FluidSmart Tidesmart AD5A(H)DB12/24V Micro Diaphragm Pump for Gas Sampling and Analytical Instruments

Gas analysis systems depend on a reliable sampling process. Before a gas sample reaches the analyzer, it needs to be transported through tubing, filters and other components under controlled conditions.

This makes the sampling pump an important part of the overall instrument.

For equipment manufacturers developing compact gas analyzers, environmental monitoring instruments and laboratory systems, the ideal pump is not necessarily the largest or most powerful option. Instead, the pump needs to match the sampling process while providing reliable gas transfer, suitable material compatibility and easy system integration.

The Role of a Pump in Gas Sampling

A gas sampling system typically draws gas from a specific location and delivers it to an analytical module.

The pump provides the driving force for this process.

If the gas flow is unstable, the analyzer may not receive a consistent sample. If the pump has excessive leakage, the composition of the sample can potentially be affected. Material compatibility is also important when the sampled gas contains corrosive or aggressive components.

Therefore, pump selection should be considered as part of the entire sampling system rather than as an isolated component.

Gas Sampling for Analytical Instruments

The FluidSmart Tidesmart AD5A(H)DB12/24V Micro Diaphragm Pump is designed for compact gas sampling applications where reliable sample transfer is required.

Its single-head diaphragm configuration allows the pump to be integrated into relatively small instrument housings.

This makes it suitable for applications such as:

• Gas analyzers
• Gas sampling instruments
• Environmental monitoring equipment
• CEMS systems
• Laboratory analytical instruments
• Medical analytical equipment
• Industrial gas monitoring systems

In these applications, the pump can be used to draw and transport sample gas between the sampling point and the analytical module.

Supporting Clean Sample Gas Transfer

For analytical instruments, maintaining the quality of the sample gas is essential.

The pump uses an oil-free diaphragm pumping principle, helping avoid oil contamination during gas transfer. The diaphragm and valve use FKM material, providing resistance to a variety of gas environments.

A professional sealing structure further supports low-leakage operation.

These characteristics make the pump suitable for sampling systems where the gas path needs to remain clean and isolated from potential contamination sources.

Compact Integration for Instrument Manufacturers

Instrument designers often face a familiar engineering problem: there is never quite enough space inside the enclosure.

A sampling pump therefore needs to provide the required pumping function without unnecessarily increasing the size of the overall system.

The compact structure of the AD5A(H)DB12/24V makes it suitable for integration into gas analyzers, monitoring instruments and laboratory equipment where internal space is limited.

Its 12V/24V DC configuration also makes it convenient for integration into equipment using low-voltage DC power systems.

Long-Term Operation in Monitoring Equipment

Environmental monitoring and analytical instruments may need to operate continuously for extended periods.

For this reason, pump reliability can directly influence equipment maintenance requirements and overall system availability.

The AD5A(H)DB12/24V uses a DC brushless motor with a rated lifetime of more than 8,000 hours, providing a long-life pumping solution for equipment designed for extended operation.

Flexible Flow Control for Sampling Systems

Different analytical systems can require different sampling conditions.

The AD5A(H)DB12/24V supports PWM speed control, allowing equipment manufacturers to adjust pump operation according to system requirements.

FG feedback can also provide motor operating information to the control system, making the pump easier to integrate into equipment that requires monitoring and automated control.

This is particularly useful for analytical instruments where gas flow needs to be coordinated with the measurement process.

Applications Beyond Gas Analysis

Although gas sampling is a key application, the pump can also be considered for other systems requiring compact, clean and controlled gas transfer.

Potential applications include:

Environmental Monitoring
Used in equipment for continuous monitoring and analysis of environmental gases.

Laboratory Instruments
Suitable for compact analytical systems where controlled gas sampling is required.

Medical and Analytical Equipment
Can be integrated into equipment requiring small-scale gas movement and sampling.

Industrial Gas Monitoring
Useful for systems that need to continuously draw and transport gas samples to an analysis module.

OEM Equipment
The compact structure and control options allow the pump to be integrated into customized equipment designs.

A Pump Designed Around the Application

The role of a micro diaphragm pump in a gas analysis system is easy to overlook.

But stable sampling, clean gas transfer, reliable sealing and long-term operation all contribute to the performance of the final instrument.

The FluidSmart Tidesmart AD5A(H)DB12/24V is designed around these requirements, providing a compact pumping solution for gas sampling, gas analysis, environmental monitoring and analytical equipment.

For instrument manufacturers, the goal is not simply to find a pump that can move gas. It is to find a pump that can become a reliable part of the entire sampling system.
