Water ring vacuum pump (abbreviated as water ring pump) is a crude vacuum pump. The ultimate vacuum it can obtain is 2000~4000Pa, and the serial atmospheric ejector can reach 270~670Pa. Water ring pumps can also be used as compressors, known as water ring compressors, which are low pressure compressors with a pressure range of 1 to 2 x 105 Pa gauge pressure.

The structure is simple, the manufacturing precision is not high, and it is easy to process.

Compact structure, high rotation speed of the pump, generally can be directly connected with the motor, no need to reduce the device. Therefore, with a small structure size, a large displacement can be obtained, and the footprint is also small.

The compressed gas is essentially isothermal, ie the process temperature of the compressed gas changes very little.

Because there is no metal friction surface in the pump chamber, it is not necessary to lubricate the pump and the wear is small. The seal between the rotating part and the fixing part can be done directly by the water seal.

Inhale evenly, stable and reliable work, simple operation, easy maintenance.

The Arm Piece is used to be connect with Suction Pipe, Turning Gland, etc. 

Here comes the photo of our Arm Piece:

Our cardanic joints/arm piece are available in a range from DN 600 up to DN 1400. Any other diameter is available on request. The units are made of a strong steel construction, which can be easily integrated into the side-suction pipe of all hopper dredgers. Cardanic joints/arm piece consist of two male arm pieces, a cardanic ring and a rubber fender hose.

The cardanic joint/arm piece allows movements of 30° in horizontal and vertical direction. It consists of two male arm pieces, a cardanic ring, a Rubber Hose and a rubber fender. The pivots are designed as steel shafts with high-wear-resistant bushes and have sufficient strength to bear the full load of the side suction pipe.
