Modern single-phase submersible pumps have replaced older jet pumps and air-compressor systems for one clear reason: they deliver more water, run quieter, and cost a fraction per month to operate. Thumba's residential pump range has been designed specifically for Tamil Nadu bore wells — handling the voltage fluctuations, depth variations and hard-water conditions common across the state.
Single phase pumpsets are no longer just "1 HP for the house bore well". Here are the newest developments in the sector. Most of them were designed and introduced by our own team.
Higher performance single phase motors with stainless steel fabricated impellers are already on the market, with unbeatable performance and a very long motor life of 15+ years. Why fabricated impellers perform better →
Complete SS pumpsets with 100% stainless steel parts, introduced for coastal sea water use. All bolts and nuts, the thrust pad body and the collets are made from pure SS-304 grade parts to withstand sea water salt and chemicals.
Pumping from up to 300 feet has been achieved with a single phase 1 HP pumpset, for deep well operations where single phase is the only power option.
Sewage and mud removal motors with an SS body and 35 mm solid handling, designed and manufactured by us for special purpose applications. Pumps up to 20,000 litres per hour at a maximum head of 12 metres on just 1 HP. See the sewage mud pump →
A single phase high pressure monoblock designed by us for 60 metre head (6 kg/cm² pressure). It handles high pressure cleaning work as well as 200 ft vertical pumping for 10 to 15 floor apartments. A very rare pump that uses our own simple centrifugal pumping concept with only 1.5 HP.
An extreme high discharge single phase submersible pumpset delivering 60,000 litres per hour at 10 metres head within 2 HP power. We introduced it in 2018 for a 10-acre drip irrigation project at Pondicherry, India. The first of its kind.
High pressure pumpsets for advanced irrigation, introduced by us in 1.5 HP and 2 HP to run RainGuns with 65 to 70 feet radius coverage. Suitable for small farmers with up to 2 acres under RainGun. RainGuns for 1.5–5 HP →
For special purpose bore holes, we make 2.5 inch and 3 inch diameter single phase submersible pumpsets for small 3″ and 4″ bore wells. Working depth 50 to 120 feet, power 0.5 HP to 1.5 HP, for low-depth household use. Delivers 40 to 60 LPM.

We have more than 120 models of single phase submersible pumpsets. Every model has its own special character in pumping capacity, material of construction, technology used, head, discharge and cost.
From my 23 years of experience in the pumping sector: do not erect a single phase submersible pumpset in a bore well deeper than 600 feet. We do have a 1,000 ft, 4 HP single phase pumpset model, but voltage problems appear in every area when running 1,000 ft motors, and they need special step-up units.
Just imagine a single phase 220 V supply with 1,000 feet of insulated submersible cable (even when 6 sq.mm cable is used). Transmission losses affect motor performance. If you give 210 V at the starter, only about 160 V finally reaches the motor. How can it pump from 1,000 feet? In this case, select a three phase motor of the same power for that bore well.
Please don't make a mistake here. It will cost you your money and your peace of mind. Consult your nearest pump specialist to select the right pump, or call me on +91 98433 35703 for exact pumpset selection.
Also note: single phase motors above 2 HP do not give good performance or long life.

The exact price depends on your bore well depth (total head), the discharge rating you need and the cable length.

A Thumba 1 HP single-phase submersible pump delivers up to 100 litres per minute — about 6,000 litres per hour — at a 200 ft bore well, filling a 1000-litre tank in 8 to 12 minutes. Discharge reduces gradually as the bore well depth increases.
For most urban homes with a bore well up to 200 ft, a 1 HP single-phase pump (100 LPM) is ideal. For a 400–500 ft bore well choose 1.5 HP, and for very deep 550 ft bores or higher flow (apartments, small farms) choose 2 HP. All Thumba models run on 150–250 V single phase and need only a 4.5-inch bore well.
Our models cover 110 ft to 550 ft. The 1HP model suits up to 200 ft; the 1.5HP covers up to 500 ft; the 2HP reaches up to 550 ft. Share your bore well depth and we'll recommend the right model.
Very little. A 1HP Thumba pump takes about 4 to 6 hours a month to pump 14,400 litres (a 4-member family's monthly need) from a 200 ft bore well, depending on the depth at which water is available. At about 1 unit per hour that is around 6 units a month, or roughly ₹60 per month at ₹10/unit, for your entire family's water.
The 1HP 200ft model fills a 1000L tank in 8–12 minutes. The 2HP 180ft model fills it in just 6–8 minutes.
Our standard 1HP–2HP models need a minimum 4.5-inch bore well casing, and most modern bore wells in Tamil Nadu are 5–6 inch. For small 3-inch and 4-inch bore wells we make special 2.5-inch and 3-inch diameter single phase pumpsets, 0.5 HP to 1.5 HP, for 50 to 120 ft working depth, delivering 40 to 60 LPM.
Yes — all models operate on 150V to 250V single phase. For areas with extreme voltage drops below 140V, we supply a stabilizer that maintains 200V+ input.
Yes. We supply, install and service across Tamil Nadu. Contact us with your bore well details for a site-specific recommendation and installation quote.
We do not recommend it. From 23 years in the pumping sector, our advice is not to erect a single phase submersible pumpset in a bore well deeper than 600 feet. On a 1,000 ft cable, voltage losses mean 210 V at the starter can reach the motor as only about 160 V, which is not enough to pump from that depth. Choose a three phase motor of the same power instead. Single phase motors above 2 HP also do not give good performance or life. Call +91 98433 35703 for exact pumpset selection.
Yes. For small 3-inch and 4-inch bore wells we make special purpose 2.5-inch and 3-inch diameter single phase submersible pumpsets, 0.5 HP to 1.5 HP, for a working depth of 50 to 120 feet. They deliver 40 to 60 litres per minute and suit low-depth household use.
