- Beverages: Juice, wine, and other drinks.
- Chemicals: Low to high viscous products, can handle corrosive and abrasive fluids
Advantages
- Continuous flow pumps: good for dosing large volume containers
- Durability: Handles abrasive and corrosive fluids well.
- Versatile: Accommodates a wide range of viscosities.
- Easy setup: only one line of compressed air is required.
Disadvantages
- Noisy and compressed air consumption. Not good for clean room applications.
- Pulsating Flow: May need pulsation dampeners for smooth operation.
Piston pump
A piston pump is a type of positive displacement pump that uses a piston to move fluids, offering high precision and pressure capability.
Key features:
- Positive Displacement: Traps and displaces fluid.
- High Pressure: Effective for high-pressure applications.
- Precision: Accurate dosing and control.
- Servo-Controlled: Reliable, self-priming, and operates directly from IBCs or other product vessels.
- Manual Cleaning: Scaldopack pumps allow tool-free manual disassembly for daily cleaning and changing of seals.
Applications
- Food: Syrups, sauces, juices, milk, yogurt, broths, tea, etc.
- Pharmaceuticals: Sterile fluids.
- Chemicals: Low to high viscous products
Advantages
- High Pressure: Handles high viscous products and can generate high dosing pressures.
- Precise Control: Accurate dosing.
- Self-Priming: No buffer hopper needed.
- Easy Cleaning: Manual disassembly without tools.
Disadvantages
- Slow process: If high speed is required, two pumps are advised. It is slow to it non contiguous functioning (suction cycle, dosing cycle)
- Continuous flow: Large volume dosing renders pumps heavy and difficult to handle.
- Maintenance: For high level of sanitary application daily disabling and cleaning is required.
