Typical applications

Fragrance & Colorant Dosing

Fragrance and colorant dosing is critical for maintaining brand consistency and sensory appeal. These components are often high-value and require precise micro-dosing to avoid costly waste. The process must handle a wide range of viscosities and ensure repeatability across batches. Hygienic design is essential to prevent cross-contamination between scents and shades. Quick changeovers are vital for multi-product lines, and equipment should integrate seamlessly with automated batching systems. Temperature stability and low shear are also important to preserve delicate aromatic compounds.

Relevant products:

• Valveless Piston Pumps: Provide ultra-precise dosing with ±1% accuracy and repeatability under 0.5%. Their ceramic wetted path resists wear and chemical attack, making them ideal for fragrance oils and pigments

  Key benefits:

  • Accuracy independent of viscosity
  • Minimal maintenance (one moving part)
  • Long service life for abrasive pigments
• Peristaltic Pumps: Perfect for quick changeovers and hygienic operation. Tubing acts as the fluid path, reducing cleaning time and allergen risk.

  Key benefits:

  • Disposable tubing for zero cross-contamination
  • Low shear for delicate fragrances
  • Scalable from lab to production

• Micro Gear Pumps: Deliver smooth, pulse-free flow for continuous dosing of colorants in automated lines.

  Key benefits:

  • Compact design for OEM integration
  • High repeatability for continuous dosing
  • Handles low to medium viscosity fluids

Active Ingredient Addition

Adding actives such as vitamins, botanical extracts, and preservatives requires precision and traceability. These ingredients often have strict dosage limits and can be sensitive to shear and temperature. Equipment must ensure accurate delivery while maintaining product stability. Integration with recipe management systems is key for compliance and batch reporting. Cleanability and CIP compatibility are essential for allergen control and GMP adherence.

Relevant products:

• Syringe Pumps: Ideal for R&D and pilot-scale dosing of actives with high accuracy.

• Key benefits:

  • High precision for micro-volume dosing
  • Programmable for complex sequences
  • Perfect for formulation development
• Valveless Piston Pumps: For production-scale addition with repeatable performance.

• Key benefits:

  • Handles viscous extracts without drift
  • Simple wetted path for easy cleaning
• Coriolis Flow Meters: Provide mass flow and density measurement for critical ingredients

• Key benefits:

  • Direct mass flow measurement
  • Density and temperature compensation
  • Excellent for recipe control and audit trails

Creams, Lotions & Gel Transfer

Transferring viscous emulsions like creams and gels requires pumps that can handle high viscosity without compromising texture. Low shear is critical to maintain product structure and prevent phase separation. Equipment should support hygienic design and CIP/SIP processes. Pressure stability is important for filling accuracy and avoiding aeration. Scalability from pilot to full production ensures flexibility for growing brands.

Relevant products:

• Peristaltic Pumps: Low shear transfer with disposable tubing for hygienic operation

• Key benefits:

  • Gentle handling of shear-sensitive creams
  • Quick tubing swaps for allergen control
• Pressure Regulators: Maintain stable pressure on fillers to prevent dripping and foaming.

• Key benefits:

  • Smooth pressure control for consistent fills
  • Hygienic design for CIP compatibility
• Temperature Transmitters: Monitor heat-sensitive emulsions during transfer.

• Key benefits:

  • Accurate monitoring for wax phase control
  • Easy integration with PLC systems
