Description
Main Applications
– Waterworks
– Desalination plants
– Pressure boosting
– Water transport
– Service water and cooling water for power stations and industry
– Irrigation pumping stations
– Drainage pumping stations
– Fire-fighting systems
– Shipbuilding
– District heating systems and district cooling systems -
Advantages
– Low maintenance costs:
- – Fast and easy to install thanks to self-centring components (upper casing part, rotor, casing cover)
– Materials resistant to corrosion and abrasion
– Smooth operation with low vibration levels
– Replacement and spare parts fit several pump sizes– Long service life:
- – Sealed and dry shaft
– Short bearing distances and a short shaft
– Optional impeller wear rings
– Replaceable shaft protecting sleeve– High operating reliability:
- – Rigid shaft without threads between the bearings
– Generously sized bearings (Lh10 = 100,000 hours)
– Reliable sealing thanks to solid casing split flange
– Double-entry impeller for axial thrust balancing
– Double volute design– High flexibility:
- – Drive can be positioned to the left or right of the pump
– Shaft sealed by gland packing or mechanical seals
– Various horizontal and vertical installation options
– Flanges to DIN or ASME– Excellent efficiencies and NPSH values:
- – Computer-optimised impellers
– Large impeller inlet diameters for optimum suction behaviour
– Cost-effective replacing of casing and impeller wear rings
– Vortex-free intake elbow with low energy losses
– Impeller trimmed to match the specified duty point
– Several hydraulic systems per pump size -
