SZ Series Water Ring Vacuum Pump - Single Stage Water Ring Vacuum Pump
The SZ series water ring vacuum pumps are available in four sizes: SZ-1, SZ-2, SZ-3, and SZ-4. These pumps are widely used for creating vacuum and pressure in closed systems by pumping or compressing non-corrosive and water-insoluble gases. The maximum vacuum range they can generate is between 86% and 95%. For example, the SZ-1 and SZ-2 models can achieve a maximum pressure of 1.0 to 1.4 kg/cm², while the SZ-3 and SZ-4 models can reach up to 1.5 kg/cm² under standard motor power, and even higher when the motor power is increased.

These pumps are ideal for various industrial applications such as condensate removal, ash handling, and circulation systems. The design of the pump includes an eccentrically mounted impeller inside the casing, which creates a rotating water ring during operation. This water ring helps to form the necessary suction and compression chambers within the pump. As the impeller rotates, the volume of the chamber changes, allowing air to be drawn in and compressed before being discharged. To maintain efficiency and prevent overheating, cold water is continuously supplied to the system.

The working principle of the SZ water ring vacuum pump is based on the rotation of the impeller, which generates a centrifugal force that forms a water ring against the inner wall of the pump casing. During each rotation, the volume of the gas chamber expands and contracts, enabling continuous suction and discharge of gas. It is important to note that the water used in the pump may heat up during operation, so regular cooling and replenishment with fresh water is essential. Ideally, the water should be at around 15°C for optimal performance.

In cases where the gas being pumped is exhaust gas, a water tank is often connected to the exhaust line. This allows the gas and some of the water to mix and separate in the tank. The gas then exits through the outlet pipe, while the water is returned to the pump via a return line. If the system runs for extended periods, the water may become warm, requiring additional cold water to be introduced into the tank to maintain efficiency.
