Manual & Electric Knapsack Sprayer 20L for Sale

The Manual & Electric Knapsack Sprayer 20L from Agronest Equipment gives you the best of both worlds in a single, versatile spraying unit. Use the 12V battery-powered electric pump when you want effortless, consistent spraying across large areas, or switch instantly to the manual piston pump if the battery runs low, fails, or if you simply prefer hands-on control. This dual-mode design means you are never left with an unusable sprayer in the middle of a job, regardless of battery status or access to mains power for charging. The 20 litre tank provides professional-grade capacity for extended coverage, and the padded backpack straps keep you comfortable throughout the working day. Multiple nozzle options let you adapt to different spraying tasks on the fly. For professionals who cannot afford downtime and need a sprayer that adapts to any situation, this dual-mode knapsack is the most practical choice in the Agronest Equipment range.

Frequently Asked Questions

Yes. Switching between electric and manual mode is instant. Simply turn off the electric pump switch and begin pumping the manual handle, or vice versa. There is no delay or adjustment needed.

Yes. Both modes deliver a working pressure range of 4–6 bar. The manual piston pump provides the same spray quality and reach as the electric diaphragm pump.

The 12V rechargeable battery provides 4–5 hours of continuous electric pumping, enough to empty the tank multiple times. When the battery is low, switch to manual mode to continue spraying without interruption.

Slightly. The dual-mode mechanism adds approximately 300g compared to the electric-only 20L knapsack, bringing the empty weight to approximately 5.8 kg.

Absolutely. Many users prefer manual mode for certain tasks or choose not to charge the battery for short sessions. The manual pump works independently of the battery system.

You continue spraying using the manual piston pump with no difference in spray quality. This is the core advantage of the dual-mode design — no single point of failure can stop your work.
