5 YEARS WARRANTY. Specification 230V/50Hz, 25 mm delivery,3000LPH @ 30m Height SPECIFICATION: Ensure motor must be filled with clear water before connecting to supply If you are using this pump with more than 100 feet cable length, there is a possibility of voltage drop. Please select appropriate cable Pump should not run dry run, Please ensure to run the open well submersible pump with adequate water above it Installation Instruction: No rigid foundation as such is essential for installation under water. It can be installed either by hanging with a suitable rope to the eyehooks or keeping at the bottom of the well where the muddy area is less. While lowering the pump, it is essential that the pump is lowered without damaging the cable or outside parts of the pump. Ensure that cable or any part of the pump does not come in contact with the walls, pump or pipeline. Do not use cable as a rope for lowering the pump, Cable shall be tied with a delivery pipe using a suitable thread/ wire at every 1.5 mt. distance. After lowering the pump check continuity between phase, also check insulation resistance between winding and between cable and earthing. It is advised to run the bore well submersible pump every day for a few minutes. This helps in removing the particles deposited on the rotation parts. If the open well submersible pump is not used for a few months, there are chances of getting it jam APPLICATION : Domestic use in Apartments, Buildings and Hotels Small farms and Gardening Irrigation Water supply for fountains Overhead tanks and sumps. FEATURES Designed for under submerged condition water applications. *All rotating parts are dynamically balanced for longer bearing life and Vibration free smooth operation Epoxy ceramic coated in the inner parts for rust free operation Fitted with Quality Oil seal Easy for installation and no platform required Designed to withstand wide voltage fluctuations Non overloading power characteristics no fear of motor burning.
Topping up the motor Unscrew the Brass Plugs 1 and 2, fitted on top of the motor as shown in Fig. 1 below, and fill the motor with pure drinking water till water overflows from the other filling hole. Gently rock the motor to release air bubbles and further top up if necessary. Then replace the two plugs.
The brass Plug 3 mounted on the bottom of the motor, is used for draining the water from within the motor. Ensure all three Brass Plugs are tightened to prevent leakage of water from within the motor. Check for leakages before lowering the OWS. Use prescribed pipe sizes as mentioned on the product name plate. Check the level of silt at the bottom of the well. Refer Fig. 2, shown below, for locating the OWS for operation with flooded suction
Use the eye bolts / lifting lugs for lifting / lowering the OWS using appropriate equipment. Keep the wire ropes remains tied for lifting of the pump set for future. To prevent the motor from getting exposed during pumping, ensure the suction strainer is fitted above the level of the motor. This is done by fitting one end of a bend to the pump suction flange and the strainer to the other end of the bend, thereby ensuring that the level does not fall below the strainer.
Water proofing the submersible motor cable – supply cable joint DOL OWS Motors are supplied with a single 3 core PVC insulated flat cable of length 3 meters. The free end of the 3 core cable of the motor needs to be connected to the supply cable from the control panel. As this joint is always nearly submerged in water, the joint needs to be water proof.
SD OWS Motors are provided with two separate 3 core PVC insulated flat cable, each of 3 meters length. Repeat the procedure for both 3 core PVC flat cables from the motor to the two cables from the Control Panel.
Electrical installation As far as possible, do not use multiple joints in the electrical cabling while connecting the Control Panel to the OWS. Ground the pump set using the two earth screws provided on the leg of the motor body. Ensure electrical joints, if any, are properly and adequately insulated. Connect the cable properly to the starter terminals to avoid loose connections. Factor in low voltage operation while selecting cable size.
Checking rotation of OWS Power up the OWS and observe the discharge from the pump. Next interchange any two phase wires, power up the OWS and observe the discharge from the pump. In case the discharge is more after interchanging any two phase wires, then the impeller is rotating in the correct direction within the volute casing. If the discharge after interchanging any two phase wires is lower, then the previous phase wire connection was correct. Now revert back to the old phase wire connection.
