Submersible motor pumps are applied whenever the duty conditions are suitable; dry-installed volute casing pumps are the ideal choice in those applications where the cost incurred by a pump failure would be in no relation to the relatively higher expense of building an adequate civil structure.

Dry-installed pumps are used as collecting pumping stations, when they are installed in a central location, because they are easily accessible for inspections and maintenance and to remedy a possible malfunction. A high degree of operating reliability and easy access for maintenance and operation are the main characteristics of a dry-installed pumping arrangement.
