PTFE Bellows Pump - PDBP

PTFE Bellows Pump -  PDBP

The PDBP Series PTFE bellows pump adopts a high‑purity clean structure design and is fully constructed of metal-free PTFE material. It delivers contamination‑free and corrosion resistant performance to ensure safe and reliable transfer of process media.
It is widely adopted in semiconductor, photovoltaic, LED, optoelectronics, panel and other industries, and is extensively applied in acid feed‑in systems and process systems.

Features

1. Zero metallic components on both external surfaces and internal wetted parts.
2. Oil free lubrication design eliminating potential contamination risks.
3. Non-contact, friction free interface between bellows and pump body for superior reliability.
4. Air-driven operation with no motor. Fully automatic operation upon compressed air supply; no risks of motor overheating or motor failure.
5. Simple structure for easy operation.
6. Robust and durable. Specially engineered PTFE bellows with maximum working pressure up to 7 bar.
7. 2-year product warranty; no preventive maintenance required within the warranty period.

Besides manufacturing our own PTFE bellows pumps, CJan Fluid also provides repair and spare part replacement service for White Knight and DINO bellows pumps.
