The integrated, space-saving damper provides smooth, low pulsation flow that minimizes flow resistance, reduces vibration and noise, reduces liquid shear forces, prevents bubble formation, and reduces stress for longer pump and system component life.

KNF further expands its Smooth Flow series, with the introduction of FP 7 and FP 25. These new liquid pumps deliver adjustable flow rates from 15–70 ml/min and 50–250 ml/min, respectively. Both pumps produce up to 1 bar (14.5 psi) pressure. High-pressure FP 1.7 and FP 25 versions achieve nominal pressures up to 6 bar (87 psi).

The integrated, space-saving damper provides smooth, low pulsation flow that minimizes flow resistance, reduces vibration and noise, reduces liquid shear forces, prevents bubble formation, and reduces stress for longer pump and system component life. Other features include four-point valves for reliable self-priming even at reduced motor speeds, and a digitally adjustable BLDC motor for precise pump control. Options include flow path materials, fitting connections, pump mounts, motors, and boxer configurations. 

Ideal applications include medical equipment, inkjet printing, 3D printing, fuel cells, and solvent handling.

These new pumps join a growing line of KNF Smooth Flow pumps, with a nominal flow rate range from 15 ml/min–12.4 l/min.
