Certificate No.:
IECEx FMG 16.0012X
Date of issue:
2020-04-02
EQUIPMENT:
Equipment and systems covered by this Certificate are as follows:
The P1.3 sample gas pump carry gases from various processes to analyzers. The gas circuit typically has additional analysis components
such as sample gas probe, filter, flow meter, cooler, etc. The sample gas pump P1.3 consists of the main components the pump head and
motor. An eccentric converts the rotation of the motor into an up and down motion using a connecting rod, thus producing the pump
mechanism. Inside the so-called pump body, above the bellows, which facilitates the pump motion, are inlet and outlet valves. The user
connects the gas circuits to the sample gas pump through screw-in connections.
The P1.3 sample gas pumps are available as 12Vdc, 24Vdc, 115Vac, 60Hz or 230Vac, 50Hz. The 115Vac and 230Vac sample gas pumps
have internal self resetting thermal protection built into the motor.
SPECIFIC CONDITIONS OF USE: YES as shown below:
1. The installer shall provide transient over-voltage protection of the supply connections at a voltage not to exceed 140% of the voltage
rating of the pump.
2. The pump shall be mounted in an enclosure providing a minimum degree of protection of IP54 in accordance with IEC/EN 60079-15,
and shall be installed within a tool-secured enclosure which meets the requirements of IEC/EN 60079-0 and IEC/EN 60079-15.
3. To maintain a T4 to T3 temperature class care shall be taken to ensure the enclosure temperature does not exceed 50°C.
4. Temperature class are defined by the following table:
