Installation & Wiring Guide – BD-05T1040LBL 

The BD-05T1040LBL series uses a 7-wire BLDC control interface, allowing precise speed control, PWM regulation, and FG feedback for system monitoring. This wiring structure provides OEM engineers with full flexibility in designing stable, controllable high-flow vacuum/pressure systems.

Power Supply Wiring

These two wires supply power to the BLDC motor driver:

  • Thick Red – Power +
    DC power positive input

  • Thick Black – Power –
    DC power negative input

Ensure your power source matches the required voltage (12 V or 24 V DC) and can support the motor’s peak current.

Control Signal Wiring

These wires are used for speed control, system monitoring, and reference voltage.

  • Yellow – SP (Analog Speed Control Input)
    Accepts analog voltage input for proportional speed regulation.

  • Thin Black – GND (Signal Ground)
    Common ground reference for SP, PWM, and FG signals.

  • White – PWM (PWM Speed Control Input)
    Supports 1 kHz–10 kHz PWM input; motor begins rotating when the duty cycle exceeds 10%.

  • Blue – FG (Speed Feedback Output)
    Provides square-wave feedback; a 4-pole BLDC motor outputs 12 pulses per revolution, enabling closed-loop monitoring.

  • Thin Red – 5V Output
    5 V reference output for an external potentiometer (VR) speed control circuit.

Speed Control Options

The pump supports two control methods:

  • Analog speed control (VR / Potentiometer): 1 kΩ–30 kΩ

  • PWM speed control: 1 kHz–10 kHz, duty cycle >10% for startup

Both control modes allow precise airflow and vacuum adjustment to match system requirements.

📌 Technical Insights & FAQ

Q1|What tubing size is required to achieve the full 45 L/min flow rate?

To reach the rated 40 L/min, the pump must be paired with 10×8 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 pump handle corrosive or special gas media?

Yes — the BD-05T1040LBL 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 pump be cooled during continuous operation?

The brushless motor is designed for reliable performance from –10 to 45 ℃.
For high-load or continuous-duty operation:

  • Keep ≥20 mm clearance around the pump for convection cooling
  • Use a metal baseplate to dissipate heat
  • Avoid sealing the pump in an airtight enclosure
    Proper heat management extends diaphragm and motor lifespan.

Q4|Can the BD-05T1040LBL work with humid or condensate-rich gases?

It is suitable for low-humidity gases. For systems containing condensation:

  • Install a condensate trap or moisture separator
  • Add a 5 μm inlet filter
  • Prevent temperature differences that cause internal condensation
    Water droplets or continuous moisture impacts reduce diaphragm longevity.

Q5|Can the pump be used for both vacuum and positive pressure?

Yes — it supports:

  • Vacuum up to –85 kPa
  • Pressure up to 1 bar
    For dual-mode systems, use solenoid valves and safety relief valves to prevent pressure overload.
