Overview of BD-05TVB DC Diaphragm Pump

Miniature diaphragm pumps use a DC motor to drive a flexible diaphragm via an eccentric cam. As the diaphragm moves, it draws in and expels gas in an oil-free, controlled manner to generate vacuum or pressure. The BD-05TVB’s dual-head design allows parallel operation for higher flow or series operation for higher vacuum—offering engineers flexible performance options.

The BODENFLO BD-05TVB is a compact dual-head mini diaphragm pump driven by a brushless DC motor, offering stable flow, extended lifespan, and low noise operation. Engineered for high-vacuum, moderate flow, and low power consumption, it's an ideal solution for applications requiring precision performance in tight spaces.

Whether configured in parallel mode for up to 7.2 L/min at -70 kPa, or series mode for reaching -90 kPa vacuum at 4.6 L/min, this pump supports critical functions in medical rehabilitation, negative pressure wound therapy, vacuum sampling, and laboratory devices.

Frequently Asked Questions (FAQ)

Q1: What are the advantages of the BD-05TVB diaphragm pump?
The BD-05TVB is a brushless, long-life version with dual-head design, making it a reliable replacement for popular EU/US models. Brushless options include the dual-head BD-05TVB and single-head BD-05TVB-S. Brushed versions are also available: BD-05T057.2L (dual-head) and BD-05T054.6L (single-head).

Q2: Can the BD-05TVB run continuously?
Yes. It fully supports 24/7 continuous operation, making it ideal for medical equipment and environmental monitoring applications.

Q3: Is this pump designed for air or liquid?
This is a diaphragm air pump, capable of generating vacuum, pressure, and gas circulation. It can handle small amounts of moisture but is not suitable for direct liquid transfer. For liquid circulation, we recommend our dedicated micro liquid pump series.

Q4: What is the lead time for samples?
Sample orders are usually shipped within 1–3 days via international couriers such as DHL or FedEx. Bulk orders can be shipped by sea, air, or railway depending on customer preference.

Q5: What certifications does BODENFLO provide?
Our pumps comply with CE and RoHS standards, and our factory is ISO9001 certified. We can provide complete inspection reports and conformity certificates to meet international regulatory requirements.
