Impeller type

Closed radial impeller with multiply curved vanes

Bearings

Grease-packed radial ball bearing

Automation

Automation options:

• PumpDrive
• PumpMeter

Coating and preservation

• Coating and preservation to KSB standard AN 1897/54-09
• Pump casing without coating
• Drive lantern, intermediate piece with primer coat

Product benefits

• Maintenance-free mechanical seal ensures operating reliability
• Easy to dismantle due to back pull-out design; no need to remove the pump casing from the piping
• Optimised hydraulic components for high efficiency help reduce energy consumption
• Corrosion-resistant with all wetted parts made of stainless steel (1.4571).
• Long service life, maintenance-free with high-quality standardised mechanical seal to EN 12756
