2. Product Features and Advantages
A. Features of the side channel pump:
- Self-priming capability and ability to handle gas-liquid mixtures;
- Extremely low NPSHr, avoiding cavitation even under full-load operation;
- Gas conveying capability, ensuring continuous operation when the medium vaporizes;
- Steep performance curve, extending the service life of the installed equipment;
- Shaft seal and material selection that meet emission standards;
- Quiet operation — one of the quietest pumps on the market.
B. Advantages of the side channel pump over a conventional centrifugal pump:
- Thanks to the special impeller design, the pump generates a high head at low flow rate — a typical low-flow, high-head pump;
- Under low-flow, high-head conditions its efficiency is 6-10 times that of a conventional centrifugal pump;
- The lowest NPSHr of any centrifugal pump worldwide, avoiding cavitation under full-load operation;
- Gas conveying capability, ensuring continuous operation when the medium vaporizes;
- Strong self-priming ability, suitable for suction-lift applications;
- For flammable, explosive or toxic media, a magnetically coupled side channel pump can be supplied;
- Modular hydraulic design.
