Purpose & User
The HNZXIB DP-01 is an oil-free vacuum pump delivering 20L/min no-load flow at 220V for laboratory vacuum filtration, solvent purification and degassing tasks. Its PTFE-coated diaphragm prevents contamination, making it suitable for analytical work where clean media are essential. The compact unit includes a metal handle and built-in vacuum gauge for portable bench use.
Upgrade Path
This pump replaces oil-lubricated models that risk introducing hydrocarbons into filtered solvents or chromatographic samples. The jump is worth it when protocols demand oil-free operation, corrosion resistance or noise below 50db in shared lab spaces. It is not suited for applications requiring deeper vacuum than 0.08Mp negative pressure or positive pressure above 30Psi.
Sustained Operation
Rated at 60W, the pump maintains stable performance during extended filtration, distillation or rotary evaporator cycles without oil degradation. Low noise under load stays at 50db, and the PTFE coating resists chemical attack over repeated runs. Wooden-case packaging protects the unit during the 7-14 day transit window.

Questions about this item
What space and power supply does the DP-01 need to operate?
It runs on 220V 50 Hz mains, draws 60 W, and has a metal carry handle for portable bench-top placement.
How do I connect the pump for vacuum filtration and what step is often missed?
Fit the chosen filter membrane, attach tubing to the inlet, and check the built-in vacuum gauge to confirm negative pressure reaches at least 0.08 Mpa before starting.
What ongoing care does the oil-free DP-01 require?
No oil changes are needed; periodically clean the PTFE-coated diaphragm chamber and verify the gauge still reads 20 L/min no-load flow and noise stays around 50 dB.
