Leak-Tight FL 10 Liquid Transfer Pump Prevents Uncontrolled Flow

The latest addition to KNF's extensive line of diaphragm liquid pumps, the FL 10 transfers aggressive, and even volatile fluids, safely and efficiently.

Integrated Leak-Tight Valve Function

The compact and durable FL 10 diaphragm pump features integrated NC valve technology which prevents uncontrolled flow and back-flow of media when not in use. This unique function prevents liquid from flowing, uncontrolled, through the pump head without the need for additional check valves. 

Smooth Transfer of Volatile Liquids

An integrated resonating chamber enables the FL 10 diaphragm pump to gently transfer liquid media by absorbing pressure peak disruptions.

Linear and Quick Adjustment of Flow Rate

When actively transferring liquid media, the FL 10 transfer pump displaces fluid at a flow rate of 0 - 100 mL/min. Flow rate adjustments are fast and easy thanks to signal frequency modulation. These features greatly simplify integration into your system, thus saving time and money.

Built to Last

Featuring self-priming and dry-run safe operation, the FL 10 liquid transfer pump offers an exceptionally long-lifetime (10,000 hours or 1.8 billion strokes) of maintenance-free operation even when used with aggressive media. Moreover, the pump's IP65 protection can withstand rigorous operating conditions.

1. VARIOUS VOLTAGES

The FL 10 is available with coils for the following voltages: - 24V DC - 230V AC / 50HZ - 115 AC / 60 Hz. The integrated freewheeling diode prevents feedback of discharge spikes into your system and makes suppression measures unnecessary.

2. PRECISE ACTUATION

With the DC-P version, flow rate can be adjusted quickly and precisely between 0 and 100 ml/min by adjusting signal frequency. Or, select an AC version for 50 or 60 Hz operation, depending on the region.

3. COMPACT AND ROBUST DESIGN

The linear, space-saving design simplifies installation into compact units. Built for operation in demanding conditions such as wet or dry areas, the pump’s IP protection class reduces the need for additional protection measures in your system. Furthermore, sealing between pump housing and the linear drive ensures fail-safe operation, so that in rare cases of a ruptured diaphragm, liquid is kept away from other areas of the system.

4. INTEGRATED VALVE FUNCTION

Spring tension in the linear drive ensures flow tightness in both directions when the FL 10 is switched off. Thus, uncontrolled liquid flow and backflow is prevented without the need for additional valves.

5. RELIABLE KNF DIAPHRAGM TECHNOLOGY

Thanks to the well-proven KNF diaphragm technology, the medium is transported extremely gently, which is of benefit especially in the case of sensitive fluids. Furthermore, there is no contamination from wear particles, as in the case of gear pumps, for example. Combined with long-lasting linear drive technology and outstanding dry-run properties, this results in pumps that are maintenance-free throughout their entire service life.

6. DURABLE MATERIALS

Chemically-resistant flow path materials such as FFKM and PTFE are used in the FL 10, ensuring reliable transportation of a wide range of aggressive media.
