Overview
AT Series pumps were the world’s first metal-free PTFE and PFA pumps capable of distributing chemicals at up to 210°C (410°F) in constant or thermal cycling applications. The pumps perform safely and reliably running continuously throughout their one-year warranty. They offer air supply pressures up to 4 Bar (60 psi). The pumps are available in three models, AT50, AT100 and AT300HD, which are capable of maximum flow rates of 20, 40 and 110 lpm, respectively.
Features & Benefits
- Metal-free PTFE and PFA liquid path
- Leak-proof, machined design
- PTFE heads with Synchro-Thread™
- No elastomer O-rings, no leaks, never retorque
- No lubrication in shift mechanisms
- No electric motors, which generate heat
- Pneumatic Logic™ minimizes pulsation and vibration
- Various liquid connection options
- Safe, leak-free operation due to no-metal design
- Ceramic in air shuttle valve
- Minimal parts for durable design
- Class 100 cleanroom assembly, testing, and packaging
- Easy to install and service
- Proven reliable to 200 million+ cycles
- No preventative maintenance during one-year warranty
