KNF introduces two OEM diaphragm pumps, FF 12 and FF 20, to aspirate, transfer, and pressurize liquids and liquid/gas mixtures. Depending on model, the pumps transfer up to 230 mL/min and generate up to 44 psig. Easily adjustable brushless DC motors allow the transfer rate to be varied linearly at a ratio of approximately 10:1. The suction head of these pumps is not affected by this, and, depending on the model, can self-prime up to 5.8 – 10.5 InHg. The two models form the basis of a modular platform that allows countless customer-specific modifications. A wide range of hydraulic connections, wetted materials, and different motor types in the most common voltages allows alignment to customer needs, further simplifying system integration.
