From Insulin Pumps to Fluid Delivery Devices
In medical technology, reliability is a requirement. Devices such as insulin pumps, infusion systems and other fluid delivery solutions depend on precise, continuous motion to ensure correct dosing and patient safety.
Even minor deviations in performance can affect therapy outcomes. That is why drive systems used in medical applications must combine precision, efficiency and long-term stability.
Motion Requirements in Fluid Delivery Devices
Applications such as insulin pumps require drive systems that offer:
- High positioning accuracy for micro-dosing
- Low power consumption for battery-driven devices
- Compact design for wearable and portable systems
- Quiet and smooth operation
- Long service life with minimal performance drift
In these systems, compact motors are typically combined with gearheads and encoders to achieve controlled, repeatable fluid delivery. Such solutions are widely used in external infusion systems as well as implantable devices where durability and reliability are critical.
Case Example: Insulin Pumps – When Reliability Becomes Life-Critical
In the article“Reliability Is Everything,” maxon highlights insulin pumps as a clear example of why drive system reliability is crucial in medical technology.
In this specific case, a compact EC 9.2 flat motor is used within the pump to ensure precise and continuous insulin delivery. The motor converts controlled rotational motion into accurate fluid displacement, enabling extremely small and repeatable dosage steps.
Because insulin pumps operate continuously and are often worn by patients for extended periods, the drive system must provide stable performance over long service life. High efficiency, minimal wear, controlled thermal behavior, and predictable long-term operation are therefore essential characteristics.
The example illustrates how reliability in medical technology depends not only on motor performance, but also on validation, lifetime testing and controlled manufacturing processes. In life-sustaining devices such as insulin pumps, failure is not merely technical, it directly affects patient safety.

Reliability by Design
As emphasized by maxon, reliability in motion systems is achieved through careful design, material selection and rigorous validation. In medical technology, components must withstand continuous operation while maintaining consistent performance over time.
For medical applications, maxon develops and manufactures drive systems within ISO 13485-certified quality management processes, supporting the strict regulatory requirements of the healthcare industry.
