From 1 to 20 KM distance with Thumba 1 to 10 Hp Special designed pump sets
Due to water scarcity in almost all areas pumping of water from available area to required long distance areas within 20 kilo meter range by using available minimum power 1 to 10 hp single electric power sources.
Most of agriculture power connection, allotted loads by government are 3hp ,5 hp 7.5 hp and 10 hp only. By using this minimum power source we must design special high pressure motors to pump long distances.
We have specially designed high pressure submersible motors in all power ranges from 1 hp to 70 hp to suite for particular pipe lines based on head and discharge requirements.
Main factors to be considered:-
We must considered following main factors before erection of long distance pipe lines.
- 1. Power availability in hp (EB, Solar, Engine)
- 2. Area to be irrigated.
- 3. Total head from source to end.
- 4. How many litre per day required.
- 5. Diameter of pipe line for future expansion
- 6. Economic status to select quality.
What we Do?
First of all we must survey your complete pipeline areas and distance with total head and discharge needs. To measure total head from starting point to end point we have Digital Altitude meter for exact measurement. After completion of complete field study we give rough quotation for that project.
To reduce labour cost Civil trench making, plumbing, closing of trench Missionary civil works for valve erected areas must be done by customer. We give proper design and co ordinate all work schedules with our person to do successfully.
Materials used in this system:-
Special Designed Motors :-
We have designed in our own brand Thumba single phase 1 hp to three phase 70 hp high pressure pump to meat pressure requirements for particular pipe line. Our popular model high pressure pumps works in various sectors like Rain gun sprinkler systems and long distance Pipe lines in India and foreign countries.
Thumba GSM Auto Starters:-
We also designed manual and automatic control device for motor ON and OFF based on time based on our programmed time. Also we offer with mobile phone controlled starters with 12 type of safety features like single phasing ,over volt, low voltage, dry run, etc.,
Original ISI grade PVC pipes with 4 kg/cm2 and 6 kg/cm2 pressure rating is essential. Never use second quality re extrude pipes for long distance pipe lines. In some cases GI and HDPE pipes required to cross rivers, channels and rocky areas.
During water flow in pipelines air bubbles travel through the water on top side of pipes. This will generate friction and reduce the flow up to 10% of discharge. Also leads to pipe burst because of water hammering during motor stop, So we must provide highest quality 2 inch Air valves in particular intervals based on field conditions.
Non Return Valves ( NRV) :-
To avoid return water hammering Non Return Valves are very much important. Many factors to be considered when locating Non return valve to get full performance. Otherwise it will not function properly. Various NRV models available in markets. But based on my experience up to 100 mm diameter Ball type non return valves are better. Wafer type valves also used for above 250 mm diameter pipe lines.
Pressure Releaser Valve:-
During excessive pressure build up inside the pipe lines so many chances to damage pipes and fittings due water hammering phenomena. To avoid pipe damages we must release excessive pressure inside the pipes. For that good quality durable pressure releaser valve is very much important. We offer 2 inch diameter stainless steel spring fixed aluminium body pressure release valve to our customers. You can fix pressure ratings from 1 to 10 kg/cm2 based on operating pressure of particular pipe lines.
