Single Stage Water Ring Vacuum Pump, Gujarat, India.

Pidee Pumps is a well known manufacturer and exporter of a single-stage water ring vacuum pump, it is a type of vacuum pump that uses water as the working fluid to create a vacuum. It operates on the principle of a rotating impeller, which creates a ring of water inside the pump casing. As the impeller rotates, it forces air or gas to be trapped in the water ring and then expelled out of the pump.

Here's how it typically works:

1. Impeller: The impeller is typically mounted off-center within the pump casing and connected to a shaft. When the impeller rotates, it creates a rotating water ring inside the casing.
2. Water Seal: Water is continuously introduced into the pump casing to form the water ring. This water also acts as a seal between the impeller and the casing.
3. Compression: As the impeller rotates, it creates a space between the vanes. Gas or air is drawn into this space, and as the impeller continues to rotate, the space becomes smaller, compressing the gas.
4. Expulsion: As the gas or air is compressed, it is pushed towards the outlet of the pump. The rotation of the impeller maintains the continuous movement of gas from the inlet to the outlet.
5. Water Separation: After passing through the pump, the gas is typically discharged into a separation chamber where any remaining water droplets are separated from the gas. The water can then be recirculated back into the pump.

Single-stage water ring vacuum pumps are commonly used in applications where a moderate vacuum level is required, such as in industries like chemical processing, food packaging, and pharmaceutical manufacturing. They are known for their simplicity, reliability, and ability to handle wet or saturated gases. However, their efficiency tends to decrease at higher vacuum levels, and they may not be suitable for applications requiring very high vacuum levels.
