High Flow Rate
Delivers up to 3.0 gallons per minute, equivalent to approximately 11.36 liters per minute.

Upgrade your mobile water system with a powerful 12V diaphragm pump engineered to deliver consistent pressure. Its 4-chamber design provides a high flow rate for showers, sinks, marine systems, campers and other demanding water applications.
Delivers up to 3.0 gallons per minute, equivalent to approximately 11.36 liters per minute.
Provides dependable water pressure to help reduce weak showers and slow-filling sinks.
The 4-chamber diaphragm design supports a strong, consistent flow across a variety of applications.
Designed for common 12V systems used in RVs, campers, boats and mobile service vehicles.

The powerful 4-chamber diaphragm core delivers 3.0 GPM at a steady 55 PSI. Whether you are taking a shower, filling a sink or supplying water to onboard fixtures, the pump helps maintain dependable flow.
Moves up to 11.36 liters of water per minute for efficient everyday operation.
Maintains steady pressure for more comfortable showers and faster water delivery.
Promotes smooth water movement and dependable performance across multiple fixtures.
The integrated pressure switch automatically starts the pump when a faucet is opened and stops it when the faucet is closed. Adjust the pressure setting to match the needs of your water system.
A drop in line pressure activates the pump automatically, without requiring a separate manual switch.
The 4-chamber pump supplies consistent water pressure for your connected fixture or appliance.
The pump shuts off automatically when demand stops, helping simplify everyday operation.
A pure copper motor, lightweight pump body and noise-reducing mounting base work together to reduce vibration and operating noise. It is a practical choice for enclosed RV, camper and marine installations.
Designed to support efficient, stable performance during everyday water-system operation.
The mounting base helps isolate pump movement and reduce vibration transferred to the installation surface.
Helps make the pump suitable for use in living, sleeping and working environments.
Integrated protection features help safeguard the pump during demanding use and unexpected water-system conditions.
Helps protect internal components if the motor temperature rises beyond the intended operating range.
Provides an additional layer of protection against excessive electrical demand.
Designed to tolerate temporary dry-running conditions when the incoming water supply is interrupted.
The bypass design helps maintain a path for water flow if the pump or valve becomes unavailable.

The compact 12V design makes this diaphragm pump a versatile solution for recreational vehicles, marine systems, mobile businesses and outdoor water-transfer tasks.
