Description
CRVpro 4 rotary vane vacuum pump delivers a maximum pumping speed of 63 l/min and reaches an ultimate total pressure of 2×10⁻³ mbar according to DIN 28432. The single-phase motor operates on 220–240 V / 50 Hz or 230 V / 60 Hz, draws 370 W and carries IP54 protection. Net weight is 21 kg (gross 26 kg). The pump is supplied with both EU (CEE 7/4) and UK (BS 1363) line cords and carries CE, cUL and IE2 markings. Designed by manufacturer WELCH for continuous laboratory and industrial vacuum applications, the CRVpro 4 provides reliable two-stage rotary-vane performance for freeze-drying, vacuum ovens, filtration, degassing and general process vacuum duties. Compact construction and robust sealing make it suitable for demanding daily use in research, quality-control and production environments where consistent ultimate vacuum and moderate free-air displacement are required. Supplied as a complete single unit ready for immediate installation.

What is this article?
CRVpro 4, 63l/min, 2x10-3mbar, 220-240V / 50Hz; 230V / 60Hz; 1 phase motor with 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.
