Key Technical Specifications

Applications & Industries

The HC680A2-24L is engineered to serve as the foundational vacuum source for a wide variety of precision industries. In the laboratory sector, it is heavily utilized for applications that demand absolute purity. Equipment such as vacuum filtration manifolds, rotary evaporators, and vacuum drying ovens benefit immensely from the pump's oil-free design. Because the unit operates at a quiet ≤60dB(A), it can be placed directly on or under a lab bench without creating a disruptive work environment for researchers and technicians.

In the realm of manufacturing and logistics, this pump is highly effective for packaging and pick-and-place automation. Pick-and-place robotics require immediate, consistent suction to lift, move, and deposit components ranging from delicate microchips to heavy non-porous materials. The inclusion of the 24-liter tank is critical here; it acts as a vacuum buffer, allowing the system to handle sudden, high-volume suction demands without waiting for the pump to build pressure. Furthermore, in packaging machinery, specifically modified atmosphere packaging (MAP) and vacuum sealing, the 120 L/min flow rate ensures rapid evacuation of air from packaging materials, increasing the overall throughput of the production line.

Medical suction applications also rely heavily on the precise specifications of the HC680A2-24L. Medical device manufacturers integrate these pumps into surgical aspirators and airway clearance devices where hygiene and reliability are non-negotiable. The dry-running nature of the pump ensures that no exhaust oil is expelled into the sterile clinical environment. With its Class F motor insulation and 145±5℃ thermal protection, the pump is built to operate safely during lengthy medical procedures without the risk of thermal failure, providing peace of mind to both equipment manufacturers and healthcare providers.

Certifications & Compliance

For B2B procurement professionals and OEM engineers, regulatory compliance is just as critical as mechanical performance. The HC680A2-24L carries the CE mark, indicating full conformity with European health, safety, and environmental protection standards. This certification is mandatory for any equipment sold within the European Economic Area (EEA), ensuring that the pump meets strict directives regarding low voltage safety and electromagnetic compatibility. By sourcing a CE-certified component, OEMs can expedite the certification process of their final assembled machines for the European market.

Additionally, the pump is fully RoHS compliant. The Restriction of Hazardous Substances directive ensures that the manufacturing of this unit does not involve dangerous levels of lead, cadmium, mercury, or other restricted materials. This is particularly vital for integration into medical devices and laboratory equipment, where environmental and human safety regulations are most stringent. Finally, HCEM Pump operates under an ISO 9001 certified quality management system. This guarantees that every HC680A2-24L unit is produced with strict quality control, full material traceability, and consistent manufacturing protocols, reducing the risk of defects and ensuring long-term reliability for bulk purchasers.

Frequently Asked Questions

What thermal and electrical safety features are included for continuous duty operation?

The HC680A2-24L is highly equipped for safe, continuous operation. It features a built-in thermal protection switch that automatically interrupts power if the internal temperature reaches 145±5℃, preventing catastrophic motor failure. Additionally, the motor utilizes Class F insulation, which is rated to safely handle internal temperatures up to 155℃. This provides a secure safety margin between the thermal shut-off point and the maximum insulation threshold, ensuring long-term durability.

Is the HC680A2-24L suitable for medical suction and clinical environments?

Yes, this model is highly suitable for medical suction devices. Because it is an oilless vacuum pump, it does not emit any oil mist or hydrocarbon vapors into the ambient air, maintaining the strict hygiene standards required in clinical settings. Furthermore, its low noise output of ≤60dB(A) ensures it will not disturb patients or medical staff. The vacuum pressure of -92Kpa to -98Kpa is more than sufficient for standard surgical aspiration and fluid removal tasks.

Can this pump be configured to match different regional power standards for global distribution?

Absolutely. The HC680A2-24L series is manufactured in two distinct electrical configurations to support global OEM distribution. The HC680A-24L model is wired for 220V/50Hz/1 phase power, utilizing a 20μF capacitor and operating at 1400 rpm, making it ideal for European and Asian markets. The HC680B-24L model is designed for 110V/60Hz/1 phase power, utilizing a 60μF capacitor and operating at 1700 rpm, specifically tailored for the North American market. Both configurations deliver the exact same ≤340W power efficiency and physical dimensions.
