![]() ![]() The pump may fail to prime, leak, have low pressures If the fluid is improperly matched to the pumps Elastomers, Units are NOT designed for permanent residential domestic water applications. Only pumps with Santoprene / EPDM elastomers are recommended for potable water. Temperature, aeration, concentration, and other factors may change the effect of the specific fluid on the pump materials. No warranty, expressed or implied, can be extended by the equipment manufacturer where failure is caused by chemical attack on pump materials. Suitability for the application should be determined by actual use and is the full responsibility of the buyer. Are Flojet pumps recommended for permanent residential domestic water applications? Units are NOT designed for permanent residential domestic water applications.Flojet 4.9 GPM Quad II Automatic 12 Volt DC, 45 PSI, Self Priming Demand Water Pumps are designed for a wide range of applications and are constructed from a selection of materials suitable for handling a broad range of products. What diaphragm and valve materials are recommended by Flojet for potable water? Only pumps with Santoprene / EPDM elastomers are recommended for potable water. Running the pump at or near the maximum thermal limit for extended period of time will shorten the life of the pump and may result in immediate pump failure. Once the maximum thermal limit is reached, the motor must be allowed to settle to a lower temperature ideally being ambient before resuming operation. What is an intermittent duty cycle? The maximum intermittent duty cycle is that which will cause the motor to reach its maximum thermal limits. What is meant by demand operation? Demand Operation is considered an “intermittent duty” application. The off-time should be the same or more than the run time. Up to 20 minutes when the discharge pressure is over 20 PSI. What does short periods of time mean? Up 60 minutes with discharge pressure of up to 20 PSI. The higher the duty cycle the shorter the expected life of the pump. Can Flojet Pumps run continuously? Can be run continuously for short periods of time. Can be run continuously for short periods of time. Questions & Answers What is the Flojet Pumps duty cycle? The Flojet manual states Intermittent duty.
