C 3045

Summary

Product identification

The Flygt 3045, 50Hz is available in two main pump types:

• C-pump: A submersible pump designed for clean water, surface water, or light wastewater containing solids or fibered material. It is classified as a High head (HT) pump.
• D-pump: A submersible pump featuring vortex hydraulic, suitable for liquids containing solids and abrasive media, or light wastewater. It is classified as a Medium head (MT) pump.

Both pump types are available in:

• Non-explosion proof version: Type 3045.181
• Explosion proof version: Type 3045.091

The pump can be used in the following installation types:

• F: Free standing semi-permanent, wet well arrangement where the pump is placed on a firm surface.
• H: Semi-permanent, wet well quick connection suspended arrangement, incorporating integral non-return valve (available for C-pump only).
• P: Semi-permanent, wet well arrangement with pump installed on two guide bars with automatic connection to discharge.
• S: Portable semi-permanent, wet well arrangement with hose coupling or flange for connection to discharge pipeline.
