The Fimco High-Flo High Performance diaphragm pump is designed for efficient and reliable fluid transfer, primarily for water and aqueous solutions of common pesticides. It is explicitly not intended for use with petroleum products, bleach solutions, or other flammable materials, as such usage will void the warranty and can lead to premature pump failure.
This pump operates on a 12-volt system, making it suitable for use with ATV, lawn tractor, or other vehicle batteries. For standalone applications, a deep cycle RV or marine battery is recommended. The pump is self-priming, with vertical prime capability depending on the liquid's viscosity and suction line size. A minimum recommended suction line size of 3/8 inch is specified to ensure proper operation.
A key feature of this pump is its integrated demand switch, which automatically reacts to outlet pressure. This switch is factory-set to shut off the pump motor when the pressure reaches 60 PSI. When the pressure drops below this preset limit, the switch reactivates the motor, ensuring consistent pressure and preventing continuous operation when not needed. This demand-based operation helps conserve power and prolong pump life.
The pump's design emphasizes robust fluid handling. It is recommended to install a 50-mesh strainer on the inlet to prevent debris and foreign materials from entering the pump, which could cause blockages and damage. All hose connections must be tight to prevent air leakage, which can disrupt the priming process and water flow.
The pump is designed for versatility in mounting, allowing for both horizontal and vertical installation. If mounted vertically, the pump head should be positioned downwards and the motor upwards. The pump comes with adapters that facilitate various plumbing configurations. These fittings are designed to push into the pump ports and lock into place with a slide mechanism. It is crucial to use flexible hose or tubing for connecting the inlet and outlet ports to minimize stress on the pump head. Rigid pipe connections are not recommended, and the pump's feet should not be compressed, as this can reduce its ability to isolate vibration and noise.
The pump's performance is rated at 4.5 GPM at open flow. However, if the discharge plumbing is overly restrictive or if nozzle tips are undersized, the back pressure can cause the pump to cycle rapidly. This rapid cycling can lead to increased motor operating temperature and higher amperage draw, which can result in premature pump failure if sustained. Therefore, proper sizing of discharge components is essential for optimal pump performance and longevity.
To ensure the longevity and proper functioning of the pump, several usage guidelines are provided. After pumping liquids other than water, it is imperative to flush the pump with a cleaning solution, such as Fimco Tank Neutralizer & Cleaner, or clean water mixed with a good grade of dish soap. This practice helps prevent residue buildup and maintains the pump's internal components.
For storage, especially during winter, the pump should be winterized. This involves pumping a solution of RV antifreeze through the pump and the entire plumbing system. This prevents freezing and potential damage to the pump and associated components. The pump should be stored in a dry and adequately ventilated area, preferably inside a building when not in use.
The manual explicitly warns against using dirty or unfiltered water for spraying, as this can introduce contaminants that may damage the pump or clog its components. It also advises against leaving spray mixtures in the pump for extended periods, as this can lead to corrosion or material degradation.
Regular maintenance is crucial for the pump's performance and lifespan. The manual provides detailed troubleshooting steps for common issues.
If the motor does not run, users should check for loose wiring connections, ensure the ON/OFF switch is in the 'ON' position, and verify that the pump is connected to a good 12-volt power source. A key troubleshooting step involves checking the pressure switch. This can be done by removing the cover of the 1-inch square box on the pump head, which exposes two red wires. With the pump connected to power, slipping these wires off their terminals and touching them together can determine if the pressure switch is faulty. If the pump runs when the wires are touched, the pressure switch needs replacement. The manual warns against running the pump this way for extended periods, as it will not shut off and can lead to blown hoses or premature pump failure.
For issues with the pump not priming, users should inspect for air leaks in the supply line, check for debris in the check valve assembly, and ensure the strainer/filter is not clogged. Cracks in the pump housing or an empty product supply can also prevent priming.
Low pressure or low flow issues can be addressed by checking for leaks or restrictions in the discharge line, debris in the nozzle orifice, or a clogged strainer. Verifying proper voltage and trying another 12-volt battery are also suggested.
Pulsating flow or surging can occur if the flow rate is low or if the spray wand is adjusted for a small or fine spray pattern. Slightly opening a bypass (if applicable) can help. If surging persists, the pressure switch may need a minor adjustment (a quarter turn clockwise at a time) until surging stops. Other causes include defective pressure switches, leaks or restrictions in the discharge line, debris in the nozzle orifice, or a discharge hose that is too long.
If the motor continues to run after the discharge is shut off, potential causes include an open bypass valve (if equipped), low voltage, leaks in the discharge line, or a defective pressure switch.
Fuse blows can indicate excessive voltage, improper pressure switch adjustment, damaged or defective wiring harness, or a defective pressure switch.
A specific maintenance procedure for cleaning the check valve is provided for situations with little to no pressure or priming issues. This involves removing the pump head (secured by 7 screws), extracting the check valve, and cleaning it under hot, soapy water with a soft-bristled brush. After soaking for an hour, the check valve should be reinstalled. This process often restores the pump's prime, but if issues persist, replacing the check valve is recommended.
The manual emphasizes the importance of retaining a copy of the purchase receipt for warranty validation. The pump is warranted against manufacturer or workmanship defects for two years for homeowner usage and 90 days for commercial usage from the date of purchase. The warranty does not cover used equipment, altered or improperly maintained equipment, normal wear and tear, or damage from misuse, accidents, or acts of God. It also excludes accessories, attachments, or rubber parts not manufactured by Fimco.
