VNY6216 High-Flow Speed-Controlled Miniature Vacuum Pump

Product Introduction
The VNY6216 High-Flow Speed-Controlled Miniature Vacuum Pump is a compact, oil-free vacuum pump designed for applications requiring adjustable airflow, reliable operation, and integration into automated systems. Powered by a 24 VDC brushless motor, it delivers a peak flow rate of up to 16 L/min and a maximum relative vacuum of approximately -62 kPa. These two maximum values cannot be achieved simultaneously.
Depending on the version selected, the VNY6216 supports speed regulation through frequency control or analog voltage control, allowing motor speed and pump flow to be adjusted using a signal line. Its low power consumption, lightweight construction, low-noise operation, and ability to handle moisture-laden gas make it suitable for embedded systems and continuous-duty applications.

Performance Features
• High peak flow: Delivers up to 16 L/min, with an average flow rate of approximately 9 L/min.
• Adjustable speed: Imported full-featured versions support frequency or analog voltage speed control; these options are alternatives rather than simultaneous functions.
• Brushless motor: Designed for long service life, frequent start-stop cycles, and continuous operation.
•   Compact and lightweight: Weighs approximately 580 g, making it suitable for space-constrained equipment.
• Oil-free operation: No oil lubrication is required, helping avoid oil contamination.
• Low electrical interference: Designed to minimize interference with nearby electronic components and control circuits.
•   Moisture tolerance: Suitable for gas containing water vapor.
•   Flexible installation: Can be installed in different orientations.
• Multiple connector options: Supports standard plastic connectors for silicone tubing or optional SMC-brand metal quick-connect fittings for compatible nylon tubing.
• Version-dependent protection: Reverse-polarity protection is specified across versions; overheat and overload protection are available on selected versions.
• Maintenance-friendly design: Durable moving components and brushless drive technology support reduced routine maintenance.

Working Principle
The VNY6216 uses a brushless DC motor to drive its internal pumping mechanism, drawing gas through the inlet and discharging it through the outlet. The resulting pressure difference creates vacuum at the inlet.
For versions equipped with speed control, a frequency or analog voltage signal adjusts motor speed, which in turn changes the pump's flow rate. The pump can operate with a heavily loaded or blocked inlet under the manufacturer's stated operating conditions, but the exhaust outlet must remain unobstructed to ensure proper operation.

Frequently Asked Questions (FAQ)
1. What is the VNY6216 miniature vacuum pump used for?
It generates vacuum for compact industrial equipment, laboratory instruments, automated systems, and other applications requiring controlled gas flow.
2. What is the maximum flow rate of the VNY6216?
The specified peak flow rate is 16 L/min, and the average flow rate is approximately 9 L/min.
3. What is its maximum vacuum pressure?
The specified relative vacuum pressure is approximately -62 kPa. The maximum flow rate and maximum vacuum cannot be achieved simultaneously.
4. Does the VNY6216 support speed control?
The imported full-featured version supports either frequency-based or analog-voltage-based speed control. Availability depends on the selected version.
5. What power supply does it require?
The pump operates at 24 VDC, with a specified load current below 1.2 A and power consumption below 28.8 W.
6. Does the pump require oil lubrication?
No. The VNY6216 is designed for oil-free operation, helping prevent oil contamination in the pumped gas.
7. What protection functions are available?
The domestic version is specified with reverse-polarity protection. The imported simplified version adds overload protection, while the imported full-featured version includes reverse-polarity, overheat, and overload protection, along with speed-control functionality.
8. Can the pump handle moisture-containing gas?
It is designed to tolerate gas containing water vapor. Confirm the permissible moisture level and condensate-handling limits for the intended application.
9. Can the inlet or outlet be blocked during operation?
The source states that the inlet can tolerate a high load, even blockage, under the intended operating conditions. The exhaust outlet must remain unobstructed. Follow the manufacturer's operating instructions to avoid damage.
