Description
Aeration/gassing pump with manual speed control is a compact diaphragm unit designed for laboratory aeration, filtration and liquid aspiration via vacuum. The pump delivers a flow rate of 0,4 – 0,40 m³/h and reaches an ultimate vacuum below 130 mbar, making it suitable for gentle gas transfer and sample handling. An integrated speed regulator allows precise adjustment of performance, while the PTFE-coated membrane resists aggressive and corrosive gases and vapours. Hose nozzles of 6 mm diameter together with a combined silencer and intake filter support clean, quiet operation. The unit is supplied with a 24 V power supply featuring interchangeable plugs for flexible laboratory use. Manufactured by Landgraf HLL, this aeration and gassing pump is compatible with systems such as MyFerm and selected flame photometers, and optional accessories including fine-control valves with vacuum or pressure gauges further extend its application range. The robust construction and chemical-resistant membrane make it a practical choice for continuous or intermittent gas handling, vacuum-assisted filtration and controlled aeration tasks in research and routine laboratory workflows.

Questions about Aeration/gassing pump
What is this article?
Aeration/gassing pump is the article on this page. Luminix Health distributes Landgraf HLL for laboratory use. It sits in Pumps (other) & accessories, inside Pumps, vacuum & evaporation, in Lab instruments.
These are the pumps and fittings that are not a vacuum pump, a peristaltic pump or a drum pump. Flow, pressure and chemical compatibility of the wetted parts remain the three questions.
A vacuum pump lowers the pressure above a liquid so it boils at a lower temperature. That is the point of a rotary evaporator: solvent leaves a sample without cooking it. A diaphragm pump or a rotary-vane pump is chosen by the vacuum it reaches and by whether solvent vapour will destroy it. A peristaltic pump moves liquid by squeezing a tube, so the liquid touches only the tube. A barrel pump transfers a larger volume from a drum. The glassware on the evaporator is indexed under ISO laboratory glassware. Solvent identity is on PubChem.
