Seal Gas Booster
The magnetic booster is used to ensure seal gas flow to centrifugal compressor
start-up or when compressor is in pressurized shutdown.
The booster is realized as a seal-less reciprocating compressor driven by a
pneumatic motor.
The pneumatic motor move the driving leverism jointly with a Taurus shape
permament high efficiency magnet.
The piston of the reciprocating compressor is dragged by the external magnetic
field without any mechanical
link. In this way the booster has a completely sealed construction without the
need of any seal system.
Booster assembly shall be suitable for horizonthal or vertical mounting.
Vertical mounting anyhow will be realized maintaining horizonthal movement
of the booster piston.

APPLICABLE STANDARDS
The applicable codes and standards are:
- European Directive No. 97/23/EC (PED)
- European Directive No. 94/9/EC (ATEX)
- ASME VIII Div. 1
- ANSI B16.34
- NACE MR01.75
As an option can be added a 1-stages or a 3-stages ball valve whose function is to open/close
the seal gas inlet to the booster and the two seal gas outlets to centrifugal compressor.

PRINCIPLE OF OPERATION
When the Seal Gas Booster is powered pneumatically, the
piston in the pneumatic cylinder double acting, connected
to the piston in the high pressure cylinder by means of a
connecting rod, it reciprocates the high pressure piston
compressing the gas contained in it coming from the process
connection of the flange input, creating in this way a
continuous flow and a pressure differential drop between
inlet and outlet of the Seal Gas Booster.

Installation
Only qualified personnel can install the device. When coupling, follow the security standard in force for this
kind of operation both for personnel and machinery. In detail, follow every particular prescription indicated in
this instruction handbook.
Anyway, respect the following prescriptions:
Before assembling check the Seal Gas Booster preservation state.
Qualified personnel must assemble the pneumatic and mechanical parts.
Respect every safety standard in force when connecting to energy sources (electrical, pneumatic, and so on).
Install the Seal Gas Booster to the floor in horizontal position or wall position keeping horizontal movement
of the piston.
Lock the Seal Gas Booster to the plan using the relevant holes by designed screws or tie rod.
Connect the main air supply to the inlet threaded connection in the front side of the seal gas booster. and also
the air ventilation to the ventilation device (pressure reducer or snubber element) located in the left side of
the booster housing.
WARNING: For the correct operation of the seal gas booster the connection of the air ventilation is mandatory!
WARNING: For the high temperature booster HT series the air ventilation must always be present even if the
booster is not operational!
Connect the pipe media to the lateral flanges blocking the tie rods operating in cross after having installed the
ring joint gaskets.
WARNING: Make sure that INLET / OUTLET flow direction indications are respected to grant the correct
working of the system!
WARNING: use only filtered process fluid not to damage the System Booster (3µ grade min. suggested).
System start-up - Shutdown
Before the Seal Gas Booster starts check its correct functionality:
• Check if the pneumatic connections are correct.
• Check if the air supply medium (pneumatic drive booster) or the electric power supply (electric drive booster)
are correct.
Only for pneumatic drive booster: use only filtered and lubricated air.
• Max. pressure and temperature values must not exceed the nameplate data,
• Check if the Seal Gas Booster movement is regular (cycles/min) as indicated on the system nameplate data.
• Check the air ventilation correct setting (0.2÷0.8 bar suggested) applied to the ventilation device (reducer
pressure or snubber element).
START-UP
1. Connect the ventilation air supply (pressure reducer or snubber element).
2. Connect the power supply drive (air or electric) of the booster.
3. Connect the process gas fluid to the inlet booster increasing gradually the fluid pressure up to the operating
value.
SHUTDOWN
1. Disconnect the inlet process gas fluid decreasing the pressure gradually.
2. Disconnect the power supply drive of the booster (air or electric).
3. Disconnect the ventilation air supply (pressure reducer or snubber element).
