The BD-05TR12L uses a brushless DC motor with a 4-wire configuration, enabling precise speed control and real-time operating feedback. The wiring definition is as follows:
Red (VCC): DC power positive (+)
Black (GND): DC power negative (–)
Blue (SP): Speed control input (PWM or analog voltage, depending on system design)
Yellow (FG): Speed feedback signal (tachometer output for RPM monitoring)
This 4-wire BLDC architecture provides more stable operation, flexible speed adjustment, and accurate monitoring compared with traditional 2-wire brushed motors. When paired with a compatible controller, it allows straightforward integration into compact OEM equipment without complex external drive circuitry.

Q1｜What defines the oil-free advantage of a piston pump in OEM systems?
Oil-free piston pumps eliminate the risk of lubricant contamination within the gas path, which is critical for systems sensitive to particles, vapor residues, or maintenance intervals. This design improves system cleanliness, reduces downstream component fouling, and supports long-term stable operation without routine servicing.
Q2｜How does a dual-head parallel structure improve system efficiency?
In a parallel piston configuration, both pistons operate simultaneously, increasing volumetric flow per cycle without increasing stroke frequency. This improves flow stability, reduces pulsation, and allows higher airflow output while maintaining compact dimensions and moderate motor loading.
Q3｜What integration factors affect long-term stability in oil-free piston pumps?
Key factors include airflow resistance, thermal dissipation, and mechanical mounting. Minimizing inlet and outlet restriction, ensuring sufficient ventilation, and using rigid mounting surfaces help maintain stable piston motion and prevent performance degradation over extended operation.
Q4｜How should pressure and vacuum modes be managed in system design?
Although the pump supports both pressure and vacuum generation, frequent rapid switching between modes increases mechanical stress. For optimal durability, system designs should avoid abrupt mode transitions and use valves or buffers to stabilize operating conditions.
Q5｜What distinguishes oil-free piston pumps from diaphragm pumps in high-flow designs?
Oil-free piston pumps typically provide higher flow density and better pressure continuity in compact layouts. Their direct compression mechanism supports higher volumetric efficiency, making them well-suited for applications where airflow consistency and compact integration are critical.
