MCA series

Product catalog summary

Description: MCA recessed impeller torque flow pumps are designed for handling viscous and pasty liquids with suspended solids, thanks to their unique impeller shape and recessed position in the casing. This design minimizes the risk of clogging.

Main Features:

Impeller: Open type with radial blades and back vanes to balance axial thrust and pressure.
Casing: Volute type with end suction and top discharge nozzles, flanges conforming to UNI, EN, DIN, and JIS standards.
Shaft Sealing: Standard mechanical seal with options for soft packing and double mechanical seals for hazardous liquids.
Materials: Standard construction in cast iron, carbon steel, and stainless steel, with other materials available on request.

Applications: Suitable for sewage treatment plants, paper, food, sugar industries, and any application involving liquids with suspended solids.

Performances:

Capacity: Up to 500 m³/h
Total Dynamic Head: Up to 100 meters
Speed: 750 to 3500 rpm

Working Principle: The impeller's special shape and position allow solid particles to pass through the casing without direct contact with the impeller.

Main Versions: Available in vertical close-coupled, close-coupled, and bare shaft versions.

Technical Specifications: Detailed dimensions and performance charts are provided, including flange dimensions and pump weights for various models.

Additional Information: Operating diagrams at 60 Hz are available upon request, and Atex certification can be provided.

La particolare forma della girante e la sua posizione arretrata rispetto alla voluta fanno sì che le particelle solide in sospensione attraversino il corpo senza toccare la girante.
