Description of Equipment:
The P1 sample gas pumps 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 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 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. The P1.3
sample gas pump is for hazardous locations.
