Installaon and Service Informaon
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.
