Applications of Miniature Motors and Gearboxes
in Chemical Dosing Systems

Peristaltic Pumps

Purpose: Deliver precise, repeatable volumes of chemicals or reagents.
Gearbox Role: Drives the roller mechanism slowly and consistently for controlled flow rates.
Benefit: Ensures accurate, pulsation-free dosing for analytical and research processes.

Automated Dispensing Systems

Purpose: Deliver small, programmable doses of liquids or gases with digital precision.
Gearbox Role: Supports high-resolution control and smooth torque delivery, often integrated with feedback sensors.
Benefit: Enables precise and repeatable motion in automated laboratory equipment.

Batch Dosing Equipment

Purpose: Dispense exact volumes of chemicals or ingredients for formulations and research processes.
Gearbox Role: Coordinates motion between pumps, valve actuators, and conveyance systems.
Benefit: Ensures synchronised, accurate fluid handling in laboratory workflows.
