RECESSED IMPELLER TORQUE FLOW PUMPS

DESCRIPTION:
Thanks to the shape of the impeller and to its recessed position in the casing, MCA pumps are suitable for pumping viscous and pasty liquids containing suspended solids. 

MAIN FEATURES: 
Impeller: the impeller is of open type with radial blades. The impeller is provided with back vanes to balance the axial thrust and the pressure in the stuffing box area.

Casing: volute type with ample section end suction and top discharge nozzles. The flanges are drilled UNI or DIN NP 10.

Shaft sealing: basic pump version is mechanically sealed but soft packing with external flushing with clean fluid can be fitted. For high temperature the pump can be provided with a cooling chamber. The fitting of single or double acting mechanical seals flushed from external source by suitable media can also be possible. 

MATERIALS:
Standard constructions are in cast iron, carbon steel, stainless steels. Any other material combinations can be supplied. 

APPLICATIONS:
Sewage treatment plants, paper industry, food and sugar industry and generally to convey all liquids with suspended solids. 

PERFORMANCES:
Capacity up to 500 m3/h.
Total dynamic head up to 100 meters.
Speed from 750 to 3500 rpm. 

OPERATING SYSTEM:
The special impeller shape and its position in the back part of the casing operates in such a way that the fluid flows through the casing without touching the impeller.
