HELIX 300 SYSTEM with hydraulic motor
Displacement 40 cc/rev Filtration class 20/18/13 (ISO 4406)
Continuous pressure 1420 bar Optimal viscosity 15-30 cSt
Max. drain line pressure 1 bar Max. viscosity 1000 cSt
Fluid HLP Max oil temperature 280 °C
1Motor in continuous service. With pump operating within the prescribed operating limits, the actual working pressure is always lower. | 2With
reference to the temperature of the oil present in the main circuit.
2.6. Noise
The sound pressure and sound power values of the pump are given inside the HELIX vacuum pump/compressor manual.
The noise value in Db varies according to the system realised, and the supply and suction pipes. Please remember to use Personal Protective
Equipment (headphones) to reduce the effect of noise.
Sound power verification cannot be performed without completion of the vacuum line system. This verification is the responsibility of the final
installer.
Apply these prescriptions carefully.
3.1. General recommendations
When transporting the unit, fasten appropriately. Rest the unit on stable points.
Installation and maintenance must be done with the unit stopped, power transmission disengaged and by skilled personnel.
Work on the unit dressed appropriately (avoid ties, wide sleeves, necklaces, etc.) and using suitable protective equipment (gloves, goggles,
shoes, etc.).
Before any maintenance operations, stop the unit and bring the system back to atmospheric pressure.
To intervene on the unit, all the components of the unit must be stopped and cold.
To prevent errors and hazardous situations, establish what each operator is responsible for in the different maintenance operations.
Final manufacturer must make the transmission inaccessible by means of a fixed guard or interlocked movable guard. Do not start the unit up
without the safety devices required for the transmission parts. Replace damaged protections.
Operators working in the vicinity must avoid prolonged exposure to the noise emitted by the suction equipment if they are not equipped with
suitable protection (PPE recommended: ear protectors).
The components can reach very high temperatures (over 90°C) during operation. Use all means necessary to avoid contact.
During vacuum operation, avoid accidental intake of solids: they can be projected at high speed through the discharge manifold, damaging the
silencer.
Safety valves: direct the air flow away from operators.
Do not use the unit beyond its limits of use: risk of breakage with consequences for the operators.
Do not exceed the rotation speed and maximum pressure given in the technical table in paragraph 2.4.
Based on the final use of the unit, the insertion in the housing machine and the typology of the same, the designer of the housing machine must
apply safety signals (pictograms) to warn the operator on the risk still present. These pictograms essentially refer to three categories:

signals prescribing the use of Individual Protection Devices (IPDs) such as, in this case, the use of gloves and ear protectors;
signals indicating to pay particular attention to the dangers related to the machine’s components, such as: risk of dragging in the
transmission equipment and contact with hot surfaces;
signals indicating specific parts of the machine for an easier identification, such as: greasing points, oil tanks, etc.
3.2. Intended use
HELIX SYSTEM units are intended to be used for loading and unloading liquid material. The units are used for liquid waste transport, septic tank
cleaning and other industrial applications.
The HELIX compressor / vacuum pump is suitable for conveying pollutant-free gas such as suspended oil or water: this is enabled thanks to the
absence of contact parts and thus lubrication oil inside the compression chambers.
The installer shall use all possible means to prevent foreign objects and liquids from entering the vacuum pump/compressor.
The entry of foreign objects or liquids may damage the vacuum pump/compressor
E Avoid suctioning of toxic materials and flammable or explosive gases as the internal components can reach high temperatures.
Avoid suctioning of toxic materials and flammable or explosive gases as the internal components can reach high
temperatures.
Do not use the unit beyond its intended operating limits (see par. 2.4): risk of breakage and possible transmission damage.
4.1. Inspection on receipt
When goods arrive, make sure all items are intact: they may have been damaged during transport.
Remove the packaging by removing material that may become hazardous if vacuumed.
Make sure that the HELIX vacuum pump/compressor has the identification plate. Pumps with no plate are considered anonymous and potentially
dangerous: they must, therefore, not be used, otherwise the manufacturer cannot be held liable for any event.
4.2. Warehouse storage
If the unit is not expected to be used for a long time or in the case of intermediate storage of a non-new unit, observe the following:
Perform thorough cleaning of the unit before storage, using the flushing kit. The procedure is given in paragraph 5.1.
Store in a closed and dry place.
During storage, rotate the input shaft three or four turns every two weeks to keep the internal gears lubricated.
4.3. Handling
Verify before each move that lifting equipment is suitable for the capacity. Check the weight of the unit given within this manual.
Harness the machine with suitable straps / chains near the main body, paying attention to the position of the mass center of gravity to ensure the
load stability.
The unit is equipped with hooking devices: two sheet metal eye rings and an eyebolt (fig. 4.1).
The hooking devices are screwed into the top of the unit, at a position equidistant (approximately) from the center of gravity of the masses of the
unit, to ensure stability during handling.
The unit has no components or accessories that are potentially dangerous, or that can move during lifting, handling or tilting.
When moving, do not lift the packaging or the machine more than 50 cm from the ground. Proceed with the final lifting only near the installation
point.

4.5. Assembly - Power transmission
For HELIX SYSTEM units, the permissible power transmissions are:
Direct transmission (e.g.: from agricultural cardan shaft)
Oil hydraulic transmission (for versions with hydraulic motor).
Protect with a fixed or interlocked guard and signal with pictograms the power transmission chosen and applied by the final installer, if there is
the possibility that the operator will come into contact during handling.
CARDAN TRANSMISSION
Use telescopic cardan shafts.
Fig. 4.3
In order to achieve uniform motion of the driven axis, the following conditions must be met (see Fig. 4.3):
Equal joint angles α and α1 of the two joints;
The inner forks of the joints must be coplanar;
Driven shaft and coplanar conductors.
It is also advisable to work with small joint angles (max 15° at 1000 rpm and max 11° at 1100 rpm) and to stop the transmission during
maneuvers in which the joints work at large angles (steering or lifting).
Respect the direction of rotation of the unit. Comply with the cardan shaft manufacturer's directions.
It is the responsibility of the final installer to provide for suitable guards, in presence of transmission shafts exposed during normal operation.
In any case, the installation, by the final installer, must meet current accident prevention regulations.

4.6. Start-up and preventive checks
It is necessary to check some items before placing the unit on motor vehicles:
Sufficient size of opening through which to pass the module.
Stability of the vehicle before and after placing the module. The assembled unit must be accessible for maintenance (longitudinal and
transverse tilt max 3°).
Verification of the total center of gravity (after placing the module on-board).
Any leaks or refill points for liquids and/or lubricants are reachable for activities necessary for operation.
Before using the unit for the first time, or when using it again after periods of inactivity, check that:
All components, especially the guards, are present.
All components are firmly attached.
Lubricant oil does not leak from the unit.
If the module is placed on-board a vehicle, it is appropriately fixed and not free.
The pneumatic actuator of the 4-way diverter, if any, is properly fed and occupies one of the two limit switch positions.
The hydraulic pump, if any, is properly fed. Dry operation may damage it (risk of seizure).
There are no obstructions along the suction hose.
Evidence of any unsuitable conditions for operation involves machine shutdown, or non start-up or a precautionary
start-up in safe conditions.
Misuse, negligence, attempted repairs or modification by unauthorized personnel, will void the warranty conditions and terms.
To ensure optimal working condition of the HELIX SYSTEM unit, regular maintenance of the unit is recommended.
Use the necessary personal protective equipment before checking the performance of the unit (checks with the unit running). The noise level can
exceed 90 dB.
Any maintenance interventions must be performed when the machine is cold, stopped and switched off.
Wear the required PPE (e.g. gloves, etc.) during maintenance.
All disassembly and reassembly operations must be done exclusively by qualified, trained personnel.

Perform the first oil change after 500 hours. Every 5,000 hours thereafter, but no more than 12 months.
Check the oil level in both boxes (front/rear) with the machine cold, stopped and turned off. Oil level must not drop below the minimum: risk of
rapid wear of internal components.

Deterioration of the internal lip seals causes the oil level in the boxes to drop. It is recommended that the oil level be checked often: daily or, at
most, weekly since frequent topping up indicates seal wear.
Slowly pour the required amount of oil into the boxes.
Resorting to a funnel and hose can make refilling easier.

The following table shows the amounts of lubricant contained in the front and rear boxes.
FRONT BOX REAR BOX
HELIX 140 0,25 l 0,5 l
HELIX 180 0,25 l 0,5 l
HELIX 220 0,25 l 0,5 l
HELIX 300 0,65 l 0,5 l
During the oil replacement, also replace the discharge plug washer.
Dispose of waste oil as required by current regulations.
Operation with insufficient lubrication can cause the internal drive transmission and retaining parts to wear rapidly and/or the vacuum pump /
compressor to lock, also damaging the transmission.
Inspection and maintenance of vacuum-pressure line components (filters, safety valve, gaskets, etc.), transmission components (belts, hydraulic
drive, etc.) and control and regulation components (rev counter, sensors, etc.), should follow the instructions of the fitter.

Oil level electric sensor
The HELIX vacuum pump/compressor is equipped with two optical oil level sensors located in the front and rear gearboxes, respectively. When
the minimum oil level is reached, the electric switch should feed alarm devices.
The oil level alarm should work only when the vacuum pump/compressor is stopped.
Fig. 5.3
Electrical characteristics of the K11 switch:
DC power supply: 10-28 V;
AC power supply: 24 V;
Protection: IP65 (IEC 529 and DIN 40050);
Working temperature: -40 to +125°C.
The switch contact for feeding the coil of a power relay is of the NC (normally closed) type. In this way (see wiring diagram above) the alarm
device is triggered even in case of accidental breakage of the connecting wires (system failure protection).
Operation with insufficient lubrication can cause the internal drive transmission and retaining parts to wear rapidly and/or the compressor to lock,
also damaging the transmission.

Stop and refill the gear boxes with the recommended type of lubricant
Internal washing of the vacuum pump/compressor
After operating in dusty environments, after accidentally aspirating liquids, or before a long period of inactivity, internal flushing of the suction
equipment is recommended. Wait until the pump has cooled down before this operation; avoid this maintenance operation on very hot suction
equipment (e.g., after a day's work) without cooling it down first.
The Flushing Kit is specifically designed for the maintenance of the HELIX vacuum pump/compressor. The use of the kit helps to limit the pump
repair costs by increasing its service life. Weekly use of the Flushing Kit is recommended, preferably at the end of the work week and whenever the
need arises. Mode of use:
Wait until the vacuum pump/compressor has cooled down before performing this operation.
Start the vacuum pump/compressor at medium speed.
Open the ball valve, allowing the flushing fluid to escape. We recommended the use of Henkel BONDERITE C-NE 5225; 5% concentration
in water.
Fig. 5.4
Flow about 0.2 l of product before closing the ball valve.
Leave the vacuum pump/compressor running for about a minute after the valve closes, allowing fluid to escape from the pump.
Stop the vacuum pump/compressor.
Drain the flushing fluid and dispose of as required by current regulations.
Recover the liquid detergent or oil residue and dispose of in compliance with the regulations in force
5.2. Suction unit
The suction unit consists of: aluminum and cast iron conveyors, 4-way valve (manual or pneumatic), flap check valve.
Provide for the necessary space to reach the manual 4-way valve to operate it.
Check which position of the built-in 4-way allows vacuum operation and which allows pressure operation.
By turning the manual lever of the 4-way valve, the vacuum pump/compressor switches from suction to compression operation and vice versa.
Avoid placing the lever halfway between the two positions so as not to have neutral operation of the vacuum pump/compressor.
In the case of pneumatic valve, refer to the note below.
Pneumatic actuator installation
Fluid Filtered, dried compressed air
Filtration ISO 8573-1 class 4 (15 microns)
Temperature °C -20 ÷ +80
Nominal Pressure bar 5.6
Maximum Pressure bar 8.4
Supply Holes G 1/4
Adjust movement speed by applying two unidirectional flow control valves. Full rotation should not take less than 1 second.
Fluid filtration: ensure a level equal to or greater than the recommended value.
In the event of pneumatic supply failure, the suction unit inverter will remain in the same position it was when the failure occurred.

Pneumatic actuator maintenance
N Normally the diverter, once adjusted at the time of installation, requires no further adjustment.
Diverter lubrication: use NLGI 2 lithium grease. Quantity: 80-100 g every 1000 work cycles.
A vent hole covered by a filter prevents overfilling of the cavity. Clean the filter if it is dirty.
For non-dried air, use temperature 0 to +80°C.
In case of interruption of the pneumatic supply, the inverter of the suction unit remains in the same position it was when the failure occurred.
The following figure shows a possible schematic view of a pneumatic connection.
Fig. 5.6
5.3. Silencers
Silencers installed at the discharge and injection line of the HELIX vacuum pump/compressor in order to ensure that the noise produced by it is
reduced.
The discharge silencer (when assailed by compressor / vacuum pump discharge airflows) is subjected to the passage of high-temperature air
that may cause overheating (over 90°C).

5.4. Air filter
The air-filter prevents foreign bodies (over a certain size) from entering the pumping system.
Maximum operating pressure -1 / +0,5 bar
Calculation pressure -1 / +4 bar
Maximum air flow rate 3600 m³/h
Degree of filtration mesh 55, with mesh hole ø 0.30 mm (at 300 μm)
The table shows the main operating parameters concerning maximum operating pressures (relative), calculation pressure (relative), air and water
flow rate, degree of filtration and weight.
Under ordinary use conditions, we recommend cleaning the filter on a weekly basis. In the event of heavy duty conditions, clean (or replace) the
cartridge every time the line performance appears to be compromised. The filter must be cold cleaned.
For routine maintenance proceed as follows.
Unscrew the eyebolts and remove/open the cover.
Remove the filtering cartridge and the relevant sealing gaskets, wash with detergent and blow with compressed air until clean.
Dry the cartridge and the entire filter thoroughly.
Reinstall the previously removed components taking care to place the gaskets correctly.
The following figure shows a schematic diagram of the maintenance procedure.
Fig. 5.7
We recommend using non-flammable detergents with passivating and protective properties.
Recover the liquid detergent and dispose of it in compliance with the regulations in force.
5.5. Cyclone purifier
The purifier prevents foreign bodies (liquids or solids) from entering inside the HELIX compressor / vacuum pump by blocking the intake line with
a metal floating ball.
The cyclone consists of a vertical cylinder, which tangentially receives the flow to be purified at high speed. As a result of centrifugal force, the
various elements contained inside the fluid are separated according to their density. The purified fluid is freed through the upper axial outlet,
whereas the material to be recovered is collected in the lower part and continuously discharged.
The following table shows the main operating parameters concerning maximum flow rate, design pressure and weight of the cyclone purifier.
Maximum air flow rate 1850 m³/h (HELIX 300), 1280 m³/h (HELIX 140-…220)
Design pressure -1/+4 bar

The unit comes with two safety valves (2”), attached to the cyclone.
The function of the valve is to prevent the pressure inside the tank from exceeding the predetermined limit. Therefore, an air discharge occurs
through the valve.
When operating the pressure relief valves, pay attention to the outflow of air.
Fig. 5.11
Safety valves are supplied uncalibrated.
For the valve in question to operate properly, you must periodically wash the internal parts. Before performing any maintenance and/or
disassembly activities on the valve, make sure that there is no pressure inside the tank.
The final manufacturer should provide the necessary space for maintenance activities on the pressure relief valves.
Maintenance and calibration of pressure relief valves should be carried out by trained personnel. Incorrect calibration
can damage the machine.
