The FK 1100 diaphragm liquid pump from KNF USA is said to be one of the most advanced solutions on the market for gentle, low-pulsation flow. The 12 L/min flow rate doubles the company’s previous maximum for liquid diaphragm pumps.
The KNF USA unit has only one inlet and one outlet, despite having three diaphragms.
These are offset by 120° from each other while connected in parallel, resulting in very low pulsation and minimal shear forces, the company says.
Intensive testing has proven that the pump easily achieves pulsation values below 200 mbar at the inlet and outlet, it adds.
The pump has a die-cast aluminum housing and high-torque motor options that provide continuous operation with up to 87 psig back pressure.
The pump is self-priming with a 13.5 inHg suction height and is also able to run dry.
