Q2: What is the pump’s flow curve performance under vacuum?
At atmospheric pressure, the pump delivers ~40 L/min. At –80 kPa, flow is maintained at ~1.5 L/min, ensuring stable sampling under high vacuum conditions.
Q3: Can the pump operate continuously at maximum vacuum?
Yes. The BD-05T1040LB is designed for continuous duty, with optimized heat dissipation via the aluminum body and imported bearings for long-term stability.
Q4: How is leakage minimized in this model?
It uses a precision sealing system with PPS pump head, high-grade elastomers (EPDM, optional FKM/PTFE), and CNC-machined aluminum housing to achieve excellent gas tightness.
Q5: What kind of vibration and noise levels can be expected?
The balance-optimized design and brushless motor reduce vibration transmission, keeping noise typically <65 dB under rated load.
Q6: What customization options are available for OEM projects?
OEMs can select diaphragm/valve materials (EPDM, FKM, PTFE), specify connector types and cable lengths, and request private labeling or dual-head configurations.
Q7: Is the BD-05T1040LB suitable for both vacuum and pressure applications?
Yes. It supports vacuum down to –85 kPa and can generate pressure up to 1 bar, making it versatile for suction and compression tasks.
Q8: What protections are built into the pump design?
The pump features IP20 housing, thermal management through aluminum body conduction, and brushless motor electronics with overload protection for safe long-term operation.
