Tide AD3DC DC Micro Diaphragm Pump 1.2L/min 90kPa EPDM Low Power 1.6W for Compact Gas Sampling and Automation Systems

Introduction

As industrial and medical devices continue to move toward miniaturization and portability, system designers face increasing challenges in balancing performance, size, and energy efficiency.

Gas handling systems, in particular, require stable airflow control within extremely limited space and power budgets.

The AD3DC Micro Diaphragm Pump is developed to address these requirements in compact gas sampling and pressure control applications.

Challenges in Compact Gas Handling Systems

In modern embedded and portable systems, engineers commonly face the following limitations:

• Limited installation space
• Strict power consumption constraints
• Requirement for continuous or intermittent gas sampling
• Sensitivity to airflow instability in measurement systems
• Need for long-term operational reliability in small devices

These constraints make traditional pumping solutions unsuitable for compact integration.

Micro diaphragm pump technology provides a practical solution by enabling controlled gas flow in miniature systems.
