Intelligent Features Allow Precise Control in Vacuum Pumps for Degassing
Intelligent Vacuum Control helps vacuum pumps for degassing maintain stable, application-specific vacuum levels.
Degassing is an essential process for a wide range of applications, such as Inkjet printing, medical diagnostics, sample analysis, dialysis, high-performance liquid chromatography (HPLC), and semiconductor. Regardless of application, reliable degassing systems largely depend on accurate and consistent vacuum. These stringent and specific requirements make diaphragm pumps with KNF’s intelligent feature Vacuum Control an optimal choice for degassing.
Why Stable Vacuum Matters in Degassing Systems
Degassing is the process of removing bubbles or dissolved gases from liquids in a given application. This could include reagents in diagnostics, inks used in inkjet printing, or dialysate used in dialysis systems. Degassing systems involve transporting the appropriate fluid into a gas permeable chamber. This chamber is then placed under a precise level of vacuum, making the bubbled gases less soluble. This allows the gas to be separated from the liquid and removed from the chamber. While the applications and liquids requiring degassing are highly varied, the process is essential for system performance. For example, gas bubbles in ink can adversely impact print quality and damage print heads in an inkjet system. In diagnostic equipment, gas bubbles can result in inaccurate dosing and skew test results.
These processes typically depend on degassing pump technology to generate the required vacuum quickly and consistently. Due to humid gases and minimal airflow in degassing applications, these pumps must also be capable of handling condensate, which could stop valves from moving. Harsh or dangerous liquids or vapors are also common, making good chemical compatibility essential. Additionally, these pumps must provide consistent, quiet performance over a long lifetime. Compact design is also essential, as degassing applications require pumps that can fit into complex systems without compromising performance.
Intelligent Feature Vacuum Control Provides Control Required for Degassing Systems
KNF’s intelligent feature Vacuum Control combines sensors, software, and motor technology to help diaphragm pumps deliver the precise levels vacuum pumps for degassing applications require. Depending on the application, the pump will be required to quickly generate and maintain a consistent vacuum, ranging anywhere from 600 mbar (abs.) for inkjet systems to as low as 100-200 mbar (abs.) for HPLC degassing. With the intelligent feature Vacuum Control, customers can define a target vacuum, and the pump will automatically adjust its performance to meet these set points, even if conditions change during operation. These closed loop vacuum control systems are highly customizable and can be tailored to specific applications.
The NVC 830.3 is equipped with KNF’s intelligent feature Vacuum Control for precise control. It is ideal for applications where a very strong vacuum is required.
NVC 830 Series for Precise Vacuum Pumps for Degassing
KNF’s NVC 830.3 is equipped with KNF’s intelligent feature Vacuum Control, making it an optimal choice as a degassing pump. It monitors vacuum levels and automatically adjusts to maintain the defined set point through a closed-loop system. The NVC 830.3 can create a maximum vacuum of 55 mbar (abs.) along with a flow rate of 2.6 l/min. It is highly compact, can be installed in any position and offers the high condensate resistance and contamination free transfer required of degassing operations.
The NVC 830.3 HP has a gas ballast integrated directly into the pump head to reduce condensation.
NVC 830.3 HP Features an Integrated Gas Ballast
The NVC 830.3 HP version is an ideal choice for applications where condensation is a substantial challenge. This pump has a gas ballast integrated directly into the pump head, allowing for additional airflow directly into the inlet side of the pump. This gas ballast promotes constant flow in a deep vacuum. It is equipped with a state-of-the-art motor capable of running both fast to quickly evacuate a chamber and remove condensate and slowly to maintain a stable vacuum. The NVC 830.3 HP generates a maximum vacuum of 80 mbar (abs.) with a maximum flow rate of 4.0 l/min. It maintains the chemical compatibility, low noise, and compact design required of degassing pumps.
The NVC 830 HP is equipped with KNF’s intelligent feature Vacuum Control, allowing it to automatically adjust in order to maintain customer specified set points.
For applications requiring less vacuum, the NVC 830 HP is also available. These pumps generate a maximum vacuum down to 200 mbar (abs.) while offering a maximum flow rate of 4.7 l/min. The NVC 830 HP is also highly resistant to condensates and offers strong chemical resistance.
