RECESSED IMPELLER TORQUE FLOW PUMPS
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.
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 NP 10 according to UNI-EN-DIN-JIS- standards.
Shaft sealing: basic pump version is mechanically sealed but soft packing with optional external flushing with clean fluid can be fitted. In case of dangerous liquids pumps can be provided with double mechanical seals completed with barrier system. 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.
