Indicative Price : 12,603.15 USD

General Description:
Electrical submersible pump, for boreholes, with a capacity of 18 m3/hr at 80 m Total Manometric Head.

Technical Specifications:
Complete Electrical submersible borehole pump, for pumping non-aggressive water without solid particles, all materials approved for use with drinking water. The pump is provided with a priming screw, top non-return valve, bottom inlet strainer and water lubricated bearings.
The standard pump is directly coupled and equipped with a 3-phase submersible motor, suitable for power supply of 380 V/400 V - 50 Hz - 3-phase. The motor is expected to be of maximum 7.5 kW. The embedded stator winding in the submersible motor is hermetically enclosed in stainless steel. Enclosure class IP 58. Built-in protection device dry running, including level relay electrodes. Complete with motor cable.

Pump and motor are supplied with body and shaft, impeller/diffuser assemblies all parts in AISI 304 (DIN 14301) stainless steel, water lubricated bearings in Noril glass fiber impregnated thermoplastic resin/stainless steel, and complete with electric cabling.

Pump size: The pump must be able to fit and work correctly in borehole casing of not more than 6 inches (150mm inside diameter).

Supplied with:
1 x 100m meters of electrical (drop) cable, submersible, water tight to at least 3 bars and approved for use with drinking water
1 x kit, cable termination for cable jointing to pump, two component type (not shrinkable).
Sufficient sets of cable clips (one every 3 m).
1 x set of electrodes.
1 x electrode cable, 1x1.5mm2, installation length according to drop cable length.
1 x starter, reduced start current by auto-transformer or soft, 3x380-415V kit in control panel. W/ammeter, voltmeter and electrode relay, time delay relay and earth leakage system
1 x protection device, dry running, including level relay electrode sets.
1 x well head, galvanized, with base plate and complete with cable gland for power and electrode cables, threaded hole with plug for dip meter, pressure gauge, gate valve and elbow 90°.
Set of stainless steel couplings for 2" flexible riser hose, i.e. for connection of hose to the pump, and for connection of hose to the well head.
1 x Standard tool kit.
1 x spare parts kit/Service kit, sufficient for 2 years of operation.
Instruction, operations and maintenance manual
1 x set of flexible RISER PIPES - TO BE SUPPLIED as roll of lay flat Flexible Hose for use with borehole pumps. Supplied in standard coil length of minimum 75 meters, with the appropriate diameter for the actual pump outlet and capacity - Hose set or meter unit price to be quoted clearly.

All parts in contact with the water must be of materials approved for contact with drinking water. Certificates must be available.

Specifications like UNICEF Catalogue number S5006057, and following: The heavy duty Flexible Hose is made of reinforced polyester and thermoplastic elastomer composite (like e.g. Wellmaster, Foraduc, Flexwell etc.), complete with above indicated two separate threaded stainless steel couplings (ISO-Fix or equivalent type) for connection to the submersible pump outlet and to the well head. If already mounted, at least one of the couplings must allow an easy and secure adaption of the hose length to the actual installation conditions. The flexible hose will also be supplied with a Hose-Roller for installation / pulling out of borehole pump.

The submersible pump or the flexible riser pipe will be supplied prepared for potentially draining the water out of the riser pipe for making the pull out of the borehole pump feasible by human power. This disposition should preferably not empty the riser pipe at each stop of the pumping, to avoid regular twisting of pipe.

Transport and storage:
Packaging: Each pump set is packed individually and complete with its corresponding accessories, cable lengths etc.

All the above packed in one timber crate suitable for sea/air freight, lined with Kraft Union paper. Base timbers have minimum of 4" fork lift runners suitable for offloading by jack/poles etc. Case is to be finished with a minimum of 2 steel bands.

Pump serial number and purchase order number to be clearly marked on case.
Crate outer to be marked "S5006054 Electric pump boreholes" with overall dimensions in CMS and gross weight in KG clearly shown. Marks to be both on the front and back determined by the fork lift runners.

Weight/Volume/Dimensions:
Estimated weight: 110 kg
Estimated volume: 0.55 m3

Instruction for use:
The unit is used for pumping non-aggressive water without solid particles from boreholes, or similar water sources (stationary or slow moving water only)
In situations where there is no electric power supply or frequent power cuts are experienced, it is recommended to order a generating set to match the specification of the pump.

The generating set must be of sufficient capacity to provide the start current required for above, i.e. with Auto-Transformer starter a generating set of at least 15 to 20 kVA (internally regulated type, altitude max 1000 meters, 100% humidity and max 40 degr.C ambient). For the above pump, the starting is supposed to be Auto-Transformer.
D.O.L.(Direct-On-Line) can be used, but will require about 25% higher start current from the power source.

Country Offices must clearly specify if a different voltage and phase rating of pump motor is required; as well as, different length and rating of electrical cable (length should be enough to meet the submerged pump well depth and any surface cabling requirements), connectors, fittings, switch gear and generator if needed etc.

While ordering pump kit it should be noted that this size of pump might have the possibility of applying 4" and slim 6" diameter motors. Both will normally suit a 6" borehole casing. Should the borehole diameter be inferior to 6", then Field Office must specify the actual maximum diameter of the borehole.

Precondition for utilisation:
Trained and or experienced staff for installation
Trained staff for operation
Required access to reliable and appropriate power supply
Requires suitable location for mounting of control panel and switching gear with restricted access
