The ETA low-pressure centrifugal pump built by KSB considers fully the recommendations of DIN 24255 with regard to main dimensions and rated capacities. By the adaption to the standardised water pump and utilising the meccano system, the ETA series provides economic advantages for plant designers, plant manufacturers and users.

Fields of Application
General water supply for municipalities, industry and agriculture; for irrigation and drainage or pumping of sea water, brines, Iyes and condensate; circulation of hot water, cooling water and oil; for blending and loading duties, etc.

Design
Horizontal single-stage, single-flow centrifugal pump with volute casing flanged onto the bearing pedestal. Axial suction nozzle and radial discharge nozzle vertically upwards, overhung radial flow impeller, shaft protecting sleeves of 316 stainless steel.

Shaft Seal
Uncooled soft-packed stuffing box up to 110°C, or cooled softpacked stuffing box over 110°C, up to 160°C. Uncooled mechanical seals up to 140°C max. may be fitted.

Drive
Direct drive by an electric motor, an internal combustion engine or turbine, via a flexible coupling. In special cases drive is also possible via a gear box, a hydraulic gear coupling, or belt drive (overhung or via a jackshaft). If a spacer type coupling is used, the complete pump rotor can be withdrawn towards the motor end, without having to remove the motor or to disconnect the piping from the pump casing.

Bearings
Axial and radial location by two oil lubricated deep groove ball bearings in the bearing pedestal. Grease lubricated bearings are available as an optional extra.
