator. Furthermore, be aware that
abrasive substances (for instance high portion of sand) will shorten the
lifetime of the machine.
5. START UP
ATTENTION !
In order to achieve satisfactory separation results, it is required to
agitate the slurry by an agitator before starting the separation
procedure.
5.1 Set-up instructions
The steadiness of the plug and the solid matter consistency at the outlet of the machine are set by changing the
position of the weights on the two levers according to the requirements.
ATTENTION !
It takes several minutes before changes of settings are realized. So
always take your time after a change and proceed only in small
steps.
Before the first start-up or after a longer idle period, switch on the pump for a moment and flood the separator to
avoid running dry matter only. Otherwise permanent damage may occur inside the machine.
5.1.1 Building up of the plug
If no plug is built up at the discharge end, make sure the discharge flaps fit closely to the mouthpiece. After
switching on the power to the separator, start and operate the pump for about 1 or 2 seconds –just long enough
to fill up the feeding line and the separator. Then wait until no liquid manure runs out any more and repeat this

SEP 2010
EYS SEPARATOR
USER MANUAL –SP SERIES
Page 7 / 14
procedure. After about five repetitions –depending on the slurry properties –a plug of solid matter will build up,
pushing the cover away from the mouthpiece.
As an alternative you may make a plug by hand: take some fibrous material like paper waste or dry separated
solid manure and stuff it firmly behind the flaps. Then start the pump without further interruption.
Depending on the solid matter content of the untreated slurry, the plug may already have the right consistency
with the first setting of the weight-loaded levers or it may be too wet or too dry.
Before switching the pump to continuous operation after building up the plug and performing an output of about
20cm of solid matter, you may have to re-adjust the basic settings. Otherwise the plug may shoot if it is too wet,
or it may stall the separator if it is too dry.
5.1.2 Settings for stabilizing the plug
Plug is too dry
Push the weights of the levers front or even remove them completely.
If the plug is too dry, it may stall the separator because it cannot be pushed
any more out of the mouthpiece.
For an easier discharge of the plug from the mouthpiece, push the weights
front symmetrically.
Plug is too wet
If the plug is too wet, it may shoot, which means that the plug is going to
melt and untreated slurry will escape.
To stabilize the plug, move the weights back symmetrically. If this does not
help, mount one more weight.
Depending on the slurry consistency, the above mentioned settings may need to be repeated several times at the
start-up of the separator until stable conditions have been reached. These steps are essential in achieving the
optimum separator performance.
5.2 Further instructions for trouble-free operation
Pay attention that the overflow (by-pass) line does not act as a siphon. Otherwise, due to the unfavorable flow
conditions insufficient amount of solid matter could enter the separator, which would reduce the throughput on the
one hand, while disturbing the self-cleaning mechanism of the screen by the solids on the other.
Therefore make sure the overflow line is free of any obstacles!

SEP 2010

If the feeding pump capacity is too high this will also affect the intake by the separator adversely.
The incoming flow must be reduced until the run-off pipe of the overflow is returning less than half of its full
discharge capacity. As a guide, the run-off pipe of the overflow should be full up to 1/3 of its cross section!
The outlet of the overflow pipe must not be below the surface of the slurry pit; this would also create a siphon
action and prevent the normal intake by the separator.
The overflow pipe must not present any bottlenecks (no kinks) and it has to be stable in shape. Otherwise it risks
to stop up or to collapse which both would increase the pressure inside the separator too much and eject the plug.
Make sure that the slurry is mixed thoroughly before separation in order to avoid shooting and stopping up of
the plug. Important note: do not mix or pump the slurry too often (particularly when the pits are of smaller size).
This would change the consistency of the slurry and make it greasy.
!
EYS Separators have a separation flange between
the gearbox and the main body. This flange houses
the seal kit that includes a multiple-seal pack in it, and
also features a window underneath where any
possible leakage would be drained. This way the
manure can in no case leak into the gearbox. Check
this window regularly for any leakages. If leakage is
observed, this means that it’s time to replace the seal
inside the plate (part# KC01). Please contact your
dealer then for a service visit.
!
EYS Seperators come with cutter screws around the
main body ath the inlet area. These cutter screws help
catch and cut long fibers before they enter the screen
zone. These screws are set to their optimum position
at the factory during the final assembly of the
machine. In order not to cause damage to the internal
parts of the machine, please do not try to change
these settings.Any adjustments that may be
necessary will be made by your dealer during the
service visits.

6. REGULAR SHUT-DOWN
1. Switch off the feeding pump.
2. Switch off the separator.
If the separator is going to stay out of operation for several days, first keep it running for one or two more
minutes before switching it off.
Depending on the kind of treated slurry, the separator can be left out of operation for a week or so without
having to remove the plug.
3. For longer idle periods remove the plug and clean the separator.
4. If the separator is going to be used at temperatures below zero, be sure to drain completely all inlet and
return pipes as well as the separator itself after finishing the separation in order to avoid slurry freezing
inside the machine. If the plug has firmly frozen in the separator melt it with hot water before putting the
separator back into operation again.
7. SHUT-DOWN FOR EXTENDED PERIODS
If your EYS Separator will not be used for a longer time, put it out of operation according to chapter 7 and clean it
according to chapter 9 “Disassembly”. Store the machine as described in chapter 11 “Storage”.
If the machine needs to be scrapped it is absolutely necessary to dispose of gear oil and electrical/electronic
components as hazardous waste. The metal parts can be recycled.

8. DISASSEMBLY –ASSEMBLY
8.1 Disassembly
It is necessary to disassemble the separator for
•Cleaning of screen and screw
•Replacing screen and screw
•Removing foreign objects in case of separator blockage
•Removing dried solid matter which is sticking to the screw after a longer standstill thus making the delivery of
solid matter impossible.
For this purpose put the machine out of operation according to chapter 8 and then disassemble it as described
below.
1. Remove all weights,
2. Do not unscrew the bolts which fix the mouth weight system.
3. Unscrew the 4 mouth flange bolts and remove the mouthpiece.
4. Do not unscrew the bolts which fix the screen guiding. It has been preset at the factory to give the
screen the right seat!
5. Unscrew the bolt of auger shaft.
6. Pull out the screen.
7. Pull out the auger shaft.
8.2 Assembly
The separator can be re-assembled in reverse order as described in chapter 9.1. Only take care that all moving
parts are working easily and check the true running of the auger before mounting the screen.
Before mounting the auger, clean thoroughly and grease the fitting surface/axle journal of the auger as well as the
bearing. Then tighten the shaft nut.

9. MAINTENANCE
Gearbox and motor are delivered ready for operation. They are pre-filled with the specified quantity of synthetic
oils and are maintenance-free for approximately 3 years. After about 10,000 operating hours or 3 years of
operation (whichever comes first), the oil must be changed.
Screen Cleaning and Wear
Screen should periodically be checked for cleanliness and any damages and/or wear. If the screen is partially
clogged by fibrous matter, clean it from both sides with a high pressure power washer or simply with a water
hose. If visible wear exists, consult your dealer for potential replacement of the screen.
Auger Wear
Auger should periodically be checked for signs of wear over time. Worn out auger would trigger premature failure
of the screen, so it is important to maintain the auger at its nominal dimensions. Worn augers can be recoated or
replaced.
Periodic Check-Up Service
It is recommended that your separator is checked and serviced by your dealer’s service team regularly. Quarterly
(every 3 months) or bi-monthly (every 2 months) service visits are recommended, depending on the number of
hours of operation per month at your installation site. Your service team would check the screen and the auger for
potential wear; clean the machine and re-assemble the auger and the screen; check for motor amperage during
regular operation, examine the gearbox for visual and acoustic hints of possible malfunction. These periodic visits
will ensure that your separator continues to deliver high performance for a longer useful life.
10. STORAGE
The EYS Separator should be stored in a closed and dry shelter when not in service for extended periods of time.
Change the gearbox oil with an anti-corrosion oil (Shell Omela 220 or equivalent); dispose of the used oil
properly. Under the condition of proper storage the corrosion inhibition remains active for at least 12 months.
