Le corps central de la pompe abrite la part d’alimentation en air, souvent contrôlée par une valve pneumatique interne qui régule l’entrée et la sortie de l’air. Cette valve dirige l’air comprimé vers l’une des deux chambres, poussant ainsi le diaphragme de cette chambre vers l’avant. Ce mouvement de compression pousse le fluide hors de la chambre correspondante, à travers la sortie, tout en créant une dépression dans l’autre chambre.
When hydrophobic membranes occur into connection with h2o, floor stress forces act to repel the water in the pores. Drinking water won't enter the pores as well as the membranes will work as a barrier to h2o circulation, unless the h2o is applied at pressures higher as opposed to membrane’s h2o entry pressure. Small floor pressure fluids, including alcohols, can spontaneously enter and fill the pores of hydrophobic membranes.
Assurez-vous ainsi que les vannes et le siège de valve ne soient pas obstrués par des débris, ce qui pourrait affecter le passage des fluides dans et hors de la pompe et diminuer son efficacité.

The capture of samples occurs with a flat, glass-like sleek floor with a fair distribution of particles captured on one airplane, simplifying microscopic and SEM evaluation of samples captured over the surface with the membrane.
Outre leur design and style compact, les pompes à membrane ont toute une gamme de caractéristiques uniques qui les distinguent des autres styles de pompes, faisant d’elles un choix populaire pour une vaste gamme d’apps industrielles.
PCTE membrane filters may also be dissolved with toluene and perhaps with other identical aromatic hydrocarbon solvents.
Technologie LEAP® : réduit la pression d’air nécessaire et minimise les pertes internes et la friction.
Le retour sur investissement de ce form de pompe peut être atteint en quelques mois seulement, en fonction de votre application.
Hydrophobic membrane filters are occasionally used with h2o or aqueous remedies; and, in these applications, they must first be prewet which has a minimal surface rigidity, h2o miscible fluid previous to use.
Preliminary conclusions involving five small children assessed following six months showed the cure was Protected and triggered improved respiration skills.
Sterlitech Observe Etch filter membranes are manufactured and produced less than class one hundred situation for the duration of critical producing techniques. Thus, the membrane is freed from contaminants and pyrogens.
Nominal pore measurement rankings differ from manufacturer to producer and, For that reason, are usually not essentially equal. Filters from distinctive manufactures with identical nominal pore pompe pneumatique à double membrane dimensions scores might not actually show related retention characteristics.
Both of those forms of track-etch membranes can be dissolved with elevated temperature sodium hydroxide remedies.
