Överföring av vätskor: Direkt-vätskeöverföring vs. tryck-över-vätska-överföring
En pump suger vätska från en källa och släpper ut den i en behållare, vilket möjliggör ett exakt och jämnt flöde.
Benefits
- Fast, efficient transfer
- Smooth flow and easy installation
- Precise control of flow rates
- Some pumps offer chemical resistance, self-priming, dry-running safety and long service life
Applications : Ink transfer, medical diagnostics, cleaning agents.
Challenges
- Risk of clogging with fibrous media
- Wear from abrasive fluids
- Hygiene problems (difficult to sterilize)
- Possible pulsation
Diaphragm pumps for direct transfer
Diaphragm pumps excel at direct transfer of liquids:
- Precise flow, up to 16 bar
- Self-priming and dry-running safe
- Adaptable to chemical applications.
For low pulsation , KNF Smooth Flow technology is used , i.e. integrated dampers or phase-shifted membranes (e.g. FP 1.7 Smooth Flow) to reduce vibrations, noise and pressure peaks.
