Q1: What is the advantage of the dual-head BD-05T057.2L pump?
The dual-head design offers flexible performance:
Parallel mode: Delivers higher flow (up to 7.2 L/min at –70 kPa).
Series mode: Provides stronger vacuum (up to –90 kPa at 4.6 L/min).
This flexibility allows OEM engineers to adapt the pump to different application requirements.
Q2: Does this dual-head brushed pump have a brushless version?
Yes. We also offer the BD-05TVB dual-head brushless pump, which provides a longer service life (>10,000 hours), quieter operation, and greater efficiency—making it suitable for advanced medical, analytical, and high-end industrial applications.
Q3: Can this diaphragm pump handle liquids?
It can tolerate a small amount of moisture or water vapor, but it is not designed for direct liquid transfer. For water circulation or liquid handling applications, we recommend choosing from our dedicated micro liquid pump series.
Q4: What is the warranty period for this pump?
Our pumps come with a 1–2 year warranty, depending on the application and operating environment. Extended warranty options are available for OEM orders.
Q5: Where do you ship from, and what shipping methods are available?
All pumps are shipped directly from Shenzhen, China.
Samples: Shipped via international express couriers such as DHL, FedEx, or UPS for fast delivery.
Bulk orders: Typically shipped by sea, air, or railway freight, depending on customer preference and urgency.
