Coating and preservation

Coating and preservation to KSB standard Product benefits

Product Benefits

• Improved efficiency and NPSHreq by experimentally verified hydraulic design of impellers (vanes)
• Low energy costs through compliance with Commission Regulation 547/2012 (minimum efficiency index MEI ≥ 0.4)
• Operating costs reduced by trimming the impeller diameter to match the specified duty point
• Little wear, low vibration levels and excellent smooth running characteristics thanks to good suction performance and virtually cavitation-free operation across a wide operating range
• Casing sealed reliably – even in varying operating conditions – by confined casing gasket
• Large variety of materials for perfectly matching the pump to the fluid handled. Large range of materials for many applications available as standard.
• Low-noise low-vibration motors specially designed for Etaline L. Also available as 2-pole motors.
