Pumps must be thoroughly flushed and drained before being taken in for service.MaintenanceTo keep the pump running at its best, periodically perform the following procedures:1.Check strainer for dirt accumulation. To clean strainer, remove inlet flange and pull out screen.2.Remove rotor cover and inspect vanes. Vanes should be replaced after excessive wear to preventdamage to pump. If more than 1/2 the total blade length extends out of the rotor slot at the extreme of travel, the wear is excessive.3.Check hose and nozzle for wear or damage. Bad hoses or nozzles are potential safety hazards.For FR611 see meter's Owner's Operation & Safety Manual for additional recommendedmaintenance procedures.Frequently Asked Questions1. My pump only pumps for a few minutes and then stops. What is happening?Generally "short cycling" indicates the motor is drawing too much current from the power source for some reason, and the thermal relay is opening to protect the insulation from the resulting heat build up. If this is what is happening, the thermal relay will reset after 10 to 20 minutes and the motor will again operate. The causes of high current are many. The pump is designed for low viscosity fluid, like diesel or gasoline, and will overheat if used to pump oil or other higher viscosity fluids. The inlet filter screen could be clogged.Bearings could be defective resulting in a drag on the motor shaft.See the Troubleshooting Guide in your Owner's Manual shipped with your unit or the copy available in the eLibrary.2. There is fluid leaking out of the small hole in the side of the pump body. How do I stop it?This small hole is described as the "weep hole" and is positioned to drain fluid that has leaked past the dynamic seal between the pump and the motor. It is important that the leak be corrected as soon aspossible to avoid damage to the motor. A new shaft seal will need to be installed.See the Troubleshooting Guide in your Owner's Manual shipped with your unit or the copy available in the eLibrary.3. What can I do to avoid my pump from losing prime when it sits for a time?Maintaining "prime" or keeping fluid in the inlet piping of your pumping system requires that no air leak into that piping. Do not open the nozzle while pump is off. If your pump is consistently losing prime, check all joints and fittings paying particular attention to the suction tube to pump connection, and the variouscovers and caps in the pump itself. Teflon® type sealing tape or a sealing compound noted as resistant to fuels is recommended at all threaded pipe connections.4. When it gets hot outside my pump will not pump gasoline but my diesel pump works great,whais going on?A suction pump works by developing a vacuum above the fluid being pumped and depending onatmospheric pressure to force the fluid into that vacuum. The higher the fluid is being raised, the more vacuum is required. If the fluid turns to a gas at a lower vacuum than that required to raise the fluid out of the container, the system is said to be vapor locked. In other words, rather than enough vacuum being developed by the pump to raise the fluid, the pump is instead vaporizing the gasoline and only gas vapor i being pumped. Diesel has a very low vapor pressure at even relatively high temperatures so there is no danger of vapor locking at practical temperatures. Gasoline is blended to have different vapor pressures to aid in winter starting (high vapor pressure) or avoid vapor locking in the summer (lower vapor pressure).The unit of measure used in the industry for this characteristic is Reid Vapor Pressure. Having winter gas (high Reid Vapor Pressure), still available in your tank in a warm spring, is a common cause of vaporlocking pumps.Once the situation exists, there are a limited number of options. Decrease the "lift" needed to raise the gasoline by filling the tank to the top is the easiest and quickest. This has the added benefit of mixing in a new blend of gasoline with a lower vapor pressure which will average the blended Reid Vapor Pressure down. Another option is to decrease the temperature by shading and/or cooling the piping and pump in some fashion. In an emergency spraying water on the piping could drop the system temperaturesufficiently to allow gasoline to be pumped. Use extreme caution when spraying water around。
