Twice the Flow, Minimal Pulsation

NFB 100 Diaphragm Pump for Liquid Handling Applications

NFB 100 Liquid Handling Pump

The KNF boxer-style NFB 100 diaphragm pump is powerful and compact. Featuring 2 pump heads driven by a single motor, the NFB 100 liquid handling pump produces a smooth, adjustable flow.

The NFB 100 is a standout from KNF's NFB liquid diaphragm pump series. The two-headed, "boxer-style" design of the NFB 100 liquid handling pump allows for high flow rates (up to 2.6 L/min), while maintaining half the pulsation of a single-headed pump. Furthermore, it can be used to transfer two different liquids simultaneously, thereby eliminating the need for a second pump. Driven by an adjustable brushless DC motor, the flow rate of the NFB pumps can be regulated and matched to the specific performance parameters in your system. As always, KNF encourages OEM design engineers to customize our pumps to their unique performance needs using spec-driven configurations, materials, and motors.

Operating Modes

1. Parallel Connected Mode:

The alternating "boxer-style" operation of the NFB pump heads result in a smooth and level flow.

2. Individual Mode:

Two different liquids can be transported at the same time, making a second liquid transfer pump superfluous.
