Installaon and Service Informaon
Fimco High-Flo Gold Series pumps are designed to pump water and aqueous solutions of common pesticides. They are not
designed to pump petroleum products or other flammable materials. They are not designed to pump bleach solutions. Use of this
pump for petroleum products or bleach solutions will void the warranty. When pumping liquids other than water, the pump
should be flushed out with clean water after each use to prolong pump life.
High-Flo Gold Series pumps are equipped with a demand switch that reacts to outlet pressure and shuts the pump motor off at a
factory set pressure limit of 45 PSI. When the pressure drops below this preset limit the switch allows the pump motor to start again.
High-Flo Gold Series pumps are self-priming. Vertical prime will depend on the viscosity of the liquid and suction line size. Minimum
recommended suction line size is 3/8 inch. All hose connections need to be tight or air leakage will break the prime and disrupt water
flow. The installation of a 50 mesh strainer is recommended to prevent debris or other foreign material from entering the pump and
causing pump failure. The pump should be mounted in a dry and adequately ventilated area. The pump can be mounted horizontally
or vertically. If mounted vertically, the pump head should be down and the motor should be up. Your pump will come with adapters
which will allow you to hook up to various plumbing configurations. These fittings push into the ports of the pump and a slide mecha-
nism ‘locks’ them into place. Use flexible hose or tubing to connect to the inlet and outlet ports on the pump. This minimizes stress on
the pump head. Never use rigid pipe connections. Do not compress the feet. Overtightening will reduce the
ability to isolate vibration & noise.
Your pump is rated at 3.8 GPM @ open flow. If the discharge
plumbing is very restrictive or nozzle tips are undersized, the
back pressure will cause the pump to cycle rapidly. This rapid
cycling will increase the operating temperature of the motor
and the amperage draw on the power supply. Extended use
with this cycling will cause premature failure of the pump.
Your pump is designed to run off of the battery of your ATV,
lawn tractor, or other vehicle with a 12V system. If using a
stand alone battery, use a deep cycle RV or marine battery.
The pump should be winterized before storage, by pumping a
solution of RV antifreeze through it, and the entire plumbing
system.
Warranty:
Your Fimco High-Flo Gold Series pump is warranted for
one year from date of purchase for homeowner use & 90
days for commercial use, against manufacturer or work-
manship defects. Warranty claims will be processed by
Fimco Industries after the item is returned, freight prepaid,
to the Fimco Industries facility.
Pump must be flushed of all chemicals prior to returning to
Fimco. Fimco Industries assumes no liabilities for any
unwarranted equipment. Any unauthorized modifications/
alterations of the returned product will void your warranty.
All items must be returned within 30 days of failure. Ex-
penses, inconveniences, loss of chemicals, or other dam-
ages that occur, are not subject to warranty consideration.

DO
 Clean and rinse your pump after each use with Fimco Tank
Neutralizer
 Winterize your pump or sprayer by rinsing, draining and
running RV Antifreeze through it before storing for the winter.
 Use clean water for your spray mixture
 Store inside a building when not in use.
DON’T
 Use to pump bleach.
 Use to pump petroleum products such as diesel fuel,
gasoline or kerosene
 Leave your pump sit with spray mixture in it for extended
periods
 Use dirty or unfiltered water for spraying
Troubleshooting the Pump:
Motor does not run:
 Check for loose wiring connection(s).
 Make sure the 'ON/OFF' switch in the lead wire assembly is
in the 'ON' position. "I" is the 'ON' position and 'O' is the 'OFF'
position.
 Check for defective pressure switch. Make sure you are con-
nected to a good 12 volt power source. Make sure any on/
off switches are in the 'on' position. Remove the cap to the
pressure switch. Pull both red wires off of their terminals, and
touch the two ends together. If your pump runs when you do
this, your pressure switch will need to be replaced.
 Check the fuse.
 Check for low voltage at the power supply.
Pump does not prime:
 Check for air leaks in supply line.
 Check for debris in the check valve assembly.
 Check for defective check valve.
 Check for clogged strainer/filter.
 Check for cracks in the pump housing.
 Check for empty product supply.
Pulsating flow (surging):
 Check for defective pressure switch.
 Check for leaks in the discharge line.
 Check for restriction in the discharge line.
 Check for debris in nozzle orifice.
 Discharge hose may be too long.
 Check for clogged strainer.
Motor continues to run after discharge is shut off:
 Check for empty product supply.
 Check for open bypass valve. (if equipped)
 Check for low voltage.
 Check for leak in discharge line.
 Check for defective or dirty check valve.
 Check for defective pressure switch.

Checking the Pressure Switch:
If your motor is not running and you’ve checked the following: for loose wiring connections, fuse, the
switch on the lead wire was “ON” and made sure you were connected to a fully charged battery and
everything is fine, but the motor won’t run, then it’s time to check to see if the pressure switch is bad.
 Remove the cover off the 1” square box (pressure switch) on the head of the pump, the cover is
held on by one phillips-head screw. This will expose the two red wires.
 With the pump connected to a good 12 volt power source and everything on.
 Slip the two red wires off the terminals and touch them together.
If the motor runs, it means the pressure switch is bad and needs to be replaced.
If it still doesn’t run, try bypassing the switch in the lead wire or using another lead wire. Even if a
tester shows power to the pressure switch, it still could be the switch in the wire that is causing the
problem. If still not responsive, use a voltmeter or electrical tester to make sure you are getting power
to the head of the pump, as it could possibly be something in one of the wires or even the lead wire
assembly may need to be replaced.
Warning: It is NOT recommended to run the pump this way, as the pump will continue to run and not
shut off.
This could result in blown hoses when all discharges are closed. Also, this could result in premature
failure of the pump completely.
Cleaning the Check Valve:
If you’re experiencing little to no pressure or the pump is not priming and you’ve checked your filter
screen and it’s clean, you may need to clean the check valve.
 Remove the head of the pump, which is held on by about 6-7 screws.
 The first piece inside the head of the pump is called a check valve, it’s the part responsible for building up pressure and
pumping water/solution through the lines.
 Clean the check valve under hot, soapy water (such as a good grade dish soap).
 Give it a very light scrubbing with something like an old toothbrush, something with soft bristles.
 Then let it soak for about an hour or so in the hot soapy solution and replace in the pump and reassemble the
pump.
Most times this will restore most, if not all of the prime of a pump.
Try another 12-Volt battery
Quarter turn at a time clockwise until surging stops
Check that shut-off valve on inlet (if applicable) is open
Troubleshooting
Pump will not run:
Check for loose wiring
Make sure the ON/OFF switch is on
Check the fuse
Check for defective pressure switch
Low Pressure/Low Flow:
Check for a clogged strainer
Check for proper voltage
Check for worn or dirty check valve
Pump surges:
Low flow may cause pump to surge
Spray wand is adjusted for a small or fine spray pattern
Slightly open bypass (if applicable) to overcome
If needed, pressure switch may need to be adjusted
Pump continues to run:
Bypass (if applicable) is not completely closed
System has leaks
Check for worn or dirty check valve
Fuse blows:
Excessive voltage
Improper adjustment of pressure switch
Damaged or defective wiring harness
Defective pressure switch
