3. MACHINE DESCRIPTION
3.1. General description
The SE 40C is a self-cleaning centrifugal separator for cream clarification.
The machine is constituted by a cast-iron frame, painted or coated by stainless steel, on which
are installed the following components:
- two shafts with a couple of helicoidal gears with orthogonal axes, an hydraulic
coupling, ball bearings, etc.
- motor
- manual brake
- sight glass to check the movement of the gear (bowl) and oil gauge glass
- bowl
- anular cyclone collecting the sludge discharge and the bowl protection cover
- inlet-outlet flow unit
- device for operating water injection in the bowl.
The supply includes also the electric panel, the operating water system (surge tank, filter,
pressure reducer and pressure switch) and a set of special spanners for the bowl.
3.2. Operating principles
The product flows (fig. 3.1) into the bowl through feed pipe (1) and into the distributor (2) it
undergoes acceleration until it reaches the bowl rotating speed. The distributor (2) conveys the
product to the disks stack (3) where the separation between light and heavy phase takes place.
Light phase flows to the centre of the bowl and heavy phase flows to the bowl outer diameter.
They rise in the disks stack and reach the two upper chambers of the bowl. Here two fixed
centripetal pumps (4, 5) convey them under pressure to the outlet pipe lines (6) and (7).
The separated solids are collected in the peripheral part of the bowl (8) and they are
periodically and automatically discharged through the discharge holes (9) to maintain the
required separation efficiency. The sliding piston (10) is kept in the closed position by the
pressure produced by the water in the chamber (11). Injecting the water (13) into the opening
valve (12) the chamber (11) is emptied, the piston goes down and the solids are immediately
ejected. By interrupting the water (13) and injecting the closing water (14) into the chamber
(11), the sliding piston goes back to the closed position.
The periodical solids discharge is carried out automatically by means of a programmer unit
regulate by a PLC which controls the opening and closing water solenoid valves. Various
automatic, independent working cycles may be selected to perform partial and/or total
discharges during separation and washing. By setting the PLC it is possible to regulate the
discharge quantity, the time between two following discharges and the sequence between
partial and total discharges. The programmer unit can realize also the following functions:
automatic bowl closing during the starting-up phase; stop feeding during total discharges;
rinsing of the bowl external surface and of the protection cover internal surface, before and
after the discharge; semiautomatic realization of partial and total discharges and of bowl
overflow (during cleaning in place); product ricirculation.The discharge of solids collected in
the bowl by mean of partial discharge does not involve the stopping of the separating process;
actually it takes place at the rated revolving speed and without interrupting the product

Chapter 3
SEITAL S.r.l. Rev. 1 of 14/01/97
Page 3-2 Use and maintenance handbook: Centrifugal separator SE 40CX
feeding. On total discharge, before the discharge takes place, there is the closure of feeding
valve with interruption of the product feeding (controlled by the PLC) and the stop of feeding
pump.
The ejected sediments are collected into an outer anular chamber where they are drained away
by gravity through a pipe.
Bowl feeding is carried out through a closed pipe line with outlets of the product under
pressure, by means of two centripetal pumps and without seal gaskets between fixed parts and
rotating parts. On inlet-outlet pipe lines are inserted valves and instrumentation necessary to
control and regulate the separator (micrometric adjusting valves, butterfly valves, sanitary
pressure gauge, sample cocks, etc.).
The electric control panel is equipped with a mimic with optical signals of the separator
working main phases and an ammeter which indicates motor current absorption.

3.4. Noise level
The machine has been subjected to a noise emission test with reference to the noise test code
included in Annexe A of the standard prEN 12505.
The determination of noise emission values (sound pressure level) has been done with empty
machine, rotating at the operating speed. Care has been taken to ensure that the any electrical
conduits, piping or air ducts which are connected to the machine do not radiate significant
amount of sound energy.
The measurement has been done at 1,0 m. in front of the machine and 1,6 m. above the floor.
A-weighted time-averaged emission sound pressure level: dBA
3.5. Destination and foreseen place of use.
The machine must exclusively operate inside a closed place, which must possess features in
conformity with the prescription of this Manual (see § 5.1).
The floor must be plane, without asperities, sufficiently solid to avoid sinkings.
3.6. Improper uses and contra-indications
• Never use the machine to separate liquids which have different characteristics (density,
temperature, corrosion, etc.) from those specified.
• The bowl has not to rotate at a higher speed than the maximum operating speed (6.500
rpm).
• The bowl has not to rotate empty. It is allowed to put into rotation the empty bowl for a
period of 15 min. only in starting phase.
• Never elude or disactivate the safety shields.
• Never use the machine if it is damaged.
• Do not connect the machine to an electric panel that is not specifically supplied by

4. LIFTING, TRANSPORT, STORAGE
4.1. Machine delivery
The whole material is accurately checked from the manufacturer before the forwarding.
For transport and lifting operation the bowl is separated from the rest of the machine; this to
preserve the integrity of the rotating parts of the machine.
When receiving the goods check the machine has not been damaged during transport or that
the eventual package has not been tampered with subsequent removal of internal parts. Verify
therefore that data desumed from the accompanying documents correspond to forwarding
data.
When disassembling it is advised to accurately sieve the packing, to avoid that parts, missing
at first sight, are not remained in the packing material.
If damages or missing parts are noticed, immediately inform the carrier and the manufacturer
showing photographic documentation.
4.2. Packing and unpacking
The packing conditions are defined with the customer in relation with the distance and the
chosen mean of transport. The machine can be transported without packing.
In case of packing this is constituted by a wood box.
The machine parts must be assured to the level ground (by brackets or other) to prevent every
horizontal and vertical movement.
The sheets affixed outside the packing contain the following information:
• Manufacturer
• Address
• Gross weight
• Case dimensions
• Means of lifting
• Lifting points
UNPACKING
Carry the packed machine closest the place selected for installation.
Remove the plastic protection to free the machine.
Conditions of packing elimination (if present):
Wood: not pollutant material, to correctly recycle.
Plastic: pollutant material to not burn (toxic fumes) neither waste in the environment;
eliminate in accordance with the law in force in the user country.
4.3. Lifting and transport of the packed machine
To lift the packing can be used the following means:
• lift truck;
• bridge crane, crane or hoist with sling.

Chapter 4
SEITAL S.r.l. Rev. 1 of 14/01/97
Page 4-2 Use and maintenance handbook: Centrifugal separator SE 40CX
LIFT TRUCK
Use a lift truck with:
• capacity higher than the weight of the machine+packing (reported outside the
case);
• forks with length higher than 1500 mm.
Insert the forks under the level ground in central position, where signed by the suitable
triangles on the case (fig. 4.1), and keep them at the maximum distance one from the other.
SLING
Must be used ropes or bands in good conditions (neither damaged nor deteriorated) having
guaranteed capacity higher than the weight of the machine+packing (reported outside the
case).
Pass the two ropes outside the “case feet” to avoid the sliding of the ropes towards the centre
of the case (fig. 4.2).
4.4. Lifting and transport of the machine without packing
ATTENTION
Danger of damaging the machine during transport
The machine transport on the road must be performed without the bowl to avoid damaging of
the vertical shaft and/or ball bearings.
To lift the preassembled unit on base frame (fig. 4.3), use a lift truck having guaranteed:
- capacity higher than the weight of the machine (ca. 1.700 kg.);
- fork with length higher than 1.500 mm.
Insert the two forks (fig. 4.3) from the side A of the base frame in such a way that they reach
the edge of the opposite side, or insert them from the side B (motor side) with the caution of

insert them as much as possible overall dimensions permitting. If the forks are inserted from
the side B, check they can lift both the transverse beam of the base frame in which the
machine is fixed.
To lift the bowl (fig. 4.4) a particular procedure must be followed:
- screw on the bowl (2) the threaded rod with nut (1), used for disks compression;
- apply on the nut (provided with handles) the lifting ropes having guaranteed capacity
higher than the weight of the bowl (ab. 310 kg);
- lift the whole with a bridge crane, crane or hoist.

ATTENTION
Danger of machine turnover
Danger of impact and squashing for people
During lifting and transport must be used great caution to avoid injury to people and things.
This operation must be performed by expert personnel.
Verify that nobody is exposed to a risk in danger zone.
WHEN LIFTING ALL THE AREA SURROUNDING THE MACHINE MUST BE
CONSIDERED DANGER ZONE.
Until the groups (bowl, separator) are not completely lifted it’s better to verify the correct
balancing of them. The lifting must be performed with continuity (without impulses).
Keep the load lower than possible during movements, both for a better load stability, and for a
higher visibility.
The manufacturer does not answer about breakages due to the transport of the machine after
the delivery.
All the elements that are potentially moveable or not resistant to his weight must be securely
fixed to the machine to prevent dangerous disjunctions or unbalancings.
For the machine not packed is prescribed a covered transport.
4.5. Warehouse storage
The machine storage, with or without packing, must be done in a place which has the
humidity and temperature conditions reported in § 5.1.
If the machine remains unused for a long time (more than 3 months), after it has already
worked al least once, perform the following operations:
- accurately clean the separator;
- dry with clothes and greased all the bowl parts and the unpainted parts of the machine, to
avoid corrosions;
- keep the bowl in a dry place;
- to avoid the gaskets become brittle, preserve them in a cool, dry, dark and dust-sheltered
place;
- discharge lubricant oil and accurately clean the gear chamber;
- disconnect the inlet-outlet pipes of the product;
- close the operating water cocks and check that losses are not present.
When starting the machine follow the instructions reported in § 7.
