Neptune DK-13 Plus - Double Motor Battery Sprayer

The Neptune DK-13 Plus is a high-performance double-motor battery sprayer built for efficient and consistent coverage across farms, gardens, nurseries, and greenhouses. This Neptune DK-13 Plus runs on a 12V 12Ah lead-acid battery paired with dual high-pressure diaphragm pumps, delivering a flow rate of up to 7 LPM at 220 PSI. The Neptune spray pump double motor design eliminates manual effort — simply switch on, strap up, and spray. With a 20-litre PVC tank, 60 cm stainless steel spray gun, ergonomic padded backpack frame, and 4 interchangeable nozzles, the Neptune double motor sprayer handles pesticides, herbicides, fertilizer, and liquid nutrients for up to 20 feet of spray height.

Key Features and Benefits:

• Dual Motors: The Neptune DK-13 Plus double motor battery sprayer operates at 220 PSI, delivering up to 7 LPM for faster, uniform spray distribution across large field areas with zero manual pumping effort.

• Long Battery: This Neptune DK-13 Plus battery holds a charge for 4 to 5 hours of continuous use, covering 20 to 25 full tanks per single charge with a fast 3–4 hour recharge time.

• Large Tank: The sturdy 20-litre PVC tank on this Neptune spray pump double motor reduces refill trips, letting the operator cover more ground without stopping mid-row.

• Multiple Nozzles: The Neptune DK-13 Plus includes flat fan, mist, cone, and adjustable nozzles for switching spray patterns to match different crops and field conditions.

• Steel Lance: The 60 cm stainless steel gun and telescopic lance on this Neptune double motor sprayer allow precise targeting of tall crops and dense foliage, reaching up to 20 feet vertically.

• Ergonomic Build: The padded back-support frame and shoulder straps on the Neptune DK-13 distribute weight evenly, reducing operator fatigue during long spraying sessions.

• Dual Mode: This double-motor battery sprayer allows users to run one motor for light misting or engage both for maximum pressure and flow, conserving battery when full power is not needed.

How to Assemble:

• Unbox the Neptune DK-13 Plus and lay out all components — tank, battery, pump unit, delivery pipe, telescopic lance, spray gun, nozzles, straps, charger, and suction filter — cross-checking against the included manual.

• Attach the pump and battery unit to the base of the tank, securing all connection points firmly until each locks into place without play or wobble.

• Connect the delivery pipe from the pump outlet to the telescopic lance inlet, ensuring the rubber gasket is seated correctly inside the joint to prevent leaks under pressure.

• Attach the 60 cm stainless steel spray gun to the lance end, then screw in the appropriate nozzle type for the intended spray pattern before each session.

• Fix the suction filter inside the tank at the bottom inlet port to prevent debris from entering the pump during operation and causing blockages.

• Thread the shoulder straps through the back-frame brackets and adjust them to a comfortable length to suit the user's height and build for long sessions.

• Fully charge the battery for 3–4 hours before first use and confirm the indicator signals a complete charge before filling the tank.

• Fill the tank with the required liquid up to the 20-litre mark, close the lid tightly, and do a short test spray to confirm all joints are leak-free before heading to the field.

Safety Instructions:

• Always wear gloves, safety goggles, and a face mask before operating this Neptune double motor sprayer, especially when working with pesticides or herbicides.

• Never charge the battery near open flames, standing water, or direct sunlight, and avoid leaving it on charge unattended for extended periods.

• Do not run both motors continuously at maximum load for prolonged periods — this can overheat the pump diaphragm and reduce the working life of the Neptune spray pump double motor.

• Ensure all pipe joints, the spray gun connection, and the tank lid are tightly secured before switching the motor on to prevent chemical blowback at the operator.

• After every use, flush the tank and spray line with clean water and run the pump briefly to clear chemical residue from the internal components of the Neptune DK-13.

• Store Neptune DK-13 Plus and the sprayer in a cool, dry, shaded location and partially discharge the battery before long storage periods to preserve lead-acid battery cycle life.

Frequently Asked Questions (FAQs):

Q.1 How long does the battery last on a single charge?

The Neptune DK-13 Plus gives 4–5 hours of spraying time per full charge, covering 20–25 full tanks. Running both motors at once draws more power and shortens backup; using a single motor extends it.

Q.2 What is the difference between single and double motor mode?

Single motor mode runs at lower pressure for light misting or targeted spraying and saves battery. Double motor mode engages both pumps for a maximum 220 PSI and 7 LPM flow — best for tall crops, dense foliage, and large fields.

Q.3 Which chemicals can be used in the Neptune DK-13 Plus sprayer?

This Neptune DK-13 double motor battery sprayer works with water-soluble pesticides, fungicides, herbicides, liquid fertilizer, and disinfectants. Avoid strong acids or solvents that can degrade the PVC tank and diaphragm pump.

Q.4 How do I clean the sprayer after use?

Drain the tank, refill halfway with clean water, run the pump for 1–2 minutes, then remove and rinse the nozzles separately. Wipe the tank dry and store it upright in a shaded spot.

Q.5 Can the battery be replaced when it wears out?

Yes. The standard 12V 12Ah lead-acid battery is widely available at agricultural and battery shops across India. Match the voltage and Ah rating exactly when replacing to maintain safe motor performance in this Neptune spray pump double motor.
