| General Technical Requirements of the pumps | |||||||||||
| item.No. | Item description | Technical Requirements | |||||||||
| 1 | Submersible Borehole Pump for potable water | The pump shall be designed and constructed to be suitable for pumping of potable water and shall be designed to give the specified output against all loses including those relating to pump station pipe work and valves. The pump to be supplied shall have the pump efficiency as specified in particular requirement and reliability at a given duty point. The whole pumping unit shall be capable of withstanding, without detriment, reverse rotation to a speed that would occur if the pump were to stop when the differential head was at a maximum and the delivery and/or non-return valve failed to close. The material and the pump construction will be suitable for the ground water quality characterized mainly by: § Sand content to 50 g/m3 § Low PH, minimum 5 § High co2 content up to 100g/l The submersible pumps & related accessories shall operate in and around the Addis Ababa city at altitude around 2400 m.a.s.l. and the average maximum ambient temperature is 280c and the average minimum temperature is 70C. |
|||||||||
| 2 | Pump Casing | The pump design shall ensure that alignment is maintained between the various assemblies by recesses, spigots and dowels and shall be that all components liable to wear can be replaced. Components shall be permanently marked with the manufacturer’s number and where dowels are not used, permanently marked for correct assembly. The pump casing shall have replaceable wear rings. The casing of the pump shall be of a suitable grade of close grained cast iron to BS EN 1561:1997(specification for flake graphite cast iron) grade 220 or ductile cast iron or nickel iron or stainless steel and have flanged or traded connection to match the specified pipe work | |||||||||
| 3 | Impellers | The impellers and guide vane shall be of suitable material preferably cast in high-grade zinc free bronze or stainless steel, accurately machined and smoothly finished to minimize hydraulic losses. The pump shall be equipped with wear rings of renewable/replaceable type, made of zinc free bronze, stainless steel, metal reinforced rubber and having larger bearing surface. The rotating element shall be statically and dynamically balanced before final assembly | |||||||||
| 4 | Pump Shaft | The pump shaft shall be of high tensile strength stainless steel or chrome steel adequately sized, with good fatigue, shock load and corrosion resistant. The duty speed range shall be well below the first critical speed of the shaft. Where a change in diameter of the shaft occurs the shoulder shall have a radius or undercut to appropriate BS to reduce stress concentration. The shaft shall be complete with easily renewable/replaceable stainless steel or bronze protecting sleeves at glands and bearings. | |||||||||
| 5 | Bearings | Bearings shall be rated to ensure cool running and meet the load factors specified. The bearings shall be water lubricated. The motor thrust bearings should be capable to carry thrust load corresponding to the maximum head operating with rotation in either direction. Bearing shall be positively retained within the pump body to prevent the possibility of the bearing rotating; a press fit alone shall not be acceptable. The pump shall be fitted with a suction case of a material suitable for the liquid being pumped and shall be provided with long bearings to stabilize the shaft and motor shaft and to avoid radial thrust on the motor bearing. A screen shall be incorporated having a minimum open area of four times the eye of the impeller. |
|||||||||
| 6 | Submersible Electric Motor | The motor shall be suitable for three phase 380V, 50 Hz power supply and shall comply in all aspects with the relevant parts of BS 4999(general requirements for rotating electrical machines) and BS 5000 (Rotating electrical machines of particular types or for particular types) or equivalent, and shall be designed to run at high power factor and efficiency at the prescribed plant duty. The starting (locked rotor) current of the motor shall not exceed 6 times the full load operating current. Motor starting torque shall be at least 120% of the pump torque requirements throughout the starting sequence. Motors shall be capable of running backwards at rated speeds under backflow conditions without damage to the motor. The motor shall be capable of continuous operation under water. The protection index for motors shall be IP 68. The motor shall be installed vertically and rigidly coupled to the multistage submersible pump such that both the pump and motor are completely flooded and stator should be rewindable. |

1. The PH value is round 5, so we suggest anti- corrosive mateiral SS304;
2. The submersible power cable we need use is 3*70mm and 3*95mm, so 3*35mm and 3*50mm in your enquiry can’t able to work, so
please kindly confirm and then we can quote the cable price for you;
3. The control panel we quote is with soft -start type with China brand, if special requirements, please feel free to contact us for update;
4. For the vulcanizing kits , would you please kindly explain more?
