ECO-WORTHY 33-Series 110V AC Diaphragm Water Pump, 4.0 GPM, 50 PSI
Product description
For an RV sink, boat faucet, or outdoor water setup, the ECO-WORTHY 33-Series diaphragm pump is designed to deliver pressurized water from a 110V AC power source. It offers 4.0 GPM open flow and self-priming up to 9.8 feet. An automatic pressure switch starts and stops the pump as you operate a faucet. That makes it a practical choice for water systems where faucet-controlled operation matters.
Practical tips
Use this pump in applications such as an RV or camper water system, a boat or marine setup, irrigation, sprinklers, or courtyard water transfer. Its self-priming capability reaches up to 9.8 feet, a useful detail when planning the pump’s position relative to the water source. The unit is corded electric and operates on 110V AC, so plan for a suitable power connection at the installation point. Its stated dimensions are 9.45 inches long, 5.31 inches wide, and 5.12 inches high, which can help when considering available mounting or storage space.
Strengths
The automatic pressure switch is designed to start the pump when a faucet is turned on and stop it when the faucet is turned off. This gives a water system a straightforward, faucet-led operating routine instead of requiring a separate manual start and stop for each use. The rated pressure is 50 PSI, and the adjustable pressure range is 45–70 PSI, allowing the pressure setting to be adjusted to suit the application. Need a pump that responds to faucet use? This automatic control is a practical feature for RV kitchens, camper bathrooms, and marine water systems.
The 4.0 GPM open flow rate supports water delivery for everyday faucet use and other listed applications, including irrigation and sprinklers. For setups that involve a vertical lift, the pump is specified for self-priming up to 9.8 feet and lifting up to 148 feet. These figures describe different stated capabilities, useful when assessing the layout and water route for a project. Built-in thermal overload protection disconnects the circuit if the temperature rises above 158°F, protecting the motor as part of the pump’s operation. The pump is also rated for continuous operation for more than one hour.
