Low-Pulsation Diaphragm Liquid Pump
KNF “Smooth Flow” series provides extraordinarily low pulsation comparable to gear and centrifugal pumps while offering benefits from diaphragm pumps.
The FP 1.400 is a self-priming, dry-run safe liquid pump delivering a flow rate of up to 4.4 l/min with outstanding chemical resistance and the ability to handle sensitive media gently.
The FP 1.400 supports adjustable flow rates along with excellent linearity. Its BLDC motor can be controlled via PWM-inverse or Vctrl.
Other notable features include continuous operation even at high pressure, long service life, low sound level, and IP 65 protection.
An NSF-certified model is available for food and beverage equipment.
