Description
Application
Aggressive, plus abrasive and corrosive liquids and slurries such
as e.g. heavily contaminated sulphur , phosphate mashes, titanium
dioxide slurries, copper digestion acids, crude tar, and liquids
sensitive to local heating from sleeve bearings
Technical data
Size: DN *2 - DN **0
Delivery rate: Qmax. = **0 m3/h
Delivery head: Hmax. = *0 m
Temperature: - **0 °C to + **0 °C

Design features
- Heavy duty chemical version with double volute casing
- Closed impeller with front and back vanes
- Extended shaft bearing arrangement with widely spaced
anti-friction bearings
- No sleeve bearings in the product being pumped, so safe from dry
running
- Shaft column separate from discharge pipe
- Pressure relieved shaft gland thanks to twin tube design
- Low speeds of flow reduce corrosion / abrasion
Sealings
Shaft sealing with stuffing box or packing ring. The sealing is not
in contact with the liquid; rising fluid in shaft pipe runs through
overflow holes back into container.
