Diaphragm Pump
Model: HFP-2.2
(5281325/5151075)
Installaon and Service Informaon
Fimco High-Flo Pro Series pumps are designed to pump water and diluted chemicals for liquid applicaon with increased durability
over standard pumps. They are not designed to pump ammable materials. They are not designed to pump bleach soluons. Use
of this pump for bleach soluons will void the warranty. When pumping liquids other than water, the pump should be ushed
out with a cleaning soluon, such as Fimco Tank Neutralizer & Cleaner, or clean water mixed with a good grade dish soap aer
each use to prolong pump life.
This High-Flo Pro Series pump is equipped with a demand switch that reacts to outlet pressure and shuts the pump motor o at a
factory set pressure limit of 100 PSI. When pressure drops below this preset limit the switch allows the pump motor to start again.
High-Flo Pro Series pumps are self-priming. Vercal prime will depend on the viscosity of the liquid and sucon line size. Minimum
recommended sucon line size is 1/2 inch inside diameter hose. All hose connecons need to be ght or air leakage will break the
prime and disrupt water ow. The installaon 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 venlated area. The
pump can be mounted horizontally or vercally. If mounted vercally, 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 conguraons. 1/2” MNST pipe
thread connecons will require pipe tape. Do not over ghten ngs causing extra stress, prematurely breaking the pump head.
Use exible 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 connecons. Do not compress the feet. Overghtening will reduce the ability to isolate vibraon & noise.
Your pump is rated at 2.2 GPM @ open ow. If the discharge plumbing is very restricve or nozzle ps are undersized, the back
pressure will cause the pump to cycle rapidly. This rapid cycling will increase the operang 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 o of the baery of your ATV, lawn tractor, or other vehicle with a 12V system. If using a stand alone
baery, use a deep cycle RV or marine baery.
The pump should be winterized before storage, by pumping a soluon of RV anfreeze through it, and the enre plumbing system.
WARNING: To reduce the risk of injury, the
user must read and understand the operator’s
manual before using this product.
WARNING: Cancer and Reproducve Harm.

2. Then disconnect the negave (black) connecon.
3. Finally disconnect from the posive (red) connecon.
NOTE: it is important to disconnect power to the pump when not in use for safety reasons.
Warning: Ensure the wiring harness does not become pinched or damaged in any way. This may damage the pump or cause the
wiring harness to overheat, resulng in a melt down or re.
The Pump will be Damaged and Warranty Voided if used to apply bleach, chlorine or gasoline, diesel, kerosene, oil).
Pump should not be used to transfer any product intended for human consumpon.
Do Not modify pump design.
Before Spraying:
Pump and Sprayer Prep: Always inspect and prepare the pump and sprayer before use.
Keep Pump O unl ready to spray in order to avoid unintenonal spray release.
Wind Speed. Never spray when wind exceeds 4 MPH, in order to minimize spray dri.
Keep Area Clear. Keep people and pets clear of area that is being sprayed.
During Spraying:
Follow Chemical Labels. To avoid over spraying.
Keep Area Clear. Keep people and pets clear of area that is being sprayed.

Maintenance During/Aer Spraying
Aer use, drain the tank and store or dispose of chemical properly. Fill the sprayer half way with clean water. Start the pump and
allow the water to pump through the enre plumbing system and nozzles. Drain and then rell half full, add the recommended
amount of a good quality tank cleaner, such as FIMCO Tank Neutralizer and Cleaner. Turn pump on and circulate through system
for 15 minutes and then spray out through handgun nozzle. Rell sprayer half way with clean water and repeat. Follow chemical
manufacturer’s disposal instrucons of all wash or rinsing water.
WARNING: Some chemicals will damage the pump valves if allowed to soak untreated for a length of me! ALWAYS ush the
pump as instructed aer each use. DO NOT allow chemicals to sit in the pump for extended mes of idleness. Follow the chemical
manufacturer’s instrucons on disposal of all waste water from the sprayer.
Winter Storage
Prepare the sprayer for end-of-season storage by running RV anfreeze through the system. This will keep internal parts lubricat-
ed, protect against corrosion and keep the unit from freezing. Note: RV anfreeze is non-toxic and biodegradable and generally
safer for the environment than automove anfreeze.
Before storing your sprayer for winter or long term storage, thoroughly clean and drain it as much as possible. Then pour enough
pink RV anfreeze into the tank so that when the pump is turned on you can pump the anfreeze throughout the enre plumbing
system, including the bypass. Make sure to operate the handgun unl you see pink uid spraying from the nozzle. Leave any
remaining anfreeze in the tank. Before your next usage, rinse the anfreeze from the sprayer with clean water.
It is nearly impossible to drain all of the water from the sprayer and any trapped water can freeze in cold weather and damage
parts of the sprayer. Pumping the anfreeze through the system will displace the water and help prevent this damage.
Removing from storage: drain the anfreeze. Fill the tank with fresh water and run through the system. Dispose of anfreeze and
ush water properly.
Sprayer and Pump FAQs:
 Why does the pump not run all the me?
This is an on-demand pump and only runs when a discharge is open (spray gun, bypass, boom (if applicable) or a leak is in the
system.
 Why does the pump surge while using the spray gun?
Low ow/high pressure may cause the pump to surge (or cycle). Typically the spray wand is adjusted at too ne of a mist, to
overcome, adjust the nozzle for a higher ow.
 How do I adjust the pressure?
Pressure can only be adjusted by opening the pressure adjust (bypass) valve to allow some of your water or soluon to return
to the tank (if equipped).
 Pump quit and will not run, what do I need to do?
Squeeze trigger on spray gun to ensure that the system isn’t just pressurized up with discharges closed.
Check electrical connecons, ensure switch is on. Check fuses. Check for proper voltage. Check pressure switch.
 Low ow or no ow at all, what do I need to check for?
Check for a clogged or kinked intake hose and/or clogged intake strainer. Check for proper voltage.
You will need to occasionally check your intake strainer to ensure that it is clean of any debris.
 What is causing the fuse to blow each me I turn the pump on?
Check for excessive voltage. Improper adjustment of the pressure switch. Damaged or defecve wire harness or defecve
pressure switch.
Warning: Ensure the wiring harness does not become pinched or damaged in any way. This may damage the pump or cause the
wiring harness to overheat, resulng in a melt down or re.
Before Troubleshoong or Aempng to Service the Pump:
 Review Troubleshoong Chart: Do Not aempt to repair unl steps below are followed.
 Personal Protecve Gear: Wear protecve gear when servicing pump.
 Disconnect Power: Disconnect the power to the pump and relieve the pressure from the system.
 Empty and Flush the pump system with water, never aempt to service the pump unl it has been emped and ushed.
 Perform Repairs: Follow direcons provided in the troubleshoong secon to repair the pump.
 Test: Always test the pump for leaks with plain water aer any repairs before using.

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. Refer to instructions
on next page.
• 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.
Low Pressure/Low Flow:
• Check for leaks in the discharge line.
• Check for restriction in the discharge line.
• Check for debris in nozzle orifice.
• Check for clogged strainer.
• Check for proper voltage—try another 12-volt battery.
Pulsating flow (surging):
• Suction leak may cause pump to surge.
• Spray wand is adjusted for a small or fine spray
pattern.
• Slightly open bypass (if applicable) to overcome.
• 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:

Checking the Switch Assembly:
If your motor is not running and you’ve checked the following: for loose wiring connecons, fuse,
the switch on the lead wire was “ON” and made sure you were connected to a fully charged
baery and everything is ne, but the motor won’t run, then it’s me to check to see if the
pressure switch is bad.
• Gradually pull on the white terminal connectors with pliers to remove from switch. A
jumper wire will be needed to jump the two connectors together.
• Connect pump to a good 12 volt power source and everything on.
If the motor runs, it means the pressure switch is bad and needs to be replaced.
Warning: It is NOT recommended to run the pump this way, as the pump will connue
to run and not shut o.
This could result in blown hoses when all discharges are closed.
Also, this could result in premature failure of the pump completely.
If it sll doesn’t run, try bypassing the switch in the lead wire or using another lead wire.
If sll not responsive, use a voltmeter or electrical tester to make sure you are
geng 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.
Cleaning the Valve Kit:
If you’re experiencing lile to no pressure or the pump is
not priming and you’ve checked your lter screen and it’s
clean, and you’ve gone through the other trouble
shoong ps, you may need to clean the valve kit.
• Remove the upper housing of the pump, which is
held on by 6 screws.
• The rst piece inside the head of the pump is called
a valve kit, it’s the part responsible for building up
pressure and pumping water/soluon through the lines.
• Clean the valve kit under hot, soapy water (such as a good grade dish soap).
• Swish the valve kit around a lile bit.
• Then let it soak for an hour in the hot soapy soluon and replace in the pump and reassemble
the pump.
Most mes this will restore most, if not all of the prime of a pump.
If you’re sll having issues with pressure aer this step, it would be recommended to replace this
