The Silvan Spotpak is a compact portable sprayer.
Whether you are a commercial grower, or a home gardener you will find many uses for this unit. The tank pump and
wand fittings are corrosion resistant and are suitable for applying weedicides, herbicides, insecticides, fungicides,
miticides, organic and green formulations.
It is designed for spot spraying but may be used in conjunction with a boom for boom spraying.
50, 100 or 200 liter molded translucent U.V. stabilized
and impact resistant polyethylene. Screw on lid has
anti-spill breather.
Smoothflo 12 volt DC electric, 7 L/min open
flow, Max 120psi on demand electric
pressure switch. Valves: Viton, Diaphragm:
Santoprene. The Smoothflo pump is designed
with adaptive pressure sensing technology that
prevents pressure spikes while maintaining
higher pressures and flows
On/Off power switch.
The pump is fitted with an automatic electric pressure
sensing switch which automatically starts the pump
when the pressure falls and stops the pump when the
pressure reaches 120 psi

Silvan Spotpak’s feature a positive displacement diaphragm pump with a pressure sensing switch. The pressure switch
interrupts power to the pump when the system pressure builds towards maximum and power is resumed to the motor
when the pressure falls.
When the spray lance trigger is depressed fluid is released and the pressure will drop allowing the pressure switch to
resume power to the pumps motor.
Depending on your spraying requirements you may need to change or adjust the nozzle to suit your desired droplet size or
spray pressure.
Spotpak’s fitted with the Smoothflo model pump are designed not to pulsate and should stop pumping when the valve or
spray gun trigger is released. If the pump fails to stop pumping see the trouble shooting section.
Do not exceed the vehicle manufacturer’s specified safe load and carrying capacity.
The hose is supplied fitted at one end to the spray lance.
Fit the white elbow fitting to the outlet of the pump and finger tighten.
Position the sprayer so as to minimise contamination to the operator. With the pump mounted away from operator the
risk of contamination due to hose failure can be minimised. It is recommended that the sprayer be securely attached to
any ATV or other vehicle. Refer to manufacturer’s instructions for appropriate load limits and fitting positions.
Note : 1 litre of water = 1 kg.
Never fill spray tank to a capacity beyond the specified overall weight limits set by your vehicle manufacturer. Recesses
in the top of the tank allow for tie down straps. When fitted these should be firmly secured to approved attachment
points on the ATV or other vehicle.
The sprayer should be mounted centrally and as near to the centre of gravity of the ATV as possible. It should not
protrude so as to cause an obstruction.
For 50L spotpak sprayer, there is a gasket which
should fit between lance and trigger. The small
side is positioned face to trigger.
Supplied with the Spotpak is a pair of clips for holding the
Spray lance to the tank for easy storage and transport. To fit
orientate the clip as shown and pres to the locating lug in the
tank. Below the Lug is a threaded brass insert embedded in
the tank; attach the provided screw to tank using a phillips
head screwdriver.
The Sprayer requires a 12 volt DC power source. A three metre loom is provided
with the sprayer to allow the sprayer to be connected to the 12 volt DC source
available. Connect the alligator clips remembering the brown or red wire is positive
and the blue or black is negative. The other end of the power loom features a plug
with keyway to ensure connection with correct polarity that connects to the pump. If
you extend the wire use wire of the same gauge or larger.
An on/off switch is fitted to the sprayer to allow the sprayer to be switched off from
the 12 volt DC source to prevent accidental drain of power. The switch also allows
the pump to be shut down when the tank is empty preventing overheating and damage
to the pump.
The wiring loom is installed with a 10 amp blade fuse to prevent any potential
damage to the electrical system of the vehicle.
It is always recommended that you first test all spray equipment thoroughly with clean water.
Silvan Spotpaks are supplied with a blue adjustable nozzle containing a large orifice which when twisting the tip can
allow for a greater flow of liquid. It is recommended that adjustable nozzle is used first and can be changed later if you
Be sure to wear safety equipment as recommended by the chemical manufacturer before adding chemical to the
Check the suction line foot filter is clean and undamaged (see Maintenance section).
Fill the tank with clean water.
With the 12 volt supply connected and the 6 meter spray hose and spray lance connected. Fit the blue adjustable
nozzle or any large orifice nozzle you may wish to use.
Check all pipes, hoses, hose clamps and connections for leaks or damage.
Switch the pump ON.
Depress the spray lance trigger. The pump is self priming and will start spraying within 30 seconds.
Check the hose connections for leaks, if any are found stop the pump and rectify the problem before continuing.
Slowly twist the tip of the nozzle from a course droplet size to a fine droplet to your preference. You can check the
spray pattern by spray pattern by spraying water on to a dry concrete floor.
Dispose of unused chemical and water used for rinsing in a manner that will not endanger people animals or
the environment.
After spraying rinse out the spray lines and tank with clean water
The foot filter should be checked and cleaned if necessary each time the tank is filled. To check the filter hook it out with
a bent piece of wire. Appropriate protective equipment including gloves should be used whenever maintenance is carried
If heavy frosts are experienced, run the pump to make sure pump and spray lines are dry. This will prevent water
freezing in the pump or spray lines and damaging sprayer.
Ensure battery wires are connected to battery properly. Check the inline Fuse in the power loom Check battery is not flat or low Check terminals are fitted to On/Off power switch Check that 2 wires are connected to pump pressure switch Pump does not operate
The pump continues to run when
the spray gun is off
• Check if there is a slow leak of liquid. Check all hose connections and the spray gun for any leaks. • Check the tank is not empty or the suction filter is not fully immersed. • The pressure switch may need adjusting, the pump will need to be removed and generally 1 turn anticlockwise with a 1/16” allen key will correct the problem Pump operates with no flow or
reduced flow
• The pump will only prime if the gun trigger is on. • Check the filter in tank or nozzle is not blocked or the spray hose kinked. • Pump valves may be stuck or blocked. Apply a small amount of pressure to the suction line by removing the filter and placing a garden hose over the suction hose inside the tank while the pump is running. • Voltage drop/restriction causing excessive heat. Check that voltage at pump is 12V when operating. Remove extended power loom if required or use heavier gauge wire. • Pumping at maximum pressure will use more amps and generate more heat. Check nozzle for restriction • When ambient temperature is over 21°C all pumps operating at higher pressures will have additional trouble to keep cool. If spraying on hot day consider using for shorter periods of time or pumping at lower pressure. Pump it getting very hot in

• Check if fitting is loose • Washer/gasket belonge between fittings; Check that part has not been lost.
