Their applications are varied: Provision of seawater for desalination systems, transports of cooling water in power stations and industrial plants, water extraction for flue gas desulphurisation, or water extraction and drainage in low-lift pumping stations. But the demands made on tubular casing pumps are invariably high. In long-term operation, they have to supply large amounts of water safely and reliably.
Tubular casing pumps can be supplied in two design variants:
1. The pull-out design is easier to service and maintain: During dismantling and re-assembly, thae entire rotor can be withdrawn for inspection and maintenance. This minimises downtime for maintenance work and reduces life cycle costs.
2. Non-pull-out design is considerably lower because a number of components can be dispensed with. This reduces both the weight of the pump and the initial costs.
