The BD-05T30KH is a compact, oil-free double-head diaphragm pump designed to deliver higher airflow within a limited installation space. Driven by a brushless DC motor, each diaphragm reciprocates to alternately generate suction and discharge, forming a stable gas transfer cycle without lubrication or mechanical contact with the medium.
By combining two pump heads in a single structure, the platform supports parallel operation for increased flow capacity or series configuration for enhanced vacuum (BD-05T30K), allowing OEMs to scale performance without redesigning the pump architecture. This design ensures controlled pulsation, low leakage, and stable output under continuous operating conditions.

Q1｜How does the dual-head diaphragm pump enhance performance?
The two heads allow parallel or series operation, increasing total airflow or vacuum. Proper head synchronization ensures balanced suction and stable pressure in compact systems.
Q2｜What are critical design considerations for diaphragm selection?
Diaphragm material affects chemical compatibility, elasticity, and fatigue life. KEE/EPDM provides excellent corrosion resistance and mechanical stability for continuous operation.
Q3｜How should this pump be integrated into compact OEM systems?
Ensure thermal dissipation, elastic mounting for vibration isolation, and accessible tubing paths. Minimizing dead volume and optimizing tube diameter improves flow and vacuum efficiency.
Q4｜What benefits does the brushless motor provide?
BLDC motors offer high torque stability, extended service life, and minimal electrical and acoustic noise, critical for continuous industrial or analytical applications.
Q5｜Can the pump be configured for variable operating modes?
Yes. By adjusting motor control, diaphragm choice, and flow routing, the pump can operate under vacuum, positive pressure, intermittent duty, or speed-controlled conditions for different OEM requirements.
