Balaji Industrial & Agricultural Castings

Excessive fluoride in drinking water is harmful and causes dental and skeletal flurosis.

Aluminium sulphate on addition to water, hydrolysis to form white aluminium hydroxide flocs which during flocculation, trap only fluoride ions.  The flocs have to settle under quiescent conditions.

Floating flocs are removed by filtration. Filtered water is fit for consumption after disinfection.

A Transformer is a static Electrical device which essentially transforms voltage or current, the total power remaining unchanged, except for a small loss in the process.

A good transformer in essence is one with low losses, with least percentage regulation and low-maintenance of electrical machine.

A good heat transfer design gives a maintenance-free, long-life transformer.

Use of Low-Viscosity high insulation oil of special grade gives longevity to the transformer.

Use of space-saving, high-efficient cooling fins is the most important tip for long life.

The core - the heart of the transformer - if selected and finished well, the losses are minimized.  It is wise to spend initially more and have a good core to minimize the recurring losses.

Raw Material & Components

Core
Superior quality low-loss CRGO stampings are selected and cutting is done on high precision guillotines for no edge-burrs.  Good design added to this will give a very low core losses which is a big saving to the consumer.

Windings
High conductivity electrolytic grade copper wires, insulated by paper are used in the winding of the transformers.

Grit Blasting
After fabrication, the surfaces of tanks are grit blasted at our Factory premises before painting.  Grit blasting improves the life of M.S. parts as it removes the rust completely and also gives better finish.

Radiators
Special high conductivity alloy steel ultra-thin, resistance welded or friction pressed, radiator fins and assemblies are used. These are pre tested and assembled with body of the tank.

Fittings
High quality fittings as prescribed by international and IEC standards are selected for mounting on to the transformer.

Assembly

• Precision machined and high skilled Engineering assemblies for tap changing mechanism are used for giving trouble-free and reliable operation.
  
  
• Good quality brass diagram and name plates are used for fixing on the transformer body.
  
  
• Precision quality High tensile steel fasteners are used in Assembly.
  
  
• Special washers and locknuts used to give rattle-free operation and dynamic stress with standability.
  
  
• Good seasoned wood blocks are used in the packing and fixing the gaps.
  
  
• Special quality rubberised cork or synthetic cork sheets are used for gaskets and packing.
  

Effect of Excess Iron in Drinking Water

Water becomes brackish color, rusty sediment, bitter or metallic taste, brown-green stains Water gets iron bacteria, discolored beverages Excess iron causes gastrointestinal distress Certain types of bacteria thrive in water with iron content and give it a rotten egg smell.

Efficiency & Performance

Iron Content In Water	Volume of Water that can be treated	Period for Regeneration
Up to 5 mg/lts.	2,40,000 lts.	45 days
5 - 10 mg/lts.	1,26,000 lts.	30 days
10 - 50 mg/lts.	1,18,000 lts.	15 days

BALAJI Solar Submersible Pump's motors are designed to operate directly on Solar modules. The system does not contain a Controller and it works uninterruptedly when sufficient sunshine is available. The motor will drive standard multi-stage centrifugal 'pump-ends'. The 'pump-ends' are constructed from marine grade bronze and 304 stainless steel. The impellers and diffusers are constructed from a rugged thermoplastic material and are extremely resistant to mineral and algae deposits. On-site servicing of the 'pump-end' is easily accomplished without the use of specialized tools.

BALAJI Solar Submersible pumps are designed for use in stand-alone water delivery systems. They are pollution - free, corrosion-resistant, self-lubricating and noise-free. Probably there is no better way to provide water for remote homes, campsites, live stocks, small farms as well a many other needs beyond the commercial power grid.

Advantages:

• Simplicity: Operates directly on Solar modules or Batteries without a controller or any other electronics.
• User friendly: Does not require any skilled manpower to install a system. Since 'Reverse polarity protection' is incorporated, the system will work but the discharge will be less. Hence it is important to connect the terminals correctly to derive the desired discharge.
• Maintenance free: The brushes used have a life of 20,000 hours of operation, which equals 3000 days of operation at 6 hours per day of usage.
• Overload protection: The built in magnetic drive protects the motor from overload or pump obstruction.
• Flexible to various applications: Wide range of capacities is available. The selection can be made with most efficient 'pump-end' for given head simply by choosing the pump with the best number of stages for desired applications.

The below mentioned data shows typical capacities of BALAJI Submersible solar pumps at various rated voltage operations. The volumes mentioned in the data are based on a Solar radiation of 5.5 kWH/m2/day with suitable tilt angle of the Solar array.

Benefits of using Surface Pumps:

• Rugged construction of the pump keeping in mind the various conditions and handling.
• The wear and tear of the brushes is very low and brushes last for 2 years under normal operations of 8 hours per day.
• Cast iron/bronze impellers are used in the pumps have high corrosion resistance and can be used even if the sedimentation content id high. Rusting or corrosion has negligible impact on life/performance of the pump.
• Impellers in all the pumps are positively fixed to shaft by a solid key arrangement. This prevents the impeller to loosen and the pump can also be rotated in both the directions without any harm.
• Pump spares are easily available and are inexpensive.
• We also develop the pumps as per the Customer requirements and site conditions.
• Warranty: Solar modules are warranted for a period of 10 years against faulty performance and there's a comprehensive warranty of one year on the Pump.
