KNF Flodos introduces two OEM diaphragm pumps, FF 12 and FF 20, to transfer and suck up liquids and liquid/gas mixtures. The two models form the basis of a modular platform that allows countless customer-specific modifications. Depending on the respective model, the pumps transfer up to 230 ml/min and can operate with up to 3 bar pressure.
Equipped with high-quality brushless DC motors, the pumps require no maintenance and have a service life of up to 20,000h. Models with brush-commutated DC motors are available for customer applications that do not require such a long service life. Use of resistant materials enables aggressive media to be transferred and the welded head parts ensure absolute leakproofness even with very volatile media.
With the tried and tested diaphragm technology from KNF Flodos, the medium is transferred extremely gently, which allows optimum handling of sensitive liquids. There is no contamination from wear and tear, as is the case, for example, with gear pumps. The pumps are also dry-run proof and self-priming. All of this guarantees the highest level of reliability in the customer’s application.
The two basic types cover a wide range of operations. At atmospheric pressure, the FF 12 transfers approximately 140 ml/min and can be operated continuously up to a pressure of 1 bar. The FF 20, which has a similar design but is more powerful, transfers around 220 ml/min and can be used continuously at pressures up to 3 bar. The easily adjustable brushless DC motors allow the transfer rate to be varied at a ratio of approximately 10:1. The suction head of the pumps is not affected by this and, depending on the model, is 2 to 3.5 meters in a dry condition.
A mounting plate with click-on mechanism facilitates installation in and removal from the customer's system, as it reduces the effort required for time-consuming tightening of screws. A wide range of hydraulic connections and different motor types in the most common voltages allows alignment to the customer’s needs, which further simplifies integration into the system.
