PSP Power Sprayers
Ref: PSP, PSPNG, PSPRG, PSPMN & PS22
DESCRIPTION
The PSP sprayer is mounted on a three-wheel robust tray chassis. The two
leading wheels are pneumatic; the rear castor wheel acts as a line marker. The
pump is a 12v diaphragm pump powered by its own integral battery. A charger is
supplied with each machine. A pressure gauge and a bypass regulator are fitted
for the hand lance.
The handles are adjustable to suit the operator. A tow bar is supplied with
each machine.
The average spray time per battery charge is approximately five hours, normal
spray use (3.5 hours intermittent) is for continuous spraying obviously,
on/off time, refill and movement actions will enhance overall spray time.
PSPNG – This version of the sprayer is specially designed to pass through
narrow 450mm (18″) seed beds.
PSPRG – Where the sprayer is to be used on rough, uneven ground, four large
400 x 8 wheels have been fitted.

PREPARATION FOR USE
- Place the front mounting boom kit to the front of the sprayer. Make sure that the boom mounting hose fixings are at the top.
- Push the bracket into the mounting and secure it with a black thumb screw.
- Fix the black delivery hose with a quick-fit coupling onto the sprayer boom.
- Fix the boom to the boom mounting bracket. Make sure the two arms on the boom are facing backward towards to sprayer. The boom should be parallel to the ground.
- Fix the battery terminals to battery (Red +, Blue -)
- Adjust the handle to a convenient height; at the same time make sure that the back two-pin plug is inserted into the holder.
TOWING MODE
Important: The PSPNG does not have a towbar.
- Place the boom onto the sprayer as directed above.
- Insert the tow bar supplied with the unit, making sure the clevis hook is in position furthest from the ground.
- Loosen the handle and put in an upright position
- The sprayer can now be hitched to the tractor, The tip of the nozzle facing the ground should be between 150mm – 200mm (6” – 8”) from the ground.
SPRAYING
-
To commence spraying the switch on the toggle switch situated to the righthand side of the handle.
-
The spraying pressure may be adjusted by turning the red knob situated to the right-hand side of the pressure gauge.
Hand Spraying – -
Switch off the sprayer
-
Remove the quick-fit coupling from the boom holder.
-
Connect the delivery hose to the brass trigger lance
-
Switch on the main switch (right-hand side of the handle) the pump will build up pressure and shut down.
-
When the trigger lance is depressed, the pump will start up and spraying can commence.
When removing the trigger lance from the quick-release coupling you must first release any pressure in system by switch off the pump and squeezing the hand lance trigger.
TROUBLESHOOTING
- If the pump fails to operate: – Check the electrical connection
- If the pump fails to deliver: –
– Check suction hose is in correct position.
Check the filter head of pump is clean.
Check the ‘O’ ring on filter bowl is in position.
If the boom is fitted make sure the nozzles & filters are clear. Check the lance handle is clean by unscrewing the brass barrel, also ensure the nozzle & filter are clear.
MAINTENANCE
The tank – Flush the machine through with clean water after use. Wash out
thoroughly twice a year.
The pump – An inlet filter is fixed to the head of the pump. To clean unscrew
the see-through filter bowl and clean. It is very important that on reassembly
you place the black ‘o’ ring seal in the correct position and re-fit the bowl.
Spray nozzles – Make sure they are spraying in an even pattern. There is a
filter behind each nozzle which may require cleaning.
Chassis wheels – Grease twice a year
Thumb Screws – Remove twice yearly and insert into grease and replace
General – Check over for tightness of fixings and fittings A light spray over
with preserving oil in the ‘off-season will prolong the sprayer life.

CALIBRATION
Calibrate as directed by the chemical manufacturers’ instructions
A SIMPLE GUIDE TO CHEMICAL / FEED APPLICATION
If the area to be sprayed is 3000 sq. meters. and according to the
instructions of the liquid bottle you select says sufficient for 1000 sq.
meters. Put 3 bottles in the tank and go over the area (north/south,
east/west) until the tank is empty.
Please note that having tested your sprayer with water as advised you may not
require a full tank of the mixture. Therefore, adjust requirements
accordingly.
UNDERSTANDING CALIBRATION
The law requires some 30,00 contractors and employed persons involved in
pesticide applications to obtain a Certificate of Competence.
This person will receive a good grounding in the safe and efficient use of
pesticides. The exemption rules are such that there will be a large pool of
people applying pesticides who, at best, will not have undertaken recent
training. A few far-sighted employers have incurred not inconsiderable costs
by including all their employers on the training courses and will more than
recoup on this investment over the years in increased efficiency.
Why Calibrate?
It is now a legal requirement for all users to adhere to the label
recommendations with regard to dosage rates, method of application, etc.
Besides being illegal to exceed the maximum recommended dose, getting the
application rate wrong can have distinctly adverse effects on the cash flow
and budgets.
Consistent overdosing of sites is not only environmentally undesirable; it
also increases the risk of damage to non-target species and runs- of damage in
more sensitive areas. It can, even with a modest spraying program, cost
hundreds of pounds each year in wasted chemicals and unnecessary losses.
Underdosing, on the other hand, can be equally costly. If weeds, for example,
are not controlled at the first application, a second later application may be
necessary. This may involve higher rates, a more expensive chemical or even
hand weeding. Add to this the disruption to work schedules and it becomes
evident that careful monitoring and control of all application programs is
essential.
Correct application and efficient monitoring is only possible if all personnel
involved have a thorough understanding of calibration techniques.
TERMINOLOGY
Treated Area
All chemical data, whether in advisory leaflets or label recommendations, is
stated in litre or kilograms of product per treated area. The actual area to
be treated thus has to be calculated for budgeting, purchasing, job planning
and calibration purposes.
Overall Application
The treated area is equal to the gross area
Band Application
The treated area is less than the gross area and is calculated thus:
Bandwidth x Band lengths x No of bands
Spot Application
The treated area is significantly less than the gross area and is calculated
thus: Area of spot = 0.7855 x (diameter) ² (meters) (derived from πd ²) 4
Treated area (ha) = Area of spot x No of spots per ha ÷ 10,000 Quite
obviously, the smaller the area that can be treated to achieve the desired
result; the less costly the operation. With the area calculated, the variables
involved can be determined in order to calibrate equipment to complete the
spraying operation in a safe and efficient manner.
Forward Speed
With overall and band applications, control of forwarding speed is critical in
determining how much chemical is applied. This will vary with the type of
terrain and must be realistically calculated. In flat terrain where unimpeded
progress is possible, forward speed will be greater than in undulating,
heavily vegetated conditions. In the latter, trial may be necessary to
determine a constant work rate, which can be, maintained both up and downhill.
Swathe width
The width covered at each pass is known as the swathe width and will vary
with, for example, choice of the nozzle, operating pressure and height of
application. Having selected the appropriate nozzle and operating pressure the
height selected must in the case of hand-held equipment be comfortable for the
operator.
Equipment is comfortable for the operator. With non-pressurized equipment,
such as CDA and gravity systems, there are obviously no operating pressures to
worry about.
Nozzle Output
Nozzle output is critical in all spraying operations and it is important to
select a nozzle type appropriate to the viscosity of the concentrate being
applied/swathe width required.
Flow Rate Flow rate will vary with nozzle type, viscosity, pressure, and the
ambient temperature at the time of application.
After selecting the most appropriate nozzle for the operation adjustment to
pressurize equipment will be necessary to achieve the desired flow rate. Flow
rate in powered machinery can be controlled by engine speed and/or internal
pressure adjustment.
Application Rate
Spray coverage of the target being sprayed should be sufficient to give an
even application of the correct dose of pesticide on the area to be treated.
The manufacturer’s recommendations must be followed and where there is a
choice of options, i.e., high, medium, low, very low volumes, select the most
appropriate volume to achieve the desired result.
Tank Dilution
From the application rate, it is possible to calculate the amount of pesticide
required per full tank.
Pesticide per fill (litres) = Tank volume (litres) x Pesticide volume
(litres/ha ÷ Diluent’s volume (litres/ha)
CALIBRATION TECHNIQUE
Having determined the above, the next step is to calibrate the actual
equipment chosen to apply the required amount of concentration on the target
area.
Each type of application obviously has its own calibration method which must
be studied and closely followed, but in general, the following notes for
spraying equipment will hold good. It is most important to understand that
each applicator will vary slightly from others of the same type and
manufacture. Thus, each piece of equipment must be individually calibrated.
The selected nozzles should be filled with water and the correct operating
pressure selected. The output of each nozzle should then be measured by
spraying into a measuring jug for a set period of time, e.g., one minute, to
give the nozzle output in liters/minutes.
As output will vary from nozzle to nozzle, in boom equipment the output from
each nozzle should be checked. In larger boom equipment, at least four nozzles
should be checked- one from each section and the output calculated
accordingly. If nozzle outputs on boom equipment vary by more than 5%, the
faulty nozzles should be replaced.
If output varies by a small amount from the calculated output, with some types
of equipment, altering the operating pressure can rectify this. Where the
output varies by a large amount, the calibration calculations should be re-
checked and the nozzle type changed if necessary. With all equipment, the
application pattern is checked and swathe width is measured by treating an
area of dry soil, concrete, etc.
Once the actual output is known, the forward speed can be calculated, in the
case of liquid sprayers, thus: Forward speed (meters/hour) = Measured nozzle
output (litres/minute) x 600,000 x (no of nozzles) Volume rate (litres/ha) x
Swathe width (meters)
The equipment can then be filled with the recommended mixture of pesticides
and dilatants. Never add pesticide concentrate direct to an empty tank, always
half-fill the tank with dilatants prior to adding the concentrate and mix
thoroughly. A suitable test area. e.g., A 100m strip can be sprayed at this
speed. At the end of this the actual
application rate should be determined by topping up the tank using a measuring
jug. The forward speed can then be adjusted to ensure that the concentrate is
applied at the correct rate. The serviceability of the equipment can be tested
at the same time. Leaks are environmentally unacceptable and waste expensive.
Blockages lead to patchy results and both make efficient monitoring
impossible.
The full calibration process is only necessary when equipment has not been
used for a while, after servicing or after changes in nozzles and pressure are
made.
It is, however, good practice to check the actual application rate at the
commencement of each days work and after lunch. Adjustments can be made as
appropriate.
Each employee will require access to a stopwatch and tape measure in order
that they can monitor their own output. If resistance is met then this is a
good indication that the employee has not understood the reasons behind the
calibration process and further training is needed.
The process can be tedious but as operators become more familiar with the
techniques, the loss in application time is reduced and more than offset by
the improved results obtained. Much can, of course, be done by management to
simplify the task by the production of job sheets clearly setting out the
details of each task and providing space for records to be kept. These when
returned, can be filed and the statutory requirement for adequate records to
be kept met.
MANAGEMENT TASKS
- Analyze the objectives of the operation
- Select the most effective chemical to achieve these objectives
- Check the manufacturer’s recommendations to ensure that it is suitable for the task and select an appropriate application rate
- Select the most efficient equipment to apply the chemical
- Calculate the dilution rate per tank: Pesticide per fill =Tank volume (1) x Pesticide rate (1/ha) ÷ Dilatant’s rate (1/ha)
- Select an appropriate tank pressure for pressurized equipment
- Select the correct nozzle to give the required swathe width
- Calculate the gross area
- Calculate the ACTUAL area to be treated. Overall application: Treated area = gross area Band application (ha): Treated area = Bandwidth (m) x Band length x no of bands Width between row (m) Spot treatment (ha): Treated area = [0.7855 diam² (m)] x no spots/ha ÷ 10,000
- Calculate an optimum forward speed based on the equipment to be used, the terrain type , and the ease of movement
- Issue comprehensive yet simple instructions to staff
- Ensure that a record of the operation and its effectiveness is kept and any problems investigated fully
SUPERVISORS TASKS
- Read notes provided and check details
- Check weather including wind speed and re-schedule operation if unsuitable conditions prevail

- Fill the sprayer with water and set to the correct pressure
- Measure nozzle flow rates using a measuring jugNozzle output (1/min) = quantity of spray in jug (ml) x 60,000 ÷ Time (sec)
- Adjust pressure to give calculated output (if possible). If significant variation from the calculated output, check calibration calculations and, if necessary, change nozzles
- Spray an area of concrete or dry soil to determine the actual swathe width and for an even droplet pattern. With boom equipment ensure that the spray pattern from each nozzle overlaps correctly
- Check for leaks and blockages. Blockages should only be cleared by using compressed air and never with wire!
- Using the actual nozzle output and the actual swathe width to determine the actual forward speed required to apply the correct quantity of chemical Forward speed = Nozzle output x 600,000 x No of nozzles ÷ Volume rate x swathe width

- Mark out an appropriate test area, spray, and calculate the actual application rate. Adjust the forward speed as appropriate
- Issue clear and simple instructions based on the actual output of the equipment
- Monitor the operation and ensure that regular checks on output are made
- Ensure that tank washings and surplus chemicals are disposed of safely in accordance with the law
- Ensure that adequate records are maintained on the basis of the actual operating parameters
Duplex Il Industrial Series Low Pressure (30 to 60 PSI)
INSTALLATION & SERVICE INFORMATION DESCRIPTION
FLOJET Industrial Duplex ll Pumps are designed for a wide range of
applications and are constructed from a selection of materials suitable for
handling a broad range of chemicals. The Duplex il series of diaphragm pumps
are self-priming and can be run dry without harm. They are intended for
intermittent duty cycles but can be run continuously for short periods of
time. The higher the duty cycle the shorter the expected life of the pump.
Typical pump uses are liquid transfer, spraying, cooling, circulation,
filtration and dispensing.
OPERATION
To start and prime the pump. the discharge line must be open allowing trapped
air to escape thus avoiding the potential of the airlock. The pressure switch
will shut off the pump automatically when the discharge valve is closed and
the pressure has risen to the switch OFF set point. The pressure switch will
restart the pump when a vaive is opened
and the discharge line pressure drops to the ON set point of the pressure
switch.
DEMAND OPERATION (INTERMITTENT DUTY)
Demand Operation is considered an “intermittent duty” application. The maximum
intermittent duty cycle is that which will cause the motor to reach its
maximum thermal limits. Once the maximum thermal limit is reached, the motor
must be allowed to settle to a lower temperature ideally being ambient before
resuming operation. Running the pump at or near the maximum thermal limit for
an extended period of time will shorten the life of the pump and may result in
immediate pump failure.
BYPASS OPERATION (IF EQUIPPED)
Models equipped with an external bypass system are designed to pump at high
pressures while at low or high flow rates. Models equipped with a bypass only
will continue to run until the power is manually turned off. The Duplex Il
pumps are not recommended for continuous duty service due to limited motor
brush life. Operation at lower pressures and temperatures, however, will
extend overall pump service life.
MOUNTING
The FLOJET Duplex Il Series pumps are self-priming. Vertical prime may vary
depending on the fluid viscosity, suction tube size. foot valve and pump
configuration.
The pump should be mounted in a dry and adequately ventilated area. If mounted
within an enclosure, provisions to cool the motor may be necessary.
PREVENTATIVE MAINTENANCE TIPS
If pumping a liquid other than water the pump should be flushed with water (if
applicable) after each use.
Sealers and Teflon tape acting as a lubricant can cause cracked housings or
stripped threads due to over-tightening. Care should be used when applying
sealers; the tape
may enter the pump inhibiting valve action, causing no prime or no shut-off
conditions. Failures due to foreign debris are not covered under warranty.
Before freezing conditions occur, the pump must be liquid-free or winterized
with proper anti-freezing chemicals.
If mounting the pump in an outdoor environment the pump should be shielded
from water, dust, sunlight, and wash-down spray.
Do not assume chemical compatibility. If the fluid is improperly matched to
the pumps Elastomers, the pump may fail to prime, have low pressures or the
pressure switch may
not shut off.
PLUMBING
Use a flexible hose of the correct pressure rating that is compatible with the
fluid to be pumped. Tubing should be a minimum of 3/8” (9.5 mm) ID and at
least 20 inches (508 mm) in length to avoid excess stress on the pump ports.
Do not crimp or kink the tubing. The pump head maybe rotated in 90° increments
to simplify plumbing.
FLOJET does not recommend the use of metal fittings, standard plastic male and
female threaded fittings can be acquired at commercial plumbing supply stores.
FLOJET also
distributes plastic barb fittings through our distributors (form no.
F100-001). The use of check valves in the plumbing system could interfere with
the priming ability of the pump. If a check valve is installed in the plumbing
it must have a cracking pressure of no more than 2 PSI (.14 bar). Use of a
minimum 40-mesh strainer or filter in the pump inet line will prevent foreign
debris from entering the system. Failures due to foreign debris entering the
pump will not be covered under the limited warranty.
Note: Inlet pressure must not exceed 30-PSI (2.1 bar) maximum.
WARNNG
Risk of an electrical shock!
When wiring electrically driven pumps, follow all electrical and safety codes,
as well as the most recent National Electrical Code (NEC) and the Occupational
Safety and Health
Act (OSHA).
Make certain the power source conforms to the pump voltage. Be sure all power
is disconnected before installation.
The pump should be wired into an individual (dedicated) circuit. controlled
with a UL/C-UL certified double pole switch rated at or above the fuse ampere
indicated on the
pump motor label.
On 115-volt AC pumps, the black wire lead is live or common, the white lead
wire is neutral and the green/yellow is ground. On 230-volt AC pumps the brown
wire lead is
live or common, the blue wire is neutral and the green/yellow is ground. On 12
and 24-volt pumps the red lead is positive and should be connected to the
battery plus (+) terminal. The black lead is ground and should be connected to
the battery minus (-) terminal. Use T6 AWG wire minimum. Use a fuse to protect
the system wiring and components. improper duty cycle and/or rapid start-stop
conditions caused by undersized spray nozzles will cause the internal thermal
breaker (if equipped) to trip, or can cause premature motor failure due to
excessive heat.
WARNING DO NOT USE TO PUMP FLAMMABLE FLUIDS, GASOLINE, KEROSENE FUEL OIL,
ETC. DO NOT USE PUMP IN A EXPLOSIVE ENVIRONMENT.
