This is a compact liquid-sealed (water-sealed) vacuum pump with low noise and excellent durability, featuring an integrated motor.
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.

Company information
Nikuni Co., Ltd. is a company (manufacturer) engaged in the development, production, and sales of pumps. In particular, we focus on the development, production, and sales of products centered around vortex turbine pumps, as well as the development, production, and sales of devices that improve the environment within factories by incorporating pumps (such as coolant systems and filtration systems). Pumps are the heart of devices and equipment. As a precision machinery manufacturer, Nikuni has been producing high-precision, high-quality components for many years. Utilizing our machining technology, Nikuni produces pumps with precision that exceeds the norms of general pumps (such as perpendicularity, parallelism, concentricity, and runout), resulting in pumps that pursue high precision and high quality. To prevent issues, we conduct a full inspection of all pumps before shipment, ensuring that only those that meet Nikuni's quality standards are shipped. Nikuni manufactures and sells products so that everyone involved with pumps can use them with confidence.
