The BD-05TR32LB is a compact double-head swing piston pump built for systems that demand high pressure density and deep vacuum capability within a limited installation space.
Each piston alternately generates negative pressure during the intake stroke and positive pressure during the compression stroke, enabling efficient gas evacuation and compression within a rigid mechanical structure.
By combining two piston heads, the pump supports parallel operation to increase airflow output or series operation to achieve deeper vacuum levels. This flexible architecture allows OEM engineers to configure pressure, vacuum, and flow characteristics according to specific system requirements, while maintaining stable output and controlled pulsation under load.

Q1｜How does a double-head swing piston design improve system flexibility?
A dual-head configuration allows the pump to operate in either parallel or series mode. Parallel operation prioritizes higher airflow, while series operation increases achievable vacuum depth. This gives OEMs flexibility to optimize one hardware platform for multiple performance targets without redesigning the pump core.
Q2｜What makes swing piston pumps suitable for high pressure density in compact systems?
Swing piston pumps rely on rigid mechanical compression rather than elastic deformation. This enables higher compression ratios, faster pressure build-up, and better dimensional stability under load, making them well suited for compact systems where pressure performance is critical.
Q3｜How should thermal management be addressed in high-load applications?
High pressure and deep vacuum operation increase thermal load on the motor and piston assembly. System designs should incorporate forced airflow, sufficient ventilation clearance, or auxiliary cooling to maintain stable temperature and protect long-term reliability.
Q4｜What integration factors most affect long-term performance?
Key factors include minimizing back pressure, using rigid mounting surfaces to control vibration transmission, and selecting appropriate tubing and fittings rated above the system’s maximum pressure. Proper mechanical integration significantly reduces stress on piston and valve components.
Q5｜When is a double-head piston pump preferred over single-head solutions?
Double-head piston pumps are ideal when a system requires both high flow and deep vacuum options, or when different operating modes are needed across product variants. This architecture allows one pump platform to support multiple performance profiles with minimal system redesign.
