Nikuni Co., Ltd. List of Products and Services

The Nikuni liquid-sealed (water-sealed) vacuum pump is a liquid-sealed (water-sealed) vacuum pump that excels in safety and economy. ■ Safety The pump performs gas suction and compression by the movement of water in each cell of the impeller, so there is no issue with transporting gases that contain water or water vapor. There is no metal contact inside the pump, and it is completely sealed by a liquid film, resulting in no leakage. This makes it suitable for the suction and compression of explosive or highly corrosive gases. ■ Economy We have pursued economy through a high-efficiency design, significantly reducing power consumption. (Energy savings of 30% compared to two-stage pumps are possible.) The water-sealed structure ensures that gas leakage is virtually nonexistent, making it effective for the transport and compression of expensive gases. ■ Other... It achieves low noise levels. Since suction and compression occur continuously for each cell of the impeller with one shaft rotation, there is no pulsation or vibration. Additionally, when combined with a silencer separator, the noise is kept extremely low. *For more details on the liquid-sealed (water-sealed) vacuum pump, please download the catalog or contact us.

Nikuni's liquid-sealed (water-sealed) vacuum pump excels in safety and economy. ■ Safety The pump performs gas suction and compression through the piston motion of water in each cell of the impeller, allowing for the transfer of gas containing mist or water vapor without any issues. There is no metal contact inside the pump, and it is completely sealed by a liquid film, preventing leaks and making it suitable for the suction and compression of explosive or highly corrosive gases. ■ Economy With a high-efficiency design, it pursues economic benefits and significantly reduces power consumption (up to 30% energy savings compared to two-stage models). The liquid-sealed structure ensures there are no gas leaks, making it effective for the pumping and compression of expensive gases. ■ Low Noise Since suction and compression occur continuously for the number of cells in the impeller with each shaft rotation, there is no pulsation or vibration. Additionally, when combined with a silencer separator, the noise is kept extremely low. ■ Durability The simple and robust structure, along with the absence of sliding parts or mechanical contact except for the sealing area within the pump, contributes to its excellent durability. Its side air inlet structure is resistant to wear, maintaining high performance for a longer period compared to internal air inlet types. ■ Cleanliness There is no generation of oil mist like in oil rotary types, ensuring a clean environment is maintained.

It has high self-priming capability and can draw in air from the suction side even if it gets mixed in. It leaves almost no liquid at the bottom of the tank.

The Nikuni liquid-sealed (water-sealed) vacuum pump excels in safety and economy. The coupling direct type and belt-driven liquid-sealed vacuum pump "LV102/LV202" performs gas suction and compression by the piston motion of water in each cell of the impeller, allowing for the transfer of gases containing water or water vapor without any issues. There is no metal contact inside the pump, and it is completely sealed by a liquid film, preventing leaks and making it suitable for the suction and compression of explosive or highly corrosive gases. The high-efficiency design pursues economy and significantly reduces power consumption. 【Features】 - Excellent safety - Excellent economy - Achieves low noise *For more details on the liquid-sealed (water-sealed) vacuum pump, please download the catalog or contact us.

The one-stage liquid-sealed vacuum pump "HVSD" is a new product that not only offers excellent vacuum performance but also reduces the amount of make-up water. It suppresses cavitation even at high vacuum levels, prevents noise generation, and contributes to the longevity of components. 【Features】 ■ Achieves high vacuum operation at 4 kPa without an air ejector ■ Reduces make-up water consumption by 30% compared to our conventional models ■ Contributes to factory SDGs initiatives ■ Improves operational stability *For more details, please refer to the catalog available for download in PDF format.
