My backpack pump, which is of good quality but manual, blew the plastic piston on the pump and a new one was almost 35$!? I decided to look into adding a pump that could provide the output that the pumps wand could handle. This pump did the work! And whats more is that I didnt use the backback sprayer but a 55 gallon plastic drum I bought on marketplace. I attached a long sprayer feeding hose to it and put that down the drum. For power I pull this drum on an old cart I have (can only fill about 40 gallons before it starts tipping). I took a partial electrical cord and attachted one side to a nice ip68 switch and to the pump. then the other put small jumper clamps on so I could put it to my mowers battery. the tank now also has drip irrigation that I can turn on and passively pour out water. But I can also spot spray plants if I want or even strap the hose up top, lock it "on", and drive around my 6 acres spraying Humic and Fulvic acid water everywhere to improve the soil! The little pump has now run 40 gallons almost non stop in one sitting and ive probably sprayed another 50 gallons through it without a single issue. it has a feature where it gets to a specified internal pressure and shuts down until you drop that pressure. If it seems to be running continuously I recommend flowing it and its likely that there is just air in the lines not compressing like water causing this. Id highly recommend this if you want to push water in small tubing. It has a lot of nice functionality and runs easily off a 12v battery using off the shelp bits and bobs. Review: Both pumps (1.0 GPM) working GREAT for 2nd season! - The 1 GPM pump is EXCELLENT, especially at the price point around $20! I haven't metered the pressure, but the advertised 80 psi was noticably more powerful than my 60 psi HighFlo, and had to be turned down! It starts and stops smoothly. I bought two of them to power my 3 gallon pump up sprayers, so I didn't mind that the motor was open to the elements. If you are going to mount this on a larger sprayer that could get splashed or rained on, you may want the enclosed 1.2 GPM pump. Both pumps are working fine for the second season. ## Features - The patented design delivers smooth & consistent flow at all ranges of operation, while drawing low current; 3/8-inch hose barb ports; Vertical Suction Lift: 5ft (1.5m). CUT-OFF Pressure : default 80 PSI. Amp Draw: 3.0AMP.It doesn't mean 4L/min jet at 80 PSI. - The balanced motor design incorporates precision ball bearings for long life, motor is equipped with an integral thermal breaker.WARNINGS: DC 12V Power supply ONLY!! No AC power. Voltage OVER 14V can burn the motor. - All marine duty pumps have sealed switches and are finished with a Electro Coating to inhibit corrosion. This is NOT a submersible pump. Caution: Not for use in wet/damp areas – motor is not sealed. Do NOT submerge it in water. - The soft rubber mounting feet provide good cushion from vibration. When installed correctly, marine duty fresh water pumps provide years of quiet operation. - The pump in combination with a low backpressure water system can exceed all expectations. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N75ZIXF | | Best Sellers Rank | #18,517 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #8 in Diaphragm Pumps | | Brand Name | bayite | | Color | Black | | Customer Reviews | 4.3 4.3 out of 5 stars (2,603) | | Flow Rate | 4 Liters Per Minute | | Included Components | 12V DC Diaphgram Pump Body X 1, Hose Clamps X 2, User Manual X 1 | | Item Dimensions L x W x H | 6"L x 4"W x 2.2"H | | Item Weight | 1.5 Pounds | | Manufacturer | bayite | | Manufacturer Part Number | BYT-7A102 | | Manufacturer Warranty Description | 1 Year Warranty | | Material Type | Plastic | | Maximum Lifting Height | 5 Feet | | Model Number | BYT-7A102 | | Power Source | DC Power Supply | | Product Style | 12v sprayer pump | | Voltage | 12 Volts | ## Product Details - **Brand:** bayite - **Color:** Black - **Item Weight:** 1.5 Pounds - **Material:** Plastic - **Maximum Flow Rate:** 4 Liters Per Minute - **Maximum Lifting Height:** 5 Feet - **Power Source:** DC Power Supply - **Product Dimensions:** 6"L x 4"W x 2.2"H - **Style:** 12v sprayer pump - **Voltage:** 12 Volts ## Images ![12V DC Fresh Water Pressure Diaphragm Pump with Hose Clamps Self Priming Sprayer Pump with Pressure Switch 4 L/Min 1.0 GPM 80 PSI for RV Camper Marine Boat - Image 1](https://m.media-amazon.com/images/I/6195o68UJfL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Totally satisfied - hard working small pump *by M***L on August 17, 2025* I am seriously impressed with this.

It is tiny, but seemed up to the task. The only complaint is that the pressure switch surges off and on repeatedly unless the flow rate through the pump is great enough to make the pump happy. I kept adding emitters until the pump worked as desired. ## Frequently Bought Together - bayite 12V DC Fresh Water Pressure Diaphragm Pump with Hose Clamps Self Priming Sprayer Pump with Pressure Switch 4 L/Min 1.0 GPM 80 PSI for RV Camper Marine Boat - 3/8" ID x 10 Ft High Pressure Braided Clear PVC Vinyl Tubing Flexible Vinyl Tube, Heavy Duty Reinforced Vinyl Hose Tubing, BPA Free and Non Toxic - Water Pump Strainer, 3/8 Inch Hose Barb In-Line Strainer Twist-On Sprayer Filter for Water Pump 12V DC 80 PSI RV Camper Marine Boat Lawn --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/40803966-12v-dc-fresh-water-pressure-diaphragm-pump-with-hose-clamps](https://www.desertcart.us/products/40803966-12v-dc-fresh-water-pressure-diaphragm-pump-with-hose-clamps) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
