Overview
PX Series pumps distribute chemicals through PTFE and PFA fluid paths. They are capable of up to 100°C (212°F) and offer air supply pressures up to 7 Bar (100 psi). The pumps operate with a solenoid valve and proximity switches, running continuously throughout their two-year warranty. The pumps are available in three models, PX30, PX60, and PX120, which are capable of maximum flow rates of 30, 60 and 120 lpm, respectively.
While White Knight continues to offer and support PX Series pumps, we recommend users consider PXA Series pumps, which provide better performance, increased flow rates, higher pressure capabilities, improved reliability, extended pump life and warranty periods, as well as shorter lead times. See comparisons below.
Features & Benefits
- PTFE and PFA liquid path

- No elastomer O-rings, no leaks, never retorque
- No lubrication in shift mechanisms
- No electric motors, which generate heat
- Various liquid connection options
- Easily replaces competitive products using proximity sensors
- Safe, leak-free operation due to no-metal design
- Polypropylene heads, stainless steel proximity targets
- Minimal parts for durable design
- Class 100 cleanroom assembly, testing, and packaging
- Easy to install and service
- Proven reliable to 400, 300, or 200 million+ cycles for the PX30, PX60, PX120, respectively
- No preventative maintenance during two-year warranty
Operation
PX Series pumps operate with proximity switches and solenoid valve that optimize stroke timing by shifting the bellows quickly and efficiently to increase durability.

*May vary depending on configuration. Suction lift diminishes over time. Recommended installation level less than 3 ft above source.
**dB Level at 60 psi 50 CPM (top) and 60 psi maximum CPM (bottom). Sound Levels measured in accordance with ISO9614-2:1997.
***Dry-run capable PXASD030 and PXASD060 pumps require flooded suction and may have a reduced warranty unless prior arrangements are made with White Knight. Contact White Knight for details.
