Product benefits
▪Improved efficiency and NPSHreq by experimentally verified
hydraulic system of impellers (vanes)
▪Low energy costs through compliance with future
requirements of Commission Regulation 547/2012
(minimum efficiency index MEI ≥ 0.4)
2) Depending on the size, pumps with bearing pedestal have integrally cast pump feet.
3) On request

▪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
▪Optimum material selection for the specific fluid handled
by a large variety of materials. Large range of materials
for many applications available as a standard.
▪Extended selection chart with additional pump sizes for
small flow rates
▪Easy to dismantle with forcing screws provided at the
interface of casing cover and bearing bracket
Product Information as per Regulation No. 547/2012 (for
Water Pumps with a Maximum Shaft Power of 150 kW)
Implementing "Ecodesign" Directive 2009/125/EC
▪Minimum efficiency index: see data sheet
▪The benchmark for most efficient water pumps is MEI ≥
0.70.
▪Year of construction: see data sheet
▪Manufacturer’s name or trade mark, commercial
registration number and place of manufacture: see data
sheet or order documentation
▪Product’s type and size identificator: see data sheet
▪Hydraulic pump efficiency (%) with trimmed impeller: see
data sheet
▪Pump performance curves, including efficiency
characteristics: see documented characteristic curve
▪The efficiency of a pump with a trimmed impeller is
usually lower than that of a pump with full impeller
diameter. Trimming of the impeller will adapt the pump
to a fixed duty point, leading to reduced energy
consumption. The minimum efficiency index (MEI) is based
on the full impeller diameter.
▪Operation of this water pump with variable duty points
may be more efficient and economic when controlled, for
example, by the use of a variable speed drive that matches
the pump duty to the system.
▪Information relevant for disassembly, recycling or disposal
at end of life: see installation/operating manual
▪Information on benchmark efficiency or benchmark
efficiency graph for MEI = 0.7 (0.4) for the pump based on
the model shown in the Figure are available at: http://

content required in this case. Please contact KSB if limits are exceeded.
6) General evaluation criteria for results of water analysis; pH value ≥ 7; chlorides content (Cl') ≤ 250 mg/kg. Chlorine (Cl2) ≤
0.6 mg/kg.
7) Treatment to VdTÜV 1466; additional requirement: O2 < 0.02 mg/l

9) No ultra-pure water! Conductivity at 25 °C: < 800 μS/cm, neutral with regard to chemical corrosion
10) The dosing system should be at least 4 m away from the pump set. The chlorine injected should not be directed straight at
the pump (will cause damage in the long term).
