KNF Liquid Diaphragm Pump

Pulsation-reducing liquid pump, a high-output diaphragm liquid pump that significantly reduces pulsation generated during pump suction and discharge. Exhibiting at JASIS 2025.

We have reviewed the design of the pump itself as a liquid pump for pulsation reduction measures. Previously, pulsation reduction was achieved using dampers, but now the pump itself significantly suppresses pulsation. It features a high discharge specification. - FP1.7 Series / FP1.25 Series We have integrated the pulsation reduction damper with the pump. Two types are available: brushed DC motors and brushless DC motors. The brushless DC motor also allows for digital customization. We will be exhibiting at JASIS 2025, one of Asia's largest cutting-edge science and analysis systems & solutions exhibitions, where manufacturers of analytical and scientific instruments gather. Please visit our booth. We look forward to seeing you there. ■ Exhibition Name: JASIS 2025 ■ Date: September 3 (Wed) - 5 (Fri), 2025 (3 days) ■ Venue: Makuhari Messe International Exhibition Hall and Conference Center ■ Participation Fee: Free (Pre-registration required) ■ Booth Number: 6B-703

• Other pumps

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.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
