Submersible pumpsets sell to farmers through dealers, to state solar-pump tenders and to water-supply contractors, and that mix of buyers shapes how a plant is planned. A submersible pump manufacturing consultant helps you choose the product range, motor technology and capacity before you commit to machinery. NPCS, working since 1994, prepares project reports and supports entrepreneurs through technology, vendor and approval decisions for pumpset units.

Investment basis: excludes land.
Figures are indicative ranges. Your project report works them out for your capacity and location.
Market Demand for Submersible Pumps in India
Demand for submersible pumps rises as groundwater falls and farmers drill deeper borewells. Irrigation, rural water supply and solar pump programmes are the main drivers. Manufacturing is concentrated in Coimbatore (Tamil Nadu), Rajkot and Ahmedabad (Gujarat), Kolhapur and Bengaluru, so new units compete with established clusters. Sales peak before summer and sowing, then dip in the monsoon. Exports are of medium potential, mainly to Africa, the Middle East and South-East Asia.
- Farmers buying through dealers
- Government solar-pump tenders
- Water-supply contractors
- Builders needing construction dewatering
Submersible Pump Products You Can Make
Most new units start with borewell submersibles and add other types later. Solar pumps with controllers suit tender-focused businesses, while sewage and dewatering pumps serve contractors and builders. Openwell pumps are a simpler addition for existing dealer networks.
- Borewell submersibles (V3/V4/V6/V8)
- Openwell submersibles
- Solar submersible pumps with controllers
- Sewage and dewatering pumps
Submersible Pump Manufacturing Process
The submersible pump manufacturing process builds the motor and the pump stages separately, then joins them in assembly. The motor side covers stator stamping, winding and rotor die-casting. The pump side covers machined shafts and casings and stacked impellers and diffusers.
Quality is controlled at the end of the line. Each pump is tested for head-discharge performance, efficiency, insulation resistance and a high-voltage test under IS 8034. Technology choices include wet-type or oil-filled motors, BLDC/PMSM motors for solar pumps and CNC machining.
- Stator stamping and stacking
- Winding
- Rotor die-casting
- Machining of shafts and casings
- Impeller/diffuser stacking
- Motor and pump assembly
- Performance, insulation and leakage tests
- Painting
- Packing
Raw Materials and Machinery for Pump Manufacturing
Your main inputs are electrical steel stampings, copper winding wire, CI/SS castings, stainless shafts and pipes, bearings, cables and capacitors. Castings usually come from foundries in Coimbatore and Rajkot. Winding machines, rotor die-casting and CNC machining centres decide motor quality, while a borewell test tank proves performance before dispatch.
- Winding machines
- Rotor die-casting
- CNC lathes and machining centres
- Balancing machine
- Assembly lines
- Borewell test tank
- Paint booth
Licences and Approvals for Submersible Pump Manufacturing
Approvals start with unit registration and a factory licence, followed by State Pollution Control Board consent. Dry assembly is White category, while painting and rotor die-casting generally place the unit in Green. Product approvals come next: IS 8034 certification and BEE star labelling. Solar pump supply also needs MNRE or state empanelment.
| Pollution category | Dry engineering assembly: White (CPCB S.No. 51); with painting: Green (125); rotor die-casting: Green (106) |
|---|---|
| HSN code | 8413 70 (centrifugal pumps incl. submersibles); 8501 (motors) |
| GST | Pumps fall under HSN 8413: hand pumps moved to 5% under GST 2.0, while power-driven submersible pumpsets follow their own entry; NPCS applies the current rate in the project financials |
| BIS / quality control order | Submersible pumpsets are made to IS 8034; government and solar-pump tenders require BIS certification and BEE labels |
| Other licences | BEE star-labelling registration; MNRE/state empanelment for solar pumps; factory licence |
Quality Standards and Certification for Pumpsets
Certification decides which buyers you can reach. Government and solar-pump tenders require BIS certification to IS 8034 and BEE labels, so dealer-only sales are not enough to grow. Solar pumps must also meet MNRE specifications. Plan test equipment and documentation early, because performance, insulation resistance and HV test records support every certificate application.
Managing Seasonality and Working Capital
Pump sales peak before summer and sowing and dip in the monsoon, so cash needs move through the year. You will build stock of motors and castings ahead of the peak, while dealer payments arrive later. Copper is a large cost item, so buying plans and credit limits matter. Your project report should size working capital for this cycle.
Government Schemes and Project Finance
Relevant programmes include PM-KUSUM for solar pump vendor empanelment, Jal Jeevan Mission for water supply demand and state subsidies on farm pumps. Some of these support buyers rather than the plant itself. NPCS reports are used for bank loans and government programmes such as PMEGP, MSME schemes, Mudra and NABARD-linked projects, subject to each lender's requirements.
What Decides Success in a Submersible Pump Unit
Good operators focus on efficiency, reliability and after-sales service. The main risks are listed below.
Machining scrap is the only by-product, and it can be sold.
- Copper price swings affecting margins
- Price competition from established clusters
- Warranty claims from field failures
- Dealer and service network gaps

Submersible Pump Manufacturing: Frequently Asked Questions
How much does submersible pump manufacturing setup cost in India?
An indicative investment is ~₹1–25 crore, excluding land, depending on capacity. Plants range from about 5,000 to 2 lakh pumps a year. Your project report works out the exact cost for your machinery, product mix and location.
Which licences are needed for submersible pump manufacturing?
You need a factory licence, State Pollution Control Board consent, IS 8034 certification and BEE star-labelling registration. Dry assembly is White category, while painting or rotor die-casting makes it Green. Solar pump supply also needs MNRE or state empanelment.
How much land and power does a pump plant need?
Land typically ranges from about 0.5 to 5 acres, and connected power from about 100 kW to 1 MW. Water need is low because test water is recirculated. Exact figures depend on your capacity and machinery.
How to start submersible pump manufacturing?
Begin by fixing your product range, such as borewell or solar pumps, and your target buyers. Then finalise capacity, technology and location, and prepare a project report. Approvals and machinery orders follow. NPCS can guide each step.
