Pulsation Reduction Gentle Flow Diaphragm Liquid Pump

- The pulsation reduction feature allows for the transfer of liquids with minimal pulsation. - Due to the reduced pulsation, pressure loss in the tubing can be minimized. - It enables the transfer of liquids with fewer air bubbles. - It can reduce the optional parts for pulsation reduction measures. - Equipped with a newly developed valve, it can achieve self-priming suction even at lower motor speeds. - Flow rate adjustment is possible through brushless motor control. - Materials with NFS certification are also available. Basic flow rate: 700 ml/min Diaphragm material: EPDM / PTFE

The "Nautilus Fluidics" simulation application is now available for your use.

  • NEW
  • Company news

KNF's web-based software application "Nautilus" helps customers digitally simulate fluid systems and identify optimal gentle flow pump solutions. Nautilus is now available for testing by customers at KNF.com. By using this web-based fluid simulation application, users can recreate their systems digitally and compare the performance of various gentle flow pumps before integration. Fluid simulation software supports more efficient pump selection. With a simple drag-and-drop interface, customers can build simulations of their systems using components such as pumps, reservoirs, valves, and filters. By adding values relevant to their application, they can replicate actual operating conditions and assist in more accurate pump selection. "Nautilus" is compatible with KNF's gentle flow pumps. Nautilus can shorten the pump selection process through early and easy digital testing, reducing the need for physical testing and on-site support.

Liquid suction: direct liquid transfer and liquid overhead vacuum transfer

  • Product news

Liquids can be suctioned using either direct liquid transfer or vacuum over liquid methods. It is important to understand these differences when selecting the appropriate technique and pump solution. While liquid suction may seem like a simple task, choosing the right suction method can be challenging. One option is direct liquid transfer, where the medium is transferred directly using a liquid pump. In vacuum over liquid transfer, a vacuum is used to suction the liquid. Both methods have their advantages, but there are also limitations. Understanding these differences is crucial to meet the specific requirements of the application. If the focus is on liquid transfer rather than liquid suction, the lesser-known method of pressurized liquid transfer may serve as an alternative.

Whether it's turbulence or calm. It's up to you to decide.

  • Product news

From high-resolution inkjet printers to life-saving devices, KNF's advanced flow technology delivers smooth, turbulence-free performance in situations where precision is everything. Gentle Flow Pump – A groundbreaking product in diaphragm pump innovation KNF's Gentle Flow series employs two advanced design techniques to achieve minimal pulsation. One is a design that uses an internal damper integrated within the pump to absorb pressure fluctuations. The other is a design that connects up to five diaphragms in parallel, operating each with a phase difference to smooth the flow. Both configurations minimize vibration and noise, enabling precise flow control through a built-in brushless DC motor.
