Introduction to Liquid Filling Machine Pump Types and Applications

Liquid filling machines are essential in modern packaging lines, with the liquid transfer pump being a key component. ZONESUN offers a variety of pump types to accommodate different liquid properties and production requirements:
1.Diaphragm Pump
Working Principle: Utilizes reciprocating diaphragm motion to transfer liquid.
Features: Resistant to chemicals, leak-proof, suitable for liquids with particles or corrosive properties.
Applications: Pesticides, cleaning solutions, acidic or alkaline fluids.
2.Peristaltic Pump
Working Principle: Moves liquid by compressing flexible tubing with rotating rollers.
Features: High precision, easy to clean, prevents cross-contamination.
Applications: Pharmaceutical, biotechnology, eye drops, laboratory use.
3.Gear Pump
Working Principle: Uses two meshing gears to transfer liquid through rotation.
Features: Stable output, ideal for medium to low-viscosity liquids.
Applications: Oils, inks, waxes, resins.
4.Magnetic Pump
Working Principle: Driven by magnetic coupling, fully sealed.
Features: No leakage, corrosion-resistant.
Applications: High-purity chemicals, electronic materials, purified water.
5.Piston Pump
Working Principle: Reciprocating piston motion for suction and discharge of liquid.
Features: High accuracy, handles viscous materials.
Applications: Honey, sauce, lotion, creams, toothpaste.
6.Rotor/Lobe Pump
Working Principle: Rotating lobes transfer liquids with minimal shear.
Features: Gentle handling, suitable for thick or particle-containing liquids.
Applications: Jam, peanut butter, dairy, shampoo.
7.Vacuum Suction (Anti-drip) Pump
Working Principle: Creates vacuum suction after filling to prevent dripping.
Features: Clean filling, maintains a drip-free workspace.
Applications: Food, cosmetics, pharmaceuticals.
