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.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

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 to the base material. Repairs can be carried out even 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.
