Design

• Horizontal or verticalmultistage centrifugal pump in ring section design, as long-coupled (baseplatemounted) or close-coupled unit.
• Axial or radial suction nozzle. Radial suction and discharge nozzle can be turned in multiples of 90?.
• Flanges to EN, DIN and ANSI (bolt holes, flange face)
• Closed radial impellers, from pump size 50 upwards first stage with suction impeller to improve the NPSH value.
• Bearings/Lubrication
• Drive side: rolling element bearings
• Suction side: plain or rolling element bearings, depending on installation type
• Lubrication: Rolling element bearings grease lubricated, oil lubrication possible Plain bearings are product lubricated.

Shaft seal

• Standardized mechanical seal, uncooled or cooled, single-acting or double-acting.
• Cartridge seals possible.
• Uncooled gland packing with or without barrier liquid.
