KNF’s new FK 1100 diaphragm liquid pump is one of the most advanced solution on the market for gentle, low-pulsation liquid pumping at high flow rates. This is required as for example by industrial inkjet, food processing or cooling circuit applications. The robust, adjustable pump is offered in a variety of materials, and comes in food-safe and chemically resistant versions.
The pump has only one inlet and one outlet, despite having three diaphragms working inside. These are offset at 120° to each other while connected in parallel, which results in very low pulsation and minimal shear forces. Intensive testing has proven that the pump easily achieves pulsation values below 200 mbar at the inlet and outlet. This permits the new pump to convey liquid very gently and to protect fragile elements of the media.
