Beschreibung
Double diaphragm pump 1/4'', PP, NBR is a compressed-air-operated unit for transferring viscous, corrosive and abrasive liquids in small quantities. The plastic construction suits laboratory use and occasional filling tasks. Suction and pressure ports are 1/4'' internal thread; solid particles up to 3 mm diameter can be conveyed. Start-up requires a minimum air pressure of 2 bar, with a maximum operating air pressure of 8 bar. The design delivers high hydraulic performance, blockage-free running, oil-free operation and self-priming capability even when dry, with a maintenance-oriented layout for simple installation. Typical applications include chemical circulation and supply, liquids containing solid particles such as paints and coatings, and electroplating baths. Housing, diaphragms, valve balls and seals are available in different material combinations; this variant is specified as PP with NBR. Offered by manufacturer Bürkle as a compact laboratory-scale diaphragm pump, it supports controlled transfer where compressed air is preferred over electric drive. Net weight is 2,65 kg. Pack size is one piece.

Questions about Double diaphragm pump 1/4'', PP, NBR
What is this article?
Double diaphragm pump 1/4'', PP, NBR is the article on this page. Luminix Health distributes Bürkle for laboratory use. It sits in Vacuum pumps, inside Pumps, vacuum & evaporation, in Präzisionsinstrumente.
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.
