Q1: What makes the BD-05T053LH different from other gas sampling pumps?
The BD-05T053LH is specifically engineered for high-temperature gas sampling up to 150 ℃, a capability not available in most standard diaphragm pumps. Its corrosion-resistant construction ensures long-term reliability in CEMS and industrial analyzers.
Q2: How does the BD-05T053LH improve accuracy in gas analysis?
By maintaining a stable, low-pulsation flow under high heat, this pump reduces sampling fluctuations. This stability ensures more consistent results in VOC detection, emission monitoring, and laboratory instruments.
Q3: Why is the stainless steel pump head important?
The stainless steel head (304 standard, 316 optional) provides superior durability and chemical resistance, making it ideal for hot, reactive, or corrosive gases where plastic pump heads would degrade.
Q4: What kind of OEM support can BODENFLO provide?
We support OEMs with custom head materials, diaphragm selection, cabling, connectors, and branding. Engineering drawings and integration advice are also included to simplify system design.
Q5: How does the BD-05T053LH reduce total cost of ownership?
With its brushless motor (>8000 hours), maintenance-free design, and oil-free gas path, the pump minimizes downtime and eliminates the need for consumables—saving OEMs both time and operational costs.
