Fixed Sample Pump
Designed For Applications Needing Positive Pressure
This high-quality pump provides positive upstream pressure to push sample gas through an Analyzer. Its unique diaphragm can draw pressures from as low as 14” Hg without allowing more than 0.05 ppm of oxygen from diffusing into the system. This not only ensures that oxygen levels are not artificially elevated, but it still allows the sensor to continue operating at or near atmospheric pressure – a requirement for proper functioning of an electrochemical sensor. The unit utilizes a 12VDC brushless motor for long life and can endure over 20,000 hours of continuous operation. The Fixed Sample Pump has approval for Class 1, Div. II Group C,D environments and is suitable for a wide range of difficult applications.
