I wasn't sure this was going to work but knew I didn't want to use an A/C booster pump with an inverter. So this system uses a 12v LifePO4 battery with solar and a standard well pressure switch to kick the pumps on an off. I believe most problems people have with this pump is related to the included pressure switch so I bypassed it and use a standard well switch which is much more robust. I am using this pump in parallel with another smaller Seaflo pump (55 Series 5.5gpm 60psi). This larger pump (53 Series 7.0gpm 60 psi) is strong and is continuing to pump good where the smaller pump is starting to leak and the GPM seems to have reduced. To be fair the larger pump is advertised as "continuous" duty and these pumps are normally used in RV setups that aren't as demanding. I plan to replace the smaller pump with this larger pump and then I will then have two 7.0gpm pumps in parallel which will make this system even better. The two current pumps can usually keep up with all household demands, even multiple showers running while doing laundry. They only struggle if we are doing laundry and then also using multiple hoses around the house to water plants. Just to be clear these are not being used with sprinklers but all other household demands. My sprinkler are running off my well pump system. This system has allowed me to run my well pump less often and also gives me a few hundred gallons of water that can be used even during power outages. Like I said, I wasn't sure this was going to work by two years later and this little pump is still going strong. Review: Awesome Pump, that's not awesome. - Absolutely horrible pump. I added it to a Newmar Dutch Star 3852 bus. It cycles so hard it shook everything. The pressure goes from super strong to nothing back to super strong. The flow is as inconsistent as a uti. Showers were fun, after a total loss of pressure, when it came back it could be ice cold or super hot. Faucets worked the same way. It must drop to like 10 psi before it kicks in and starts pumping. Super loud. Finally got a warm spell, 30 degrees. I swapped it with a shurflow and everything is wonderful. I was they had a 70 psi pump. I wish this was as good as it was hyped up to be. I checked for leaks. I did a vinegar flush and a bleach flush. It didn't change a thing. Bad pump for rvs, or anything for that matter. Think broken super soaker. ## Features - βœ”οΈ [ SPECIFICATIONS ]:βœ”οΈ Model Number: SFDP1-070-060-53βœ”οΈ Voltage: 12V βœ”οΈ Open Flow: 7.0 GPM (26.5 LPM)βœ”οΈ Shut-Off Pressure: 60 PSI (4.2 BAR)βœ”οΈ Priming Capabilities: 6 feet (1.8 m) suction liftβœ”οΈ Material: EPDM (Valves) / Santoprene (Diaphragm)βœ”οΈ Ports: 1/2" NPT Pipe Threadβœ”οΈ Max Recommended Temperature: 140Β°F (60Β°C)βœ”οΈ Warranty: 4-Year Limited Warranty - βœ”οΈ [ HIGH VOLUME WATER FLOW ]: Produces up to 7.0 GPM (26.5 LPM), supporting systems with up to six fixtures for consistent water pressure in demanding applications. - βœ”οΈ [ INTEGRATED BYPASS SYSTEM FOR STABILITY ]: Maintains consistent pressure and prevents cycling during low water demand, reducing wear and ensuring smoother operation. - βœ”οΈ [ AUTOMATIC PRESSURE SWITCH FOR ON-DEMAND OPERATION ]: Activates the pump when water flow is needed and stops it when the demand ceases, providing seamless functionality. - βœ”οΈ [ DESIGNED FOR CONTINUOUS DUTY ]: Rated for extended use, making it reliable for heavy-duty applications such as agricultural water transfer, marine washdowns, and RV systems. - βœ”οΈ [ SELF-PRIMING AND RUN-DRY SAFE ]: Features a suction lift of up to 6 feet (1.8 meters) and can run dry without damage for flexibility in operation. - βœ”οΈ [ 1/2" NPT PIPE THREAD PORTS ]: Provides secure and reliable connections for ease of installation into various water systems. - βœ”οΈ [ BUILT FOR FRESH AND SALT WATER APPLICATIONS ]: Constructed with durable EPDM valves and a Santoprene diaphragm for corrosion resistance in freshwater and saltwater environments. - βœ”οΈ [ DURABLE DESIGN WITH 4-YEAR WARRANTY ]: Backed by SEAFLO’s 4-Year Limited Warranty for dependable performance and long-lasting protection. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08123KWCR | | Best Sellers Rank | #6,267 in Automotive ( See Top 100 in Automotive ) #3 in RV Water Pumps & Accessories | | Brand Name | SEAFLO | | Color | Black | | Customer Reviews | 3.7 3.7 out of 5 stars (81) | | Flow Rate | 7 Gallons Per Minute | | Global Trade Identification Number | 00810039490013 | | Item Dimensions L x W x H | 8.9"L x 6"W x 5.2"H | | Item Weight | 7 Pounds | | Manufacturer | SEAFLO | | Material Type | Stainless Steel | | Maximum Lifting Height | 6 Feet | | Model Number | SFDP1-070-060-53 | | Power Source | DC | | Product Style | 7.0 GPM - 60 PSI | | UPC | 608912739539 637776645700 | | Unit Count | 1.0 Count | | Voltage | 12 Volts (DC) | ## Product Details - **Brand:** SEAFLO - **Color:** Black - **Item Weight:** 7 Pounds - **Material:** Stainless Steel - **Maximum Flow Rate:** 7 Gallons Per Minute - **Maximum Lifting Height:** 6 Feet - **Power Source:** DC - **Product Dimensions:** 8.9"L x 6"W x 5.2"H - **Style:** 7.0 GPM - 60 PSI - **Voltage:** 12 Volts (DC) ## Images ![53-Series DC Diaphragm Water Pump – 7.0 GPM, 60 PSI, 12V | Heavy-Duty, Self-Priming, Bypass with Pressure Switch, Continuous Duty, 4-Year Warranty - Image 1](https://m.media-amazon.com/images/I/71FiQbLAgSL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Supplying water for two houses, still going strong 2 years later! *by C***R on September 29, 2024* I have a solar powered setup that takes water from a 1,000 gallon tank that then uses this pump and another to pressurize a small 44 gal pressure tank to then supplies the water for two houses on my property.
