Vacuum Pump System

Vacuum Pump System

In modern industrial processes such as chemical production, pharmaceutical drying, coating, and vacuum distillation, vacuum pumps play a vital role in maintaining low-pressure environments for safe and efficient operations. However, any interruption in gas flow — caused by pipeline blockage, leakage, or system failure — can lead to equipment damage, process interruption, or even safety hazards.

To ensure stable vacuum conditions and prevent operational risks, accurate flow monitoring has become essential, especially in hazardous areas where flammable gases or vapors may exist.

What Is a Vacuum Pump System?

A vacuum pump system is used to remove gas molecules from a sealed chamber to create a low-pressure or vacuum environment. It is widely applied in chemical production, pharmaceutical drying, coating, packaging, and vacuum distillation processes.

Such systems help improve product purity, enhance production efficiency, and ensure controlled processing under low-pressure conditions. Depending on the process medium, vacuum pumps may handle flammable, corrosive, or high-temperature gases, which brings higher safety requirements to the monitoring instruments used.

How Does the ZINACA Instrument Apply in Vacuum Pump Systems?

ZINACA Instruments’ Explosion-proof Thermal Flow Switch is specially designed to provide real-time monitoring of gas flow in vacuum pump pipelines. Based on the thermal dispersion principle, the device senses the heat loss caused by the flowing medium.

When the gas flow falls below the preset limit, the switch immediately outputs a control or alarm signal to protect the vacuum pump from dry running, overheating, or abnormal operation.

Its explosion-proof structure (Ex db IIC T6 Gb) and IP66 enclosure allow it to perform reliably even in harsh and hazardous industrial environments. The switch’s compact size, high sensitivity, and maintenance-free design make it an ideal choice for continuous process lines and automated vacuum systems.

Choosing a Reliable Explosion-proof Flow Switch

When selecting a thermal flow switch for vacuum systems, several factors must be considered:

Explosion-proof certification: Ensure the product complies with international explosion-proof standards.

Response time: Fast detection prevents equipment damage during flow interruptions.

Material and protection level: Stainless steel construction and IP66 protection guarantee long-term durability.

Signal output compatibility: Choose models supporting relay, PNP/NPN, or analog outputs to integrate with your control system.

ZINACA Instruments provides customized flow switch configurations to meet specific installation, medium, and environmental requirements.
