Installaon and Service Informaon
Fimco High-Flo Pro Series pumps are designed to pump water and diluted chemicals for liquid applicaon with increased durability
over standard pumps. They are not designed to pump ammable materials. They are not designed to pump bleach soluons. Use
of this pump for bleach soluons will void the warranty. When pumping liquids other than water, the pump should be ushed
out with a cleaning soluon, such as Fimco Tank Neutralizer & Cleaner, or clean water mixed with a good grade dish soap aer
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. Vercal prime will depend on the viscosity of the liquid and sucon line size. Minimum
recommended sucon line size is 1/2 inch inside diameter hose. All hose connecons need to be ght or air leakage will break the
prime and disrupt water ow. The installaon 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 venlated area. The
pump can be mounted horizontally or vercally. If mounted vercally, 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 conguraons. 1/2” MNST pipe
thread connecons 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 connecons. Do not compress the feet. Overghtening will reduce the ability to isolate vibraon & noise.
Your pump is rated at 2.2 GPM @ open ow. If the discharge plumbing is very restricve or nozzle ps are undersized, the back
pressure will cause the pump to cycle rapidly. This rapid cycling will increase the operang 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 baery of your ATV, lawn tractor, or other vehicle with a 12V system. If using a stand alone
baery, use a deep cycle RV or marine baery.
The pump should be winterized before storage, by pumping a soluon of RV anfreeze through it, and the enre plumbing system.
