Description
Vacuum/pressure pump 2522 is a laboratory pump that combines vacuum and pressure capability in one unit, with a free-air capacity of 18 l/min, a vacuum rating of 133 mbar and a pressure rating of 7,9 bar. Electrical supply is 230 V, 50 Hz, single phase, and the configuration includes a Schuko connection; manufacturer data also reference UK plug leads for broader mains compatibility. Net weight is 5,3 kg, giving a manageable footprint for bench or equipment-cart placement in general laboratory service. This vacuum/pressure pump 2522 from manufacturer WELCH is intended for laboratory material applications where both reduced pressure and positive pressure are needed for filtration, transfer or process support tasks. Supplied as a single-piece unit, it presents clearly defined performance figures so engineers and laboratory managers can match flow, vacuum and pressure to their setup. Country of origin is the USA. The stated dual vacuum/pressure envelope and mains specification support straightforward integration into standard 230 V laboratory environments.

Questions about Vacuum/Pressure pump 2522, 18l/min, 133mbar, 7.9bar, 230V 50Hz, 1 Ph with Schuko
What is this article?
Vacuum/Pressure pump 2522, 18l/min, 133mbar, 7.9bar, 230V 50Hz, 1 Ph with Schuko is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Vacuum pumps, inside Pumps, vacuum & evaporation, in Lab instruments.
A laboratory vacuum pump lowers pressure for filtration or evaporation. A diaphragm pump tolerates solvent vapour better than an oil-sealed rotary vane pump, and it reaches a milder vacuum. The ultimate vacuum and the flow, and whether the wetted path survives the solvent, are the choices.
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.
