Seal Gas Booster

APPLICABLE STANDARDSThe 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/closethe seal gas inlet to the booster and the two seal gas outlets to centrifugal compressor.

3 STAGES BALL VALVE

The magnetic booster is used to ensure seal gas flow to centrifugal compressorstart-up or when compressor is in pressurized shutdown.The booster is realized as a seal-less reciprocating compressor driven by apneumatic motor.The pneumatic motor move the driving leverism jointly with a Taurus shapepermament high efficiency magnet.The piston of the reciprocating compressor is dragged by the external magneticfield without any mechanicallink. In this way the booster has a completely sealed construction without theneed of any seal system.Booster assembly shall be suitable for horizonthal or vertical mounting.Vertical mounting anyhow will be realized maintaining horizonthal movementof the booster piston.

PRINCIPLE OF OPERATIONWhen the Seal Gas Booster is powered pneumatically, thepiston in the pneumatic cylinder double acting, connectedto the piston in the high pressure cylinder by means of aconnecting rod, it reciprocates the high pressure pistoncompressing the gas contained in it coming from the processconnection of the flange input, creating in this way acontinuous flow and a pressure differential drop betweeninlet and outlet of the Seal Gas Booster.

Only qualified personnel can install the device. When coupling, follow the security standard in force for thiskind of operation both for personnel and machinery. In detail, follow every particular prescription indicated inthis 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 movementof 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 alsothe air ventilation to the ventilation device (pressure reducer or snubber element) located in the left side ofthe 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 thebooster is not operational!Connect the pipe media to the lateral flanges blocking the tie rods operating in cross after having installed thering joint gaskets.WARNING: Make sure that INLET / OUTLET flow direction indications are respected to grant the correctworking of the system!WARNING: use only filtered process fluid not to damage the System Booster (3µ grade min. suggested).

Short Instructions

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-UP1. 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.

SHUTDOWN1. 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).
