How Does the RS-4 Handle Different Liquid Viscosities Accurately?

Unified Flex RS-4 rotary filling machine maintaining accurate liquid filling across different viscosities in a high-speed production environment for medical and pharmaceutical packaging
Switching from thin juices to thick sauces or lotions throws most fillers off balance — drifting weights, product giveaway, and constant tweaks follow. The RS-4 Spouted Pouch Filler & Capper from Unified Flex handles this range with servo-controlled pistons that adjust stroke, speed, and motion to match each liquid’s flow. Four independent filling heads deliver up to 80 pouches per minute while maintaining tight volumetric accuracy for beverages, shampoos, detergents, and even particulate-laden products. Precision rotary indexing, “No Pouch – No Fill” logic, and quick tooling changes keep waste low and OEE high across multiple SKUs on one machine.
