How to Choose the Right Domestic Pump
Head, flow, suction lift and power supply — the four numbers that decide which pump belongs in your home.
Start with Head and Flow
Measure the vertical distance from your water source to the overhead tank and add pipe friction losses — that is your head. Flow decides how fast the tank fills; a typical 1000-litre tank wants a pump rated around 1.8–2.0 m³/h.
Self-Priming or Not?
If the pump sits above the water level — an underground tank or shallow well — a self-priming monoblock like the Kirloskar JALRAAJ saves you from re-priming after every power cut. Flooded-suction installations can use simpler, cheaper designs.
Match the Power Supply
Rajasthan's rural feeders see wide voltage swings. Choose a pump with a wide voltage band and thermal overload protection, and never undersize the cable run to the pump.
Buy for Lifetime Cost, Not Price
A cheap pump that burns out in two summers costs more than a branded one that runs for ten. Genuine KSB and Kirloskar models carry real warranties and spares you can actually get.
