➢ All electric motors are suited for connection to frequency control.

2.6 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.

2.6.1 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.

2.6.2 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 m 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;

/h, a maximum shaft

CL-CBH/EN (1901) 7.6 General 15

Page 18

‘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 m

/h;

‘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.

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.

2.6.3 Energy Efficient Pump Selection

In selecting the pump, care should be taken to ensure that the duty point required is as close as possible to the pump’s Best Efficiency Point (BEP). Different heads and flows can be achieved by changing the diameter of the impeller and thereby eliminating unnecessary energy loss.

The same pump can be offered at different motor speeds to allow the pump to be used over a much wider range of duties. For instance, changing from 4-pole motor to 2-pole motor will enable the same pump to deliver twice as much peak flow at 4 times the head.

Variable speed drives allow the pump to operate efficiently over a wide range of speeds hence duties in an energy efficient manner. They are particularly useful in systems where is a variation in required flow.

A very useful tool for energy efficient pump selection is the downloadable software program “Hydraulic Investigator 2” from the SPXFLOW website.

Hydraulic Investigator is the selection guide for centrifugal pumps and search by pump family and pump type starting from entering required capacity and head. Further refine the pump curves to find the pump that meets your specification.

The default setting of applicable pump types is prioritized on highest efficiency. In the standard automated selection procedure the optimum (trimmed) impeller diameter is calculated already, where applicable. Manually the rotating speed can be adjusted as well when a variable speed drive is preferred.

Example:

Curve 1: performance at maximum impeller diameter and 2960 rpm;

Curve 2: performance at required duty point (180 m

power consumption 18,42 kW;

Curve 4: performance at required duty point with maximum diameter and reduced

rotating speed (2812 rpm), power consumption 18,21 kW.

5 Product type and size identifier are marked on the rating plate. An example and

explanation is given in paragraph 2.6.5 "Product information" of this document.

6 The hydraulic pump efficiency of the pump with trimmed impeller diameter is marked

on the rating plate, either the efficiency value [xx.x]% or [-.-]%.

7 Pump curves, including efficiency characteristics, are published in the downloadable

software program “Hydraulic Investigator 2” from the SPXFLOW website. For downloading “Hydraulic Investigator 2” go to http://www.spxflow.com/en/johnsonpump/resources/hydraulic-investigator/ The pump curve for the delivered pump is part of the related customer order documentation package separate from this document.

8 The efficiency of a pump with a trimmed impeller is usually lower than that of a pump

with the full impeller diameter. The 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.

9 The 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.

10 Information relevant for disassembly, recycling or disposal at end-of-life is described

in paragraph 2.7 "Re-use", paragraph 2.8 "Scrapping" and chapter 7 "Disassembly and assembly".

3Installation

3.1 Safety

• Read this manual carefully before installing the pump and putting it into operation. Non-observance of these instructions may cause serious damage to the pump that is not covered by our guarantee terms. Follow the instructions step by step.

• Depending on the design the pumps are suitable for liquids with a temperature of up to 140°C. When installing the pump unit to work at 65°C and above the user should ensure that appropriate protection measures and warnings are fitted to prevent contact with the hot pump parts.

3.2 General

• The area in which the pump unit is to be placed should be adequately ventilated. A too high ambient temperature and air humidity, as well as a dusty environment may have a negative effect on the functioning of the electric motor.

• The foundation for a CBH pump must be hard, level and flat.

• The cooling air inlet of the motor should be positioned in such a way that unobstructed air supply is ensured.

• Make sure that the system pressure is always below the maximum allowable operational pressure. For exact values see paragraph 10.1 "Technical data pumps".

• If the pumped liquid is harmful to men or the environment, take appropriate measures to drain the pump safely. Possible leakage liquid from the mechanical seal should also be discharged safely.

3.3 Accessories

• In case the pump is provided with an isolation, special attention has to be paid To temperature limits of shaft seal and bearing.

3.4 Piping

As regards the piping and connecting points of the pump attention should be paid to the following:

• The piping to the suction and delivery connections must fit exactly and must not be subject to stress during operation. For the maximum allowable forces and moments on the pump flanges of a CBH pump see paragraph 10.8 "Permitted forces and torques on the flanges for CombiBlocHorti".

• Preferably a CL pump should be mounted in the piping in such a way that the direction of flow is vertical, so as to prevent air from remaining in the pump. Air in the pump may cause damage to the mechanical seal!

• Make sure that the system has one or more draining apertures. Also, it should be possible to bleed or de-aerate the system, preferably directly above the pump.

CL-CBH/EN (1901) 7.6 Installation 23

Page 26

• If necessary mount valves before and after the pump. Do not use quick-acting valves, as they may cause high pressure impulses in the pump and the piping (water hammer pressure).

• Before installing the pump, all piping should be flushed, to eliminate all dirt, grease or possible other particles.

3.5 Installing a CL pump

The pump can be mounted in both horizontal and vertical piping. However, the electric motor should always be in horizontal position.

When installing this type of pump, proceed as follows:

1 Make sure the piping is supported before and after the pump (brackets).

2 The arrow on the pump casing shows the exact position of the suction and delivery

flange.

3 Check the position of the terminal box on the electric motor in relation to the position

of the pump in the piping. If this position is not correct, the stator should be rotated. See paragraph 7.6.1 "Electric motor stator".

4 Mount the flange gaskets and place the pump between the flanges of the piping.

5 Insert the fastening bolts and nuts for each flange and tighten them crosswise.

3.6 Installing a CBH pump

When installing this type of pump, proceed as follows:

1 Mount the flange gaskets and place the pump between the flanges of the piping.

2 In case of permanent arrangement of the pump, level the pump on the foundation by

means of shims.

3 Then carefully tighten the nuts of the foundation bolts.

4 Insert the fastening bolts and nuts for each flange and tighten them crosswise.

3.7 Connecting the electric motor

 The electric motor must be connected to the mains by an approved

electrician, according to the locally prevailing regulations of the electricity company.

• Refer to the instruction manual belonging to the electric motor.

• If possible, mount a working switch as close as possible to the pump.

24 Installation CL-CBH/EN (1901) 7.6

Page 27

CombiLine-CombiBlocHorti

4 Commissioning

4.1 Inspection

Prior to commissioning the pump:

• Check if the fuses have been installed.

• Check if the impeller can rotate freely. Do this by rotating the shaft end with a screwdriver through the hole in the protective cover of the electric motor.

• Check if the suction and delivery connections have been mounted correctly.

• Check the sense of rotation.

4.2 Commissioning

Proceed as follows, both for commissioning and after the pump is put back into operation after repairs:

1 Open the valves. If there still is hot water in the pipes, open the valves gradually to

prevent pressure impulses or sudden changes of temperature, which would cause serious damage to the pump.

2 Fill the system with liquid until the correct pressure is reached.

3 Bleed the system.

4 Switch on the pump.

4.3 Pump in operation

When the pump is in operation, pay attention to the following:

! The pump should never run dry!

• Never use a stop valve in the suction line to control pump output. The stop valve should always be fully opened during operation.

• Check whether the pressure difference between suction and delivery side corresponds with the specifications of the pump's duty point.

• Check whether the absolute inlet pressure is sufficient, to prevent vaporization in the pump. Vaporization may cause cavitation.

! Cavitation should always be prevented since it causes serious damage to the

pump!

5 Maintenance

! Flawed maintenance will result in shorter lifespan, possible break down and

in any event loss of warranty.

5.1 Bearings

Both motor bearings have been greased for their lifetime and require no maintenance.

5.2 Mechanical seal

A mechanical seal generally requires no maintenance, however, it should never be allowed to run dry. If there are no problems, do not dismantle the mechanical seal. As

the seal faces have run in on one another dismantling usually implicates replacement of the mechanical seal. If a mechanical seal shows any leakage it has to be replaced.

5.3 Environmental influences

• When a unit is out of operation and there is a risk of freezing, it is recommended to drain the unit.

• Check motor for accumulation of dust or dirt, which might influence motor temperature.

• The standard protection class of the electric motor is IP 55, this means that it is 'spray-water proof'.

! Never spray water on hot pump elements! They may burst and hot water may

flow out.

5.4 Noise

The noise produced by a pump depends to a great extent on the operation conditions. The values are stated in paragraph 10.6 "Noise data".

If a pump starts making excessive noise, this may point to certain problems with the pump unit. A crackling noise can indicate cavitation or excessive motor noise can indicate deterioration of the bearings.

5.5 Motor

Check motor specifications for start-stop frequency.

CL-CBH/EN (1901) 7.6 Maintenance 27

Page 30

5.6 Failures

1 If the pump shows problems, the cause may be elsewhere in the system. First check

whether this is the case.

2 If you are sure the problem is within the pump, try to determine the cause. See

chapter 6 "Faults". Then take the necessary measures.

3 See chapter 7 "Disassembly and assembly" in case repair is necessary.

 Always switch off the pump and close the valves before trying to determine a

failure!

! First of all try to find what caused the failure. In case of electric failure, the

cause may be in the cabling. In that case consult a approved electrician!

7 Disassembly and assembly

7.1 General

7.1.1 Special tools

Special tools can make certain operations easier. The instructions will indicate when these tools should be used.

7.1.2 Back Pull Out-unit

The pump is designed with a Back Pull Out-system. This means that in case of repairs, the pump casing does not have to be removed from the piping (unless the fault is in the pump casing itself).

7.2 Precautions

Before the pump can be repaired it first has to be removed from the system. Take the following steps:

7.2.1 Switch off the electricity supply

1 Disconnect the electricity supply to the pump by setting the pump switch on the

switchboard or, if available, the operation switch, to "O".

2 Remove the fuses.

3 Place a warning plate at the switchboard cabinet.

7.2.2 Support of the piping

If the entire pump has to be removed, you have to make sure that the piping is properly supported. If this is not so, you should first support and bracket the piping.

7.2.3 Liquid draining

1 Close all valves wherever necessary.

2 Drain the system to the extent that there is no liquid left in the pump.

 Be careful not to touch the liquid, it may still be hot!

3 A pump that is used for heating should be left to cool down first.

7.9 Assembling the pump

The item numbers used refer to the parts lists and drawings of chapter 9 "Parts".

7.9.1 Mechanical seal

! A mechanical seal is a vulnerable precision part. Leave the mechanical seal

inside its original packaging until you mount it. Make sure the work site is free from dust and that the parts and tools are clean. Remove possible paint on parts. Never put the sliding rings down on the sliding surfaces.

1 If applicable screw the studs (0950) into the lantern piece (0110).

2 Grease the seat of the static ring of the mechanical seal with Molycote 111.

3 Place the lantern piece (0110) flat on the work surface and press the static ring

(1220-A) of the mechanical seal inside. If necessary use a plastic pressure piece.

! DO NOT hammer the ring inside!

4 Fit the lantern piece to the electric motor and proceed with mounting the mechanical

seal.

! Be careful not to damage the centring rim of the motor flange.

If the pump is not fixed straight to the lantern piece the bearings and mechanical seal will be damaged.

5 For pumps provided with a shaft sleeve: Grease the shaft with Molycote 111 and

mount the shaft sleeve (1200) onto the shaft end.

6 Put some soap suds on the bellows and slide the rotating part of the mechanical seal

(1220-B) onto the shaft sleeve or the shaft, until the seal faces of the two seal components just touch each other.

! At that moment, stop pushing the bellows against the spring tension! After the

impeller has been mounted, the mechanical seal will be at the right pre-load.

7.9.2 Impeller

1 Place the key (1860) in the key way of the shaft.

2 For pumps provided with shaft sleeve and for CL 4/4 and CL 5/4: Grease the

impeller hub and the O-ring seat with Molycote 111 and mount the O-ring (1320).

3 Mount the impeller (0120) onto the shaft. The impeller will compress the bellows of

the mechanical seal, giving it the correct pre-load.

4 Put a drop of Loctite 243 on the thread of the cap nut (1820) and fit it onto the shaft.

CL 4/4 and CL 5/4: First place the washer (1825).

! Apply the Loctite only on the thread of the cap nut and not on other parts! It

might run in between the shaft and the impeller hub and in that case the impeller will get stuck on the shaft!

10.8 Permitted forces and torques on the flanges for CombiBlocHorti

Forces and moments acting on the pump flanges due to pipe loads can cause misalignment of the pump, deformation and overstressing of the pump casing, or overstressing of the fixing bolts between the pump and the baseplate.

The values can be applied simultaneously in all directions with positive or negative signs, or separately on each flange (suction and discharge).

Figure 26: Coordinate system.
