High-Precision Dosing Solutions for Viscous & Non-Newtonian Fluids.
Industry-Standard Dosing Technology for Viscous & Aggressive Products.
Our closed-loop servo-piston systems deliver pharmaceutical-grade accuracy (±0.30%) across extreme viscosity ranges (1-100,000 cP) through:
Zero Dead-Volume Design: Sanitary cylinders with polished internals
Coaxial Anti-Drip Nozzles: Spring-loaded retraction with product cut-off
Smart Stroke Control: Adaptive algorithms for shear-sensitive products
Quick-Change Tooling: <10 min format conversions
Precision volumetric displacement without product degradation.
Our modular piston-dosing systems deliver unmatched versatility across extreme viscosity ranges (1-100,000 cP) and chemical aggressiveness through:
Material Flexibility: Simple seal/swapping enables compatibility with acids, solvents, and food products
Precision Mechanics: ±0.3% accuracy independent of product density changes
Robust Construction: Hardened cylinders for abrasive slurries
Proven Reliability: Field-tested in harsh industrial environments
