Description

Structure and Performance

Structural Features:

1. Open impeller structure, with corresponding pump casing and pump cover both equipped with replaceable wear plates;

2. The pressure chamber employs radial guide vanes combined with a ring-shaped volute, resulting in more uniform stress distribution across pressure-bearing components.

3. The modular single-face mechanical seal, supplemented by the Plan32 flushing scheme, enhances the pump’s sealing reliability and service life.

4. The large-diameter rigid shaft structure enhances pump reliability and operational stability.
