C3) DEFINITION OF TECHNICAL TERMS Centrifugal Submersible Pump: A pump and its electric motor together in a protective housing which permits the unit to operate under water. Centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. Centrifugal pumps are the most common type of pump used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward or axially into a diffuser or volute chamber, from where it exits into the downstream piping system. Centrifugal pumps are typically used for large discharge through smaller heads.

Head—(1) A measure of the energy possessed by water at a given location in the water system expressed in feet; (2) a measure of the pressure or force exerted by water expressed in feet. Velocity Head—A measurement of the amount of energy in water due to its velocity or motion. Pressure Head—A measurement of the amount of energy in water due to water pressure. Efficiency—A ratio of total energy output to the total energy input expressed as a percent. Priming—The action of starting the flow in a pump or siphon. With a centrifugal pump, this involves filling the pump casing and suction pipe with water. Impeller: The moving element in a pump that drives the fluid.The bladed member of the rotating assembly of the pump which applies the principal force to the liquid being pumped

Backwash: The process of flow reversal to clean a filter and to restore it to the normal clean condition for filtering with a minimum resistance to flow through the media. Cavitation: A condition that occurs in pumps when the water/liquid entering the pump is changed from a liquid state to a gaseous state and back to liquid that is generally caused by too high of flow rate or from pipe that is too small for the flow rate. The formation of vapor bubbles in areas of low pressure in a liquid. Cavitation damage: The pitting or wearing away of a solid surface caused by the collapse of vapor bubbles created by low pressure prior to the damage. Centrifugal Pump: a type of kinetic energy pump using centrifugal force(slinging motion) to accomplish it's work. A pump containing a rotation impeller or rotating vanes mounted on a shaft in a casing and turned by a power source. The rotating impeller uses centrifugal force to deliver water in a steady stream.

http://en.wikipedia.org/wiki/Volute

Dead head: Operating point on the curve where unit is pumping zero GPM - also known as Shut-off Head. Diffuser: Operating point on the curve where unit is pumping zero GPM - also known as Shut-off Head. Discharge: Where the water exits the pump Discharge Head: The total head, including static head and friction head, on the discharge side of the pump. Effluent: The output stream exiting the system, filter or other device - often the waste stream Explosion proof: A type of motor enclosure that will prevent sparks generated by the motor from reaching the atmosphere outside of the motor enclosure. As a general rule our company does not sell this kind of motor. Flange: A device used to couple to a pipe on the suction or discharge of a pump Nozzle: An ejector part/device that increases the velocity of the liquid flowing through it by creating a partial vacuum at it's throat. Atmospheric pressure causes the increase in velocity. NPSH: Net Positive Suction Head. There are two types of NPSH. NPSHR is the amount of head required by the pump to keep the liquid being pumped in a liquid state. The only way NPSHR can be changed is by changing the pumps' rotational speed or its impeller diameter. NPSHA is the amount of head available to the pump to overcome the NPSHR. NPSHA should be a larger number than NPSHR. NPSHA is affected by atmospheric pressure changes, altitude, pipe and fitting sizes, and elevation to the liquid being pumped. Operating Pressure: The manufacturer's specified range of pressure expressed in pounds per square inch (PSI) in which a water processing device or water system is designed to function. Pressure Differential: The difference is pressure between two parts of a hydraulic system (influent and effluent of a filter, suction and discharge of a pump, the up and down-stream sides of a venturi or orifice). Pump Strainer: A device, placed on the suction side of a pump, which contains a removable strainer basket designed to trap debris in the waterflow with a minimum of flow restriction Pumping Level: The lowest water level reached during pumping operation.



page: 8 of 81

Rated pressure: That pressure that is equal to or less than the designed pressure and appears on the dataplate of the equipment Rate of flow: The measurement of the volume of flow per unit of time (m3/s) Recirculating system: The entire system including the suction piping, pump, strainer, filter, face piping and return piping. Self Priming: A pump designed to have the ability to prime itself automatically, after being initially filled, when operating under a suction lift; to free itself of entrained gas without losing prime; and to continue normal pumping operation without attention. Service Factor: A factor indicating the degree to which an electric motor can be operated over the specified horsepower without danger of overloading or failure. Service Pressure: The range of pressure in the pressure tank during the pumping cycle, usually expressed in pounds per square inch gauge (P.S.I.G.). Setting: The vertical distance from the level at which the discharge pipe leaves the well to the bottom of the pump or jet assembly in the well. Shut off head: The head created by a pump that is running against a closed discharge. Static Head: The vertical distance between the free level of the source of the supply and the point of free discharge, or to the level of the free surface of the discharged water. Suction: Where the water enters the pump Suction Head: The total head on the suction side of the pump, including suction lift and friction head. TDH: Total Dynamic Head TDSL: Total Dynamic Suction Lift TEFC: Totally Enclosed Fan Cooled - a type of motor enclosure



page: 9 of 81

Total Discharge Head: The total pressure or head the pump must develop on the discharge side. It is the sum of THE ELEVATION, THE SERVICE PRESSURE, and THE FRICTION LOSS. Of course, all of these measurements must be expressed in the same units, usually feet of head, before adding them together Vacuum: Negative pressure; a region in a pump or a pipe that is below atmospheric pressure Venturi: A cylindrical tube that gradually increases in size. When used in conjunction with a nozzle, it converts the velocity of the liquid being pumped to pressure. Volute Casing: A pump housing that is spiral or scroll shaped where the suction and discharge pipes screw into the unit. Watts: A measurement of electrical power where watts = volts x amps. One watt is the rate of energy expended when a steady current of one amp flows under a pressure of one volt. 1HP = 746 Watts. Wastewater Wastewater is "used" water, the water leftover after its use in numerous application such as industrial, agricultural, municipal, domestic and on

AHS MRW 00 ITY-MS100: PIPING SPECIFICATION

3 GENERAL DESCRIPTION OF THE DOMESTIC SEWAGE SYSTEM

Domestic sewage from the sanitary facilities of the administration and servicebuilding, the power house, the substation control building and the service area willbe collected in the domestic sewage tank at EL. 241,500 m. Sludge and filterbackwash water originating from the drinking water system will also be directed intothis tank.

Two submergible wastewater pumps (one duty one stand by) of at least 25m³/hcapacity transfer the wastewater via a pressure pipe to the outdoor domesticsewage network at the service area. From this point, the effluents will be directed bygravity to the sewage treatment plant.

The main components of the domestic sewage disposal system are:

- Domestic sewage tank

- Submergible domestic sewage pumps

- Domestic sewage pressure pipe

- Flushing connections

4 SYSTEMS MANAGEMENT AND OPERATION PRINCIPLES

4.1 DOMESTIC SEWAGE TANK

The domestic sewage tank (00SEO001BA) is a concrete basin integrated into theservice and administration building at El. 241.5. It is accessible via a manhole fromEl. 247.600.

The usable volume is 20 m³.

It is equipped with

- Support, guiding rope and pressure pipe to install two submergible sewagepumps. The pumps are accessible by a manhole from El. 247.6.

- A basket with a mesh size equal to the free passage of the pump (>75mm) at theinlet, accessible by the manhole from El. 247.6. This is only a safety device toprotect the pumps from extraordinary big parts, which are normally not expectedin the network

- a vent pipe going outside the building

A slight slope at the bottom of about 4% will direct domestic sewage to thesubmergible pumps.

4.2 DOMESTIC SEWAGE PUMPS

Two pumps 00 SEO 001PO and 00 SEO 002PO are installed as domestic sewagepumps to transfer domestic sewage from the domestic sewage tank 00 SEO 001 BAto the outdoor sewage network.

These are submergible centrifugal pumps specially designed for wastewater. Theyare placed inside the domestic sewage tank.

The pumps are equipped with special impellers allowing a free passage of at least75 mm.

This enables to do without strainers or rakes, which would require maintenance.



page: 45 of 81

AA M-1145-A40215.6/A

The pumps are connected to the pressure pipe using a specially designed bend.The weight of the pump acts as a seal between the pump and the bend. Formaintenance, each pump can be removed and repositioned without emptying thedomestic sewage tank.

One pump is working in normal operation mode and the other pump is working instand-by operation mode. The permutation of the pump is automatic, while thepumps electric supply is ensured from the auxiliary board 20LKA001TB.

- A low level detector 00SEP001SN detects a low level in the tank. The pump inoperation is stopped by the main auxiliaries controller 20KKM001AR.

- A high level detector 00SEO002SN detects a high level in the tank. The normalpump is started by the main auxiliaries controller 20KKM001AR.

- A very high level detector 00SEP003SN detects a very high level in the tank. Analarm is transmitted to the control room and both pumps are started by the mainauxiliaries controller 20KKM001AR.

The following table provides a summary of the main operation principles:

Sensor identification Automatic consequences

00SEP003N↑ : Start of both pumps by thecontroller 20KKM001AR, alarm

00SEP002SN↑ : Start of one pump by thecontroller 20KKM001AR

00SEP001SN↓ : Stop of the pumps in operation bythe controller 20KKM001AR

Note : ↑ represents a level rising in the tank

↓ represents a level decreasing in the tank.

Operating volumes (between start and stop) are defined for operating sequencescompatible with the maximum number of start/stop of pumps. Final levels shall bedefined after detailed calculation taking into account minimum level and pumpcurves to be given by supplier.

At the outlet of the two pumps 00SEO001PO and 00SEP002PO, two manometers,respectively 00SEP001LP and 00SEP002LP, allow the local verification of thepressure levels.

Two pressure logical sensors, respectively 00SEP001SP and 00SEP002SP, ensurethe hydraulic supervision of the flow presence at the outlet of the pumps.

The pumps 00 SEO 001 PO and 00 SEO 002 PO can be isolated for maintenancepurpose respectively by the valve 002 VE as well as 004 VE. Each of these valves isnormally open.



page: 46 of 81

AA M-1145-A40215.7/A

Two non-return valves 001 VE and 003 VE prevent respectively counter flows on thepumps 00 SEO 001PO and 00 SEO 002 PO.

4.3 DOMESTIC SEWAGE PIPING

Domestic sewage piping will either be PVC or cast iron according to pipingspecification AHS MRW00 ITY MS 100.

The piping shall have continuous slope as far as possible. If high points or lowpoints cannot be avoided, venting valves or draining valves will be installed at suchlocations.

In order to avoid sedimentation during stand still, the pipe diameter will be selectedto assure a minimum velocity of 0,8 m/s.

4.4 FLUSHING CONNECTIONS

A drinking water tap ND 50 with a hose connection and a hose is installed near thepumps. Flushing connections with ND 50 hose connections will be supplied toenable flushing each pump backwards as well as the pressure pipe in case ofblockage or prior to dismantling of the system.

4.5 VALVES

All valves used in the domestic sewage system will be gate valves to avoid anyobstacles that may lead to a blockage.

All check valves will also be of “free flow” type without restrictions or obstacles whenopen.

5 SYSTEM CONTROL PRINCIPLES

5.1.1 Remote control

This system is controlled from the main auxiliaries controller 20KKM001AR.

The selector switches for the pumps 00SEO001PO/00SEO002PO on the auxiliaryboard 20LKA001TB must be set to ‘Remote’.

Based on levels in the tank, detected by level sensors, the sewage control box00SEO001CR sends a starting order to the pump to be started.



page: 47 of 81

AA M-1145-A40215.8/A

In case the pump to be started is in electrical fault, detected on the auxiliary board20LKA001TB, or in hydraulic fault, detected after a time delay by the pressurelogical sensors, the pump to be started is stopped. This pump is then set to ‘fault’mode and the other pump is started in replacement.

5.1.2 Maintenance and manual control

The pumps are controlled from the auxiliary board 20LKA001TB.

The selector switches for the pumps 00SEO001PO/00SEO002PO on the auxiliaryboard 20LKA001TB must be set to ‘Local’ and all operation must be done throughthis auxiliary board.

The pumps electrical safety devices are in operation.

All operations are done manually under plant personnel responsibility.

Regularly in order to maintain the pumps in the optimal condition, all pumps must beset to ‘Local’ mode, and each of them must be successfully started from the auxiliaryboard 20LKA001TB.

5.2 ELECTRICAL INTERFACES TO OTHER SYSTEMS

Domestic sewage tank 00SEO003BA very high level sensor (00SEO003SN) willinterlock sludge discharge and filter backwashing of the drinking water system.

7.2 Service/Inspection

The following points must be observed to ensure reliableoperation:

This work must only be carried out by experienced personnel!

Item Maintenance tasks Maintenance tobe carried outat followingintervals

7.2.1 Insulation resistance check7.2.2 Visual inspection of electric cables every7.2.3 Check of monitoring equipment 4,000 hours7.2.4 Oil change but at least7.2.5 Bearings and lubrication once a year7.2.6 Visual check of lifting chain / rope

General overhaul every 5 years

7.2.1 Insulation resistance check

The insulation resistance of the motor winding has to bechecked every 4,000 hours but at least once a year duringgeneral maintenance.

Measurements should be taken at the cable ends (disconnected atthe starting panel). The measurement should be t aken by us ing amegger.– Measuring voltage: max 1,000 V d.c. voltage

The insulation resistance of the motor winding with cable ends tiedtogether must not be l ess than 5 m egohm. I f measurements areless, then cable and motor must be checked separately. During themeasurement proc edure t he s upply c able m ust be disconnectedfrom the motor.

The measurements to be taken are:

a) Winding against earth- All winding ends connected with each other

b) Winding temperature sensor against earth- All cable ends of the winding temperature sensors should be

connected to one another and all winding ends be connected to earth

Ambient and pumped liquid temperature

If the insulation resistance for the electric supply cable is less than5 megohm, this indicates damage and needs replacement.

Low reading of the i nsulation res istance val ues of t he m otorindicates that there i s a f ault i n t he w inding. I f t his i s t he c ase,contact ei ther t he m anufacturer or t he neares t K SBAgent/Distributor.

7.2.2 Inspection of the electric cable

- Visual inspection of the electric cable.

Whenever the pump is inspected, the electrical supply cables should also be checked with regard to damage such as cracks or bubbles, due to either mechanical or chemical causes.If such damage is detected, then all electric cables must be replaced.

- Checking the protection cable. Measurement of the resistancebetween the cores should be R < 1 Ohm.

7.2.3 Checking the monitoring equipment

The performance tests should form part of general periodicmaintenance work, carried out every 4,000 hours or at leastannually.

a) Temperature switch – Check resistance between the connection ends 21 and 22: R < 1 Ω

b) PTC–resistor sensor– resistance measuring –resistance between connection ends 10 and 11:10 Ω < R < 750 Ω

If t he gi ven t olerances are ex ceeded, di sconnect the electricsupply/control c able at t he uni t and c heck agai n di rectly at t heterminals of t he uni t. I f t olerances are exceeded here, too, thewinding must be replaced.

c) Moisture protection electrode - Insulation resistance check

The motor area is being monitored by a l eakage detector which isfitted into the motor area. It is fitted as standard.

Instructions rel ating t o perf ormance and technical data can befound in Appendix ”Moisture protection monitoring”.

The moisture monitoring el ectrode i s ok ay i f t he i nsulationresistance measured at t he el ectrode i s > 1 M Ω. Lower val uesindicate moisture or even intrusion of water into the motor. In suchcases, the motor needs to be opened and overhauled.

A NEW MOISTURE PROTECTION ELECTRODE MUST BEFITTED IN THE EVENT OF DAMAGE.

7.2.4 Oil change

The oil c hamber of our s ubmersible pum p has been filled withenvironmentally friendly, non-toxic paraffin oil of medical quality onthe pump end.

However, the oil should be changed after 4,000 operatinghours, but at least annually.

Pumped liquid might enter the oil chamber whenit i s w arm af ter operat ion, w hich c an cause apressure rise within the chamber. It is, therefore,advisable t o c over t he f illing plug 903 (with acloth) duri ng t he openi ng proc ess t o avoi d hotliquid (squirting out) escaping.

Procedure(Appendix 1 - ”General pump arrangement”).

Erect t he pum p as s hown i n Fig. 8 and put a s uitable c ontainerunder t he plug. Rem ove f illing plug 903.03 with gasket 411 anddrain the oil.

The oi l i s l ight i n c olour and t ransparent in appearance. Slightdiscolouring, caused by running in of new mechanical seal or smallleakage of dirt via the pumped media will have no adv erse ef fect.Severe c ontamination of t he oi l by t he pum p media, however,indicates dam aged m echanical s eals. I n t his c ase, repl ace t hemechanical seal.

7.5 Re-assembly

7.5.1 General instructions

Assembly of the pump must be c arried out in accordance with thecurrent m echanical engi neering regul ations. A ll part s which weredismantled m ust be c leaned and t ested w ith regard to wear.Damaged or w orn part s m ust be replaced by usingmanufacturer‘s spare parts. Ensure that al l sealing surfaces areclean and the O-rings or flat seals fit perfectly. We recommend theuse of O-ri ngs/seals at al l t imes.O-rings m ade from continuousstrips which were glued together must not be used.

Assembly of the pump takes place in reverse order of dismantling.The drawing combined w ith t he i ndividual part s i ndex s hould beused as a guide. All screws must be t ightened during assembly asoutlined in the instructions. General instructions in this respect areoutlined in the table below ”bolt tightening torque” and specialpoints are stated in the installation instructions.

7.5.2 Special points relating to components for re-assembly

7.5.2.1 Mechanical sealIn principle, we recommend to use new manufacturer‘s spare partsfor mechanical seals. In this respect it should be noted:

To ac hieve perf ect perf ormance, i t i s i mportant t o ens ure t hat allparts are immaculately clean and that greatest care is taken duringthe f itting of t he m echanical s eal. P rotectors of the movingsurfaces must not be rem oved unt il immediately before fitting thepart. The s urface of t he s haft m ust be perf ectly clean andundamaged.

In principle to assist with the fitting of the bellows mechanical seal,the i nside of t he bel lows t o avoid any dam age to the mechanicalseal should be wetted with soapy water (do not use oil).

Attention: Fitting of t he bel lows m echanical s eal at themotor end.

To avoid damage t o t he rubber bel lows by a k eyway or s haftrecess, the shaft stub should be c overed w ith a t hin s heet of f oil(approx. 0.1...0.3 mm thick). Push the rotating uni t over f oil coverand place into fitting position. Then remove the foil.

7.5.2.2 Impeller assembly

Instructions and proc edures are out lined i n Appendix ”Impellerdismantling/fitting”. Paragraph 7.4.3 outlines appropriate size.

7.5.2.2.1 KRT D-Wear plate
