The Seaflow 12V 22 Series 1.3GPM water pump is a compact automatic demand diaphragm pump suited to small pressurised water systems, liquid transfer, spraying, circulation, filtration and dispensing applications.
This unit is the 12V 22 Series version with a 1.3GPM / 5.0LPM open flow rate and 100PSI / 6.9BAR shut-off pressure. It is a practical option for caravans, RVs, boats, service vehicles, camper builds, small water treatment systems and general 12V transfer or pressurisation setups.
The pump has a built-in pressure switch, allowing it to automatically start when an outlet is opened and stop when the outlet is closed. Internal bypass technology helps reduce cycling, while the self-priming diaphragm design allows the pump to be mounted above the water source when installed correctly.

Installation Notes
- Designed for 12V DC electrical systems only.
- Use suitable wiring, fuse protection and correct polarity when installing.
- The pump should be mounted securely using the rubber mounting feet.
- Use compatible 3/8" / 10mm hose connections.
- A filter or strainer should be used before the pump where debris may be present in the water supply.
- Final suitability depends on the water source, plumbing layout, number of outlets, wiring setup and intended use.
Important: This is a compact 12V 1.3GPM pressure pump, not a high-flow washdown pump. Confirm voltage, flow rate, pressure requirements, hose size, mounting space and intended application before ordering.
