2.1 Pump description
The CombiLineBloc is a built-in circulation pump constructed with a lantern piece and a
standard IEC electric motor with flange. That means that the medium to be pumped will
not get into the electric motor. The pump is provided with a mechanical seal with bellows
mounted on the stub shaft which is mounted directly on the motor shaft. The pump has
been designed as a monobloc pump which means that pump, lantern piece and electric
motor have been assembled to form one compact unit. Suction and delivery flange are
in-line, so the pump can easily be built into straight pipes without a foundation being
required. The pump can also be mounted with the suction bend placed on a fundation by
means of the special support device. The pumps are available in 2 speeds. The flanges
are according to EN 1092-2 (DIN 2532) PN10 or EN 1092-2 (DIN 2531) PN6.
2.2 Applications
• In general, this pump can be used for thin, clean or slightly polluted liquids. These
liquids should not affect the pump materials.
• Further details about the application possibilities of your specific pump are mentioned
in the order confirmation and/or in the data sheet enclosed with the delivery.
• Do not use the pump for purposes other than those for which it is delivered without
prior consultation with your supplier.
Using a pump in a system or under system conditions (liquid, working
pressure, temperature, etc.) for which it has not been designed may hazard
the user!

2.6 Construction
2.6.1 Design
The design is characterized by a compact construction. The pump is mounted to a
standard IEC flange motor by means of a lantern piece and a stub shaft. The pump cover
is clamped between the pump casing and the lantern piece.
The electric motors up to and including frame size 112M have B5 mounting arrangement
and the larger types have B3/B5 mounting arrangement. All vertically placed motors
have mounting arrangement V1.
2.6.2 Pump casing/impeller
• The pump casing is of the volute type. Suction and delivery flange are placed in-line
and have the same flange size.
• The specially shaped suction bend ensures low-noise functioning of the pump and
favorable NPSH values.
• The impeller is of the closed type and is mounted directly on the end of the stub shaft.
The impeller is fixed by means of a cap nut.
2.6.3 Mechanical seal
The pump is provided with a mechanical seal with mounting dimensions according to EN
12756 (L1K) (DIN 24960 (L1K)). This mechanical seal can be used up to a working
pressure of 10 bar and a temperature of 120 °C (peak values of 140 °C).
2.6.4 Bearing construction
The bearing is provided by the motor bearings. The selection of the motor-pump
combination is such that the bearings of the applied electric motors can absorb the axial
and radial forces without the bearing life being affected.
The electric motors must be provided with a fixed bearing.

2.7 Ecodesign Minimum Efficiency Requirements Water Pumps
• Directive 2005/32/EC of the European Parliament and of the Council;
• Commission regulation (EU) No 547/2012 Implementing Directive 2009/125/EC of
the European Parliament and of the Council with regard to ecodesign requirements for
water pumps.
2.7.1 Introduction
SPX Flow Technology Assen B.V. is an associate member of the HOLLAND PUMP
GROUP, an associate member of EUROPUMP, the organization of European pump
manufacturers.
Europump promotes the interest of the European pump industry with the European
institutions.
Europump welcomes the aim of the European Commission to reduce eco-impact of
products in the European Union. Europump is fully aware of the eco-impact of pumps in
Europe. For many years the ecopump initiative is one of the strategic columns in the work
of Europump. From the first of January 2013 the regulation is coming into force
concerning minimum required efficiencies of rotodynamic water pumps. The regulation
sets minimum efficiency requirements on water pumps set out under the Ecodesign
Directive for energy related products. This regulation mainly addresses manufacturers of
water pumps placing these products on the European market. But as a consequence
customers may also be affected by this regulation. This document gives necessary
information related to the coming into force of the water pump regulation EU 547/2012.
2.7.2 Implementing Directive 2009/125/EC
• Definitions:
“This Regulation establishes eco-design requirements for the placing on the market of
rotodynamic water pumps for pumping clean water, including where integrated in other
products.”
“Water pump” is the hydraulic part of a device that moves clean water by physical or
mechanical action and is of one of the following designs:
• End suction own bearing (ESOB);
• End suction close coupled (ESCC);
• End suction close coupled inline (ESCCi);
• Vertical multistage (MS-V);
• Submersible multistage (MSS);”
‘End suction water pump’ (ESOB) means a glanded single stage end suction
rotodynamic water pump designed for pressures up to 1600 kPa (16 bar), with a specific
speed ns between 6 and 80 rpm, a minimum rated flow of 6 m3/h, a maximum shaft
power of 150 kW, a maximum head of 90 m with nominal speed of 1450 rpm and a
maximum head of 140 m with nominal speed of 2900 rpm;
‘End suction close coupled water pump’ (ESCC) is an end suction water pump of which
the motor shaft is extended to become also the pump shaft;
‘End suction close coupled inline water pump’ (ESCCi) means a water pump of which
the water inlet of the pump is on the same axis as the water outlet of the pump;
‘Vertical multistage water pump’ (MS-V) means a glanded multistage (i > 1) rotodynamic
water pump in which the impellers are assembled on a vertical rotating shaft, which is
designed for pressures up to 2500 kPa (25 bar), with a nominal speed of 2900 rpm and
a maximum flow of 100 m3/h;

CLB/EN (1901) 6.6 General 17
CombiLineBloc
‘Submersible multistage water pump’ (MSS) means a multistage (i > 1) rotodynamic
water pump with a nominal outer diameter of 4” (10,16 cm) or 6” (15,24 cm) designed to
be operated in a borehole at nominal speed of 2900 rpm, at operating temperatures
within a range of 0°C and 90°C;
This Regulation shall not apply to:
1 water pumps designed specifically for pumping clean water at temperatures below -
10°C or above +120°C;
2 water pumps designed only for fire-fighting applications;
3 displacement water pumps;
4 self-priming water pumps.
• Enforcement:
In order to enforce this there will be a Minimum Efficiency Index (M.E.I.) criteria set for
the above list of pumps.
The MEI is a dimensionless figure that is derived from a complex calculation based on
the efficiencies at BEP (Best Efficiency Point), 75% BEP & 110% BEP, and the specific
speed. The range is used so that manufacturers do not take an easy option of providing
good efficiency at one point i.e. BEP.
The value ranges from 0 to 1,0 with the lower value being less efficient, this provides the
basis of eliminating the less efficient pumps starting with 0,10 in 2013 (the lowest 10%)
and 0,40 (the lowest 40%) in 2015.
The MEI value of 0,70 is classed benchmark for the most efficient pumps in the market at
the time of developing the directive.
The milestones for the MEI values are as follows;
1 1st January 2013 all pumps shall have a minimum MEI value of 0,10;
2 1st January 2015 all pumps shall have a minimum MEI value of 0,40.
The most important point of this is that unless the pumps comply then they
will not be allowed to have a CE marking.
• Part Load Performance
It is common practice that pumps spend much of their time working away from their rated
duty, and efficiency can fall off rapidly below the 50% duty point, any scheme should take
account of this real life performance. However, manufacturers need a pump efficiency
classification scheme that makes it impossible to design pumps with a steep fall off in
efficiency either side of the BEP point in order to claim a higher efficiency than would be
typical of real life operation.
• ‘House of Efficiency’
The decision scheme ‘House of Efficiency’ takes into account design and application
purposes as well as the pump minimum efficiency dependence on flow. The minimum
acceptable efficiency is therefore different for each pump type. The pass-or-fail scheme
is based on two criteria A and B.

18 General CLB/EN (1901) 6.6
Criterion A is the pass-or-fail minimum efficiency requirement at the best efficiency point
(BEP) of the pump:
Where
Criterion B is the pass-or-fail minimum efficiency requirement at part load (PL) and at
overload (OL) of the pump:
Therefore a method is devised what is called a “house of efficiency” scheme that also
requires pumps to pass efficiency thresholds at 75% and 110% of rated flow. The
advantage of this is that pumps will be penalised for poor efficiency away from rated
efficiency, hence it will take account of real life pump duties.
It should be stated that while the scheme may appear complicated at first sight, in
practice it has been easy for the manufacturers to apply the scheme to their pumps.
