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.
