Beschreibung
Double diaphragm pump 1/4'', PVDF, PTFE is an air-operated double diaphragm pump intended for viscous, corrosive and abrasive liquids. The plastic design is appropriate for small-volume transfer, laboratory applications and occasional dispensing. Suction and pressure ports are configured as 1/4'' internal connections, and solid particles up to 3 mm in diameter can be pumped. Minimum start-up air pressure is 2 bar and maximum operating air pressure is 8 bar. From manufacturer Bürkle, the pump provides high hydraulic performance, a maintenance-optimised layout and easy installation. Operation remains blockage-free, absolutely oil-free and self-priming even under dry conditions. Typical applications include chemical circulation and feed, liquids containing solid particles such as paints and coatings, and electroplating baths. Housing, diaphragms, valve balls and seals are available in selected material combinations, enabling the PVDF/PTFE configuration to serve chemically demanding laboratory and light industrial transfer tasks with reliable dry-run behaviour.

Questions about Double diaphragm pump 1/4'', PVDF, PTFE
What is this article?
Double diaphragm pump 1/4'', PVDF, PTFE 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.
