cykleking 12V High-Pressure Diaphragm Water Pump, Orange-2, 5.5 GPM 70 PSI with Smart Pressure Switch

cykleking's 12V high-pressure diaphragm pump delivers on-demand freshwater at up to 5.5 GPM and 70 PSI for RVs, boats, campers, and off-grid washdown systems.

This compact 12-volt DC pump combines a self-priming diaphragm design with a smart pressure switch so it starts and stops automatically when a faucet or sprayer is opened and closed. Built for mobile and remote use, it balances strong flow with manageable current draw and straightforward plumbing and electrical connections. The pump works well for freshwater delivery, deck washdowns, portable showers, and small irrigation or sprayer setups where a reliable, pressurized water supply is needed.

How much flow and pressure can I expect from this pump?

The cykleking pump provides up to 5.5 gallons per minute (GPM) and a maximum pressure of 70 PSI, suitable for typical RV and marine freshwater systems. Flow and pressure vary with head height and plumbing restrictions, so expect lower flow at higher vertical lifts.

• Rated flow: 5.5 GPM under optimal conditions
• Maximum pressure: 70 PSI for steady spray and fixtures
• Self-priming lift: up to 9.8 feet vertical
• Maximum vertical head: 131 feet theoretical limit

Will the pump run automatically with my fixtures?

Yes — the built-in smart pressure switch provides on-demand operation so the pump starts when you open a faucet and stops when you close it. That removes the need for a separate external controller and keeps system plumbing simple.

• On-demand pressure switch for automatic start/stop
• Maintains system pressure without manual relays
• Smooth cycling suited to typical RV and marine fittings
• Works with handheld showers, faucets, and spray nozzles

What electrical and installation details should I know?

The pump runs on 12 V DC and draws about 5 A under normal load with a maximum surge up to 12.5 A. It’s compact and mounts easily in engine bays, compartments, or under sinks; follow basic wiring and fuse protection best practices during installation.

• Supply voltage: 12 V DC — suitable for vehicle and marine battery systems
• Typical current: 5 A; max draw up to 12.5 A during startup
• Provide a fused power feed and secure ground for safety
• Include flexible hoses and proper hose clamps on inlet/outlet ports

How do I keep the pump reliable over time?

Routine checks and simple maintenance help extend diaphragm pump life. Inspect hoses and fittings for leaks, protect the pump from freezing, and flush the system if water sits for long periods.

• Inspect and tighten hose clamps periodically
• Protect from freezing — drain system in cold storage
• Use clean freshwater; filter or strain if debris is present
• Replace diaphragm or check valves as wear items if performance drops

Who is this pump for? If you need a compact, on-demand freshwater pump for an RV, camper, boat, off-grid washdown, or portable sprayer, the cykleking 12V diaphragm pump is designed for that role. It suits DIY installers and professional fitters who want a self-priming unit with a smart pressure switch, solid flow for everyday tasks, and straightforward electrical and plumbing connections. Choose this pump if you require reliable pressurized water without complex controllers, and match installation components — wiring gauge, fuse size, hose diameter — to your vehicle or vessel’s specifications for best results.
