Applications of Miniature Motors and Gearboxes in Dosing Systems

Precision Dosing Pumps

Application: Accurate dispensing of fluids such as chemicals, pharmaceuticals, or food ingredients.
Gearbox Role:
- Reduces motor speed and increases torque for smooth, consistent delivery.
- Ensures repeatable dosing volumes and prevents overshoot.
Examples: Peristaltic pumps, diaphragm dosing pumps.

Flow Control Valves

Application: Constant airflow, pressure accuracy, very low noise, compact design, long-term durability.
Gearbox Role:
- Drives actuators for valve positioning and modulation.
- Provides torque for smooth control of large or high-pressure valves.
Examples: Patient comfort, compliance, and reliable nightly therapy.

Chemical Injection Systems

Application: Controlled injection of additives or treatment chemicals into pipelines or reactors.
Gearbox Role:
- Provides low-speed, high-torque operation for metering pumps.
- Supports continuous or batch dosing with high precision.
Examples: Corrosion inhibitors, pH control chemicals.

Mixing and Blending

Application: Homogenising or blending fluids and additives in controlled quantities.
Gearbox Role:
- Drives agitators or mixers at controlled speeds.
- Prevents over-mixing or shear damage to sensitive materials.
Examples: Paints, polymers, pharmaceuticals.

Filling Machines

Application: Automated filling of containers or bottles with measured liquid volumes.
Gearbox Role:
- Controls rotary or linear actuation for piston or gear pumps.
- Provides precise motion for accurate fill levels and consistency.
Examples: Beverage bottling, cosmetic filling lines.

Water Treatment and Waste Management

Application: Dosing of coagulants, disinfectants, or nutrients in water or wastewater processes.
Gearbox Role:
- Regulates pump speed to adapt to varying flow conditions.
- Enables 24/7 continuous operation with consistent accuracy.
Examples: Chlorination systems, sludge conditioning.
