KNF Expands Smooth Flow Series with FP 7 and FP 25 Liquid Pumps
The latest members of the KNF Smooth Flow family are designed to meet the most demanding applications.
KNF has expanded its Smooth Flow series with the introduction of the new FP 7 and FP 25 low pulsation pumps. Combining the gentle flow characteristics of gear and centrifugal pumps with the advantages of diaphragm pumps, these innovative additions to the Smooth Flow family are designed to meet the needs of the most demanding applications.
KNF FP 7 and FP 25 Advance Liquid Pump Technology
With the FP 7 and FP 25, KNF has added two new customizable pumps to its FP series. Designed with a built-in dampener to provide smooth, low-pulsation flow that minimizes friction in tubing and prevents bubble formation, these pumps reliably transfer fluids without the need for additional equipment like external dampeners. Other features include 4-point valves for reliable self-priming, even at reduced motor speeds, and a digitally adjustable BLDC motor for precise pump control and pinpoint matching to individual electronics.
The KNF FP 7 and FP 25 Smooth Flow pumps feature a built-in dampener for exceptionally low pulsation.
For a Variety of Applications: FP 7 and FP 25
The FP 7 has a nominal flow rate of 70 ml/min, a minimum suction height of 2.0 mH2O, and a maximum pressure of 10 mH2O. The FP 25 shares many of the same features as the FP 7, including the integrated dampener, innovative 4-point valves, and digitally customizable BLDC motor. However, it offers a higher nominal flow of 250 ml/min and a higher minimum suction height of 3 mH2O. Also available in high-pressure versions, both FP 1.7 and FP 1.25 achieve nominal pressures up to 60 mH2O.
Maximizing Efficiency Through Customization
Like most KNF pumps, the new FP 7 and FP 25 are fully customizable to meet the specific needs of various applications. Pump head, valve and diaphragm materials can be matched to specific operating requirements, and a variety of DC motors are available, from simple brushed versions to advanced BLDC versions for digital customization and superior controllability, making these pumps an excellent choice for demanding applications such as inkjet printing, medical equipment, 3D printing and fuel cells. The ability to handle solvents and other demanding liquids further expands the range of applications.
