CE & RoHS Certified : Sports & Outdoors Review: More quiet than the others - Good pressure and seems a little higher quality than all the other brands. Review: So quiet! I didn’t know what I was missing!! - Oh my god. I should have bought this for my camper 5 years ago. I cheated out in 2020 and bought a super cheap $20 water pump. It shook so loud and violently I was embarrassed at campsites to even turn it on. Finally got around to buying this pump and accumulator combo. Holy crap it’s silent!!!! About as close to silent as a pump could get. It’s mounted in the back of a campervan under the bed and when running the sink I cannot hear it. It’s wall mounted as well and doesn’t vibrate anything. The zero vibration is definitely due to the mounting plate. It has rubber shock absorbing feet attaching the pump and accumulator to the plate. And the plate has a second set of rubber shock absorbers on water you mount it to. 10/10 would recommend this as an upgrade if you want a quieter pump. Been running this for about 4 months so far and I love it. ## Features - [ SPECIFICATIONS ] Model: SFWSK1-030-045-002 | Voltage: 12V DC | Open Flow: 3.0 GPM (11.3 LPM) | Tank Volume: 0.2 Gallon (0.75 L) | Pressure Off: 45 PSI (3.1 BAR) | Pressure On: 35 PSI (2.4 BAR) | Priming Capability: Self-priming up to 6 feet (1.8 m) suction lift | Max Draw: 11.0A | Ports: 1/2" MNPT | Material: EPDM valves / Santoprene diaphragm - [ REDUCES CYCLING WITH ACCUMULATOR TANK ] The 0.2-gallon accumulator tank minimizes pump cycling, ensuring steady water pressure, quieter operation, and longer pump life by reducing wear and tear on internal components. - [ POWERFUL PERFORMANCE FOR MULTIPLE FIXTURES ] With a 3.0 GPM flow rate and 45 PSI shut-off pressure, this pump is capable of simultaneously supplying water to up to three fixtures, making it perfect for boats, RVs, cabins, and tiny homes. - [ DURABLE CONSTRUCTION FOR LONGEVITY ] Built with EPDM valves and a Santoprene diaphragm, this system withstands harsh conditions, providing corrosion resistance and consistent performance in marine, RV, and off-grid environments. - [ EASY INSTALLATION & VERSATILE MOUNTING ] The system comes pre-assembled and is ready for installation, with horizontal or vertical mounting options for effortless setup in new or existing water systems. - [ ULTRA-QUIET OPERATION ] Engineered for silent performance, the heavy-duty corrosion-resistant motor and precision design reduce noise, creating a smooth and quiet water pressure experience. - [ SAFE FOR DRINKING WATER APPLICATIONS ] Constructed with materials that meet potable water safety standards, this system is ideal for drinking water systems in RVs, boats, tiny homes, and off-grid setups. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B081544YH8 | | Best Sellers Rank | #40,420 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #4 in Boat Water Pressure Pumps | | Brand | SEAFLO | | Brand Name | SEAFLO | | Color | Black | | Customer Reviews | 4.6 out of 5 stars 301 Reviews | | Flow Rate | 3 gpm | | Global Trade Identification Number | 00810039490020 | | Included Components | 51F09 Fitting | | Item Dimensions L x W x H | 14.57"L x 10.24"W x 5.75"H | | Item Weight | 6 pounds | | Manufacturer | SEAFLO | | Manufacturer Part Number | SFWSK1-030-045-002 | | Manufacturer Warranty Description | 4-Year Warranty | | Material | Polypropylene (PP) | | Material Type | Polypropylene (PP) | | Maximum Lifting Height | 6 feet | | Model Number | SFWSK1-030-045-002 | | Number of Items | 1 | | Number of Packs | 1 | | Power Source | 12V DC | | Product Dimensions | 14.57"L x 10.24"W x 5.75"H | | Product Style | Diaphragm Pump | | Style | Diaphragm Pump | | UPC | 793945656622 810039490020 | | Unit Count | 1 Count | | Voltage | 11.99 volts | ## Product Details - **Brand:** SEAFLO - **Color:** Black - **Item Weight:** 6 pounds - **Material:** Polypropylene - **Maximum Flow Rate:** 3 gpm - **Maximum Lifting Height:** 6 feet - **Power Source:** 12V DC - **Product Dimensions:** 14.57"L x 10.24"W x 5.75"H - **Style:** Diaphragm Pump - **Voltage:** 11.99 volts ## Images ![33-Series Water Pump and Accumulator Tank System - 12V DC, 3.0 GPM, 45 PSI, 0.2 Gallon Tank - Reduces Cycling For Marine, Boat, RV, Off-Grid Applications- 4-Year Warranty!

So that being said the 12 volt DC pump should operate safely with a power (voltage) source of 10.5 to 13.5 volts DC, so you 24 volts DC would MOST CERTAINLY cause serious damage to the pump motor. Insco Electric makes it Buck and Boost transformer for less than $10.00 that would be a safe and inexpensive fix, or you could use a Diode, witch would be more difficult to incorporate one into a safe enclosure and power connection. Good Luck **Q: Is there a version of this that runs on regular 110?** A: Yes, you can get 110 volt pumps with accumulator to do the same thing on 110 power.

I didn’t know what I was missing!! *by A***E on October 13, 2025* Oh my god. I should have bought this for my camper 5 years ago. I cheated out in 2020 and bought a super cheap $20 water pump. It shook so loud and violently I was embarrassed at campsites to even turn it on. Finally got around to buying this pump and accumulator combo. Holy crap it’s silent!!!!

Been running this for about 4 months so far and I love it. ### ⭐⭐⭐⭐⭐ Replaced Joolca *by K***Y on September 21, 2025* For $100 either I buy this or a replacement OEM Joolca pump, I went this route instead to see what it will provide as an alternative or an upgrade. So far it has been an upgrade. I did have to make some modifications but I have run into the hardware store and buying some 1/2-inch to NPT adapters, because it only comes with one side while I needed two for the Joolca, input and output sides. After that was done it was flawlessly. I also love that it is going to provide pressure and that gives you the ability to use very little pressure in order to get some very nice sustained drizzle or water flow. That's much better than what came with the OEM. It's a really nice setup even though it does take up a bit more space. I've made room in my compartments for this because I like it that much. ## Frequently Bought Together - SEAFLO 33-Series Water Pump and Accumulator Tank System - 12V DC, 3.0 GPM, 45 PSI, 0.2 Gallon Tank - Reduces Cycling For Marine, Boat, RV, Off-Grid Applications- 4-Year Warranty!
