High conveying capacity with low pulsation

With a flow rate of around 12 liters per minute, the FK 1100 performs twice the previous maximum flow rate of KNF diaphragm liquid pumps. Although the pump has only one inlet and one outlet, three diaphragms work together inside. These are each offset 120° from each other and connected in parallel, resulting in very low pulsation and minimal shear forces. Extensive testing has shown that the pump easily achieves pulsation values of less than 200 mbar on both the inlet and outlet sides at rated power. The pump is further self-priming with 4.5 m H2O suction head and dry-run safe.

The modular system also applies to the FK 1100: brushless DC motors and single-phase AC motors are available for selection. The speed of the brushless DC motors can be controlled via analog or digital pulse width modulation(PWM) signals, allowing low flow rates if required.
