With the introduction of FP 70, KNF further expands its series of smooth flow liquid pumps. This product line combines the low pulsation of a gear or centrifugal pump with the strengths and advantages of diaphragm pumps.
KNF FP 70可提供高达850毫升/分钟，同时在连续操作下产生高达29.4 PSIG（2巴）压力。由于获得专利的4点阀，即使在非常低的电动机速度下，KNF FP 70也可靠地自吸引。它还可以安全地运行干燥，轻轻处理液体转移，并具有化学抗性流动路径材料。由于脉动阻尼技术的整合，当使用KNF FP 70时，不需要额外的脉动阻尼元件和管道，从而降低空间要求与泵加阻尼方法。
The versatile FP 70 is available with a selection of motors to match the functionality and lifetime requirements of the application – from high-end BLDC to lower-end DC motors. Depending on the operating parameters, the high-end BLDC motor achieves a lifetime of more than 20,000 hours. Furthermore, the parameters of these motors can be customized at KNF to dial in the desired control behavior, performance characteristics, and pump accuracy. Additional options include a selection of hydraulic connections and a variety of flow path materials, including an NSF food grade version. Combined with all these options is KNF’s ability to further optimize pumps to customer needs at any lot size.
FP 70非常适用于各种应用，包括医疗技术，喷墨，3D印刷和分析仪器。它加入了一个越来越多的KNF平滑流动液位膜泵，现在拥有从120毫升/分钟的流速范围到12.4L / min。
The Benefits of Low-Pulse, Smooth Flow Pumps
集成的低脉动技术以各种方式提供价值：
- Increased Pump Efficiency: the pressure resistance in a system’s tubing is reduced which significantly improves flow performance and accuracy. This can be a critical factor when small ID tubing is used. Smooth flow also increases the flow/power consumption ratio.
- 长寿命：下压峰意味着对所有流体系统组件的压力较小，导致组件寿命更长，维护间隔更长。
- 节省空间：将阻尼系统集成到泵中，消除了包括单独阻尼器的需要，从而消除额外的管道和配件（以及两个潜在的泄漏点！）
- Less Bubble Formation: The potential for bubble formation is reduced, thereby increasing the reliability of the system.
- 流量传感器成本节省：具有低压峰值的流量允许使用常见的低成本流动传感器 - 例如叶轮传感器 - 同时保持足够的精度来调节流速。这提供了成本节约的潜力，因为可以根据大压变化应付的流动传感器可以很贵。
