Battery Spray Pump 12x8 vs 12x12 vs 12x18 Double Motor: Which One to Buy?

By Pragati Agrotech Technical Team, Nashik · Updated 8 October 2026 · 2 min read

Quick answer

In battery spray pumps, the first number is the 12-volt system and the second number refers to the battery size. A 12x8 pump has a lighter 2 kg battery and suits small farms and gardens. A 12x12 pump has a stronger 3 kg battery for longer daily spraying. A 12x18 double motor pump uses two motors, a 3 kg or 3.4 kg battery and a 20-litre tank for heavy-duty spraying on large farms.

Which pump suits which farmer?

12x8: you spray a small area, want the lightest pump, or need a pump for a garden or nursery.
12x12: you spray most days and need the battery to last longer without recharging.
12x18 Double Motor: you spray large fields, orchards or tall crops, or you do spraying work for other farmers.

Battery care tips for longer life

Charge the battery fully after every use, and do not leave it fully discharged for long.
Use the charger made for your battery (for example a 12V charger with overcharge protection).
Rinse the tank and nozzle with clean water after spraying chemicals.
Store the pump in a cool, dry place away from direct sunlight.

Spare parts

Motors, chargers, nozzles, spray guns, straps and switches are the parts that wear out most often. Pragati Agrotech supplies pump motors (3.6 to 7.5 LPM), chargers and sprayer accessories, so dealers can service pumps quickly.
