Major agricultural pump categories
- Submersible borewell pumps: Multistage centrifugal pumps submerged deep within borewells; ideal for high water heads and deep water tables across arid and hard-rock terrains.
- Centrifugal monoblock pumps: Surface-mounted motor and pump sets installed near open wells, farm ponds, or riverbanks; suited for shallow water suction heads up to 7 to 8 meters.
- Solar agricultural pumps: High-efficiency DC or AC submersible/surface pumps powered directly by solar photovoltaic panels, eliminating diesel expenses and erratic grid blackouts.
- Diesel engine pump sets: Portable engine-driven centrifugal pumps for emergency flood irrigation in un-electrified remote fields.
Key technical selection parameters
Calculate Total Dynamic Head (TDH) by adding vertical suction lift, vertical delivery height, and friction pipe losses. Match flow rate (liters per minute or LPM) to your irrigation system: drip irrigation and micro-sprinklers demand regulated pressure heads, while flood irrigation requires high volume discharge at lower pressures.
BEE energy ratings and PM-KUSUM solar subsidies
- Select Bureau of Energy Efficiency (BEE) 5-star rated energy-efficient pumps to reduce monthly agricultural electricity consumption by up to 30%.
- PM-KUSUM Component-B provides up to 60% capital subsidies (central and state contributions) for standalone solar water pumping systems.
- Farmers apply through their respective state renewable energy development agencies (such as MEDA, HAREDA, or UPNEDA).

Common questions
What is the difference between a monoblock pump and a submersible pump?
A monoblock pump is mounted on dry surface land for shallow water sources, while a submersible pump is submerged underwater inside deep borewells.
What government scheme provides subsidies for solar agricultural pumps?
The PM-KUSUM scheme (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan) provides substantial capital subsidies for solar irrigation pumps.
Why are BEE star ratings important for agricultural pump sets?
BEE 5-star pumps consume significantly less electrical energy for the same water discharge, lowering operational bills and motor burnout rates.
