Swing Piston Gas Pump 5.5Lpm 8k Longlife Brushless dc air compressor BD-05TR5LB

Overview of BD-05TR5LB Swing Piston Gas Pump

The BD-05TR5LB is a compact swing piston gas pump designed for stable pressure output and reliable vacuum generation. Its reciprocating piston mechanism creates both positive pressure and negative pressure by compressing air on the forward stroke and drawing in air on the return stroke, enabling efficient, oil-free operation in a small form factor. Driven by a high-efficiency brushless motor, the pump delivers up to 5.5 L/min airflow, high pressure, and high vacuum with low noise, low vibration, and long service life.

Installation & Wiring Guide

The BD-05TR5LB uses a brushless DC motor with a 4-wire configuration, allowing precise speed control and real-time speed monitoring. The wiring definition is as follows:

Red (VCC): DC power positive (+)
Black (GND): DC power negative (–)
Blue (SP): Speed control input (PWM or voltage control depending on system design)
Yellow (FG): Speed feedback signal (tachometer output for RPM monitoring)

This 4-wire BLDC design enables more stable operation, flexible speed adjustment, and accurate feedback compared with traditional 2-wire brushed motors. It also supports easy integration into compact industrial and laboratory equipment, with no need for complex external drive circuitry when used with a compatible controller.

📌 Technical Insights & FAQ

Q1｜How does the swing piston mechanism affect airflow and system design?

The swing piston generates airflow through direct reciprocating compression, producing a stronger pressure curve and faster response than diaphragm pumps. Because of this higher impulse output, systems should incorporate vibration-absorbing mounts and flexible tubing to maintain stable airflow and pressure delivery.

Q2｜What considerations are important when selecting a power supply for the BD-05TR5LB?

A regulated DC power supply is essential for consistent performance of the brushless motor. Ensure sufficient current capacity, stable voltage under load, and low ripple to avoid speed fluctuations or reduced pressure output. For PWM speed control, verify that the controller frequency matches the pump’s BLDC driver requirements.

Q3｜How can noise be minimized when integrating the pump into compact equipment?

Noise reduction can be achieved by isolating the pump from the device chassis, reinforcing thin mounting surfaces, and using soft anti-vibration pads. Airborne noise can also be reduced by installing dedicated silencers on the inlet or outlet to smooth airflow pulses produced by the swing piston mechanism.

Q4｜What should be considered when operating the pump near its maximum pressure or vacuum?

When the pump operates above 1 bar, the motor and piston experience higher mechanical resistance, resulting in increased friction and heat generation. This has a direct impact on service life and allowable operating time. For applications requiring sustained high load, it is recommended to select a pump designed for higher pressure capability, maintain stable operating conditions, avoid rapid switching between vacuum and pressure modes, and ensure adequate heat dissipation around the pump housing to protect the internal components.

Q5｜How do I ensure long-term reliability in continuous-duty applications?

Stable long-term operation depends on maintaining clean, particle-free airflow and adequate cooling. Use appropriate inlet filtration, avoid exposure to corrosive liquids or condensate, and ensure open airflow paths around the pump. For fixed-speed applications, operating below maximum pressure enhances durability and reduces wear on the swing piston assembly.
