Q1｜What tubing size is required to achieve the full 45 L/min flow rate?
To reach the rated 45 L/min, the pump should be paired with 8×6 mm tubing.
Using smaller internal diameters restricts airflow and reduces overall system performance. For long piping routes, increase tube diameter or shorten tube length to minimize pressure loss.
Q2｜Can this micro pump handle corrosive or special gas media?
Yes — the BD-05T1045L supports multiple diaphragm/valve options:
EPDM (standard): polar gases such as alcohols and aldehydes
FKM: hydrocarbons, aromatics, solvent vapors
PTFE: strong acids/bases, highly reactive or high-purity gases
For complex gas mixtures, providing an MSDS helps ensure accurate material compatibility.
Q3｜How should the four head diaphragm pump be cooled during continuous operation?
The high-end brushed motor is designed for reliable performance at 0–45 ℃. For high-load or continuous-duty operation:
Keep ≥20 mm clearance around the pump for natural convection cooling
Use a metal baseplate to dissipate heat
Avoid sealing the pump in an airtight enclosure
Proper heat management prolongs diaphragm and motor lifespan.
Q4｜Can the BD-05T1045L work with humid or condensate-rich gases?
The pump is suitable for low-humidity gases. For systems with condensation:
Install a condensate trap or moisture separator
Add a 5 μm inlet filter
Prevent large temperature differences that cause internal condensation
Continuous moisture or water droplets can reduce diaphragm longevity.
Q5｜Can the mini pump be used for both vacuum and positive pressure?
Yes — the BD-05T1045L supports:
Vacuum up to –99 kPa
Pressure up to 2 bar
For dual-mode systems, use solenoid valves and safety relief valves to prevent overpressure and ensure safe operation.
