KNF FP Series Pulsation Control Diaphragm Liquid Pump
Pulsation-reducing liquid pump, a diaphragm liquid pump that significantly reduces pulsation generated during pump suction and discharge.
We have reviewed the design of the pump itself as a liquid pump for pulsation reduction measures. Traditionally, pulsation reduction was achieved using dampers, but we have significantly suppressed pulsation with the pump itself. - FP70 Series We have integrated the pulsation reduction damper with the pump. - FP150 / FP400 / FK1100 Series We have increased the number of diaphragms to a maximum of five, allowing for the cancellation of pulsation within the pump. - FP1.150 / FP1.400 / FK1.1100 Series We have increased the number of diaphragms to a maximum of five, allowing for the cancellation of pulsation within the pump. Additionally, we have improved the maximum allowable discharge pressure to 6 bar (0.6 MPa), achieving smooth liquid transfer even under challenging pressure conditions.

Whether it's turbulence or calm. It's up to you to decide.
From high-resolution inkjet printers to life-saving devices, KNF's advanced flow technology delivers smooth, turbulence-free performance in situations where precision is everything. Gentle Flow Pump – A groundbreaking product in diaphragm pump innovation KNF's Gentle Flow series employs two advanced design techniques to achieve minimal pulsation. One is a design that uses an internal damper integrated within the pump to absorb pressure fluctuations. The other is a design that connects up to five diaphragms in parallel, operating each with a phase difference to smooth the flow. Both configurations minimize vibration and noise, enabling precise flow control through a built-in brushless DC motor.
