Pump,sbmr,dewat/desludging,w/gen.DIESEL

General Description:
Lightweight electrical submersible dewatering or desludging pump for heavily contaminated water with solids up to 50 mm in diameter. Maximum head is 20 m.
A suitable DIESEL generator is included in the kit.

Technical Specifications:

Pump set
2" submersible / immersible pump with cast iron casing, screw type impeller and tandem mechanical seals running in oil bath. Directly driven by 1.5 kW, 400 V, 3 phase, 50 Hz, IP68 motor. The pump is free-standing on its feet. Complete with male hose tail outlet and 25 meters of cable with 16 A plug fed from the generator set. The lead will be looped and cleated around the pump handle to prevent pulling on the internal connections.
A removable anti-dive plate will be attached to the pump to prevent 'boring' in muddy conditions.

Generator
6000 Watt 400 Volt 3 phase 50 cycles brushless generator fitted with hours counter, 1 x 16 Amp output socket protected by a power circuit breaker (ground fault detector) earth leakage trip to prevent fatal electric shocks should the power lead or pump develop a fault or be damaged. The generator shall be flanged coupled to the driving diesel engine.

Engine
OHV diesel engine governed to run at 3000 rpm complete with recoil start, 3 hour fuel tank, low oil protection exhaust system, air and oil filters.

The generator and the engine shall be mounted on anti-vibration mounts inside a robust roll frame.

The Pump and Genset are supplied with following Accessories/Spare parts/Consumables:

Accessories
40 m Pump supporting rope (16 mm)
20 m Electrical extension cable with socket connectors
20 m Cable protection hose (fitted)
25 m 2" lay-flat canvas delivery hose & 2" hose clip
1 x sliding collar to fit over the lay-flat where it exits the well
1 x 2" BSPT male coupling
1 x Two-wheel site trolley for generator set
1 x Tool kit comprising spark plug spanner, screw driver and oil drain spanner
5 x 1.4 litre containers of engine oil (allowing four complete refills plus spillage)
1 x Operators Manual (in English and a second appropriate language)

Spares
One set of spares for 1000 hours operation comprising:
2 x Spark plugs
2 x Air filter elements
1 x 16 A plug
1 x 2" hose clip

Transport and storage:
Packaging: All the items shall be packed in a sturdy plywood case suitable for sea freight clearly marked with "S5006017_Electrical Dewatering Pump with Genset, DIESEL", the gross weight and dimensions. Marks shall be on the front and back of the case, as determined by the runners of the forklift.

Instruction for use:
Use in:
Dewatering
Desludging
Combating localised flooding
Cleaning wells
The maximum head of the pump is 20 m; this package is designed to dewater wells at around a depth of 15 m. If higher heads are required, then two pumps of this type can be coupled together to give a maximum head of 40 m (7 m3/ hr at 35 m head) (see below instructions).
This pump does not pump air; it does not need to be submersed to pump as in the second pump when pumping in series, but when switching on there should always be water in the pump chamber or the seals will burn in 1 - 2 minutes.
The purpose of the base plate is to prevent the legs of the pump sinking in to the mud causing the impeller to try and drill itself downwards, which results in the pump becoming clogged up. If the base plate is not present either suspend the pump just above the muddy bottom, turn it on its side or put it in a large perforated bucket.
If the pump is near its maximum pumping depth the canvas lay-flat may need to be attached to a stake at the top of the well to prevent sliding back into the well. A hose connector can be attached to the end of the lay-flat to make it easier to tie to a stake.
This pump can be used for desludging latrine pits.

Instructions for coupling two pumps together in series:
Using the rope provided, the lower pump shall be suspended (by a loop around the handle) at the bottom of the well. The second pump should be suspended some 15 m above the first pump. If two pumps are being used suspend each pump with a separate rope. Great care should be taken when lowering the pumps and gloves should be worn.
Remove the base plate of the second pump and connect the lay-flat distribution hose from the first pump into the bottom of the second pump, the kit contains a male connector for this purpose.
The electrical extension lead should be attached to the cable form the first pump. The connector is splash proof but not water proof, so avoid submerging this connection under water.

Regularly maintain the engine according to the manual (On the SD Intranet a sample template is posted to assist with the maintenance of the engine). See the generator maintenance sheet via the following link:

Precondition for utilisation:
Trained staff required for operation and maintenance
Choice of petrol or diesel generator determined by availability on-ground and ease of supply.

Alternative if the item is not available:
This is similar to Oxfam kit (code WSDP/6)

Emergency scenarios:
Primary use in removal of unwanted stagnant water or extracting water from shallow wells

Context in which item is mainly used:
Used for resolution of localised (stationary) flooding and dewatering of hand-dug wells

Target population:
Determined by context and application

Emergency scenarios where the item should not be used:
Not to be used in fast flowing water where anchoring in preferred vertical position is difficult

Other Emergency scenario considerations:
In general high volume low lift application
Not designed for continuous use
