cykleking 12V DC RV Water Pump 3.5 GPM 45 PSI, Orange-1 compact self-priming diaphragm pump with pressure switch

cykleking 12V DC diaphragm water pump delivers up to 3.5 GPM and a factory-set 45 PSI shut-off for dependable on-demand water in RVs, boats, and off-grid setups.

This compact, portable pump runs on 12-volt DC power and is engineered for mobile living: it self-primes, includes thermal and overload protection, and mounts on vibration-damping rubber feet for quieter operation. Lightweight and corrosion-resistant, it supports showers, sinks, deck washdowns, garden irrigation, and rain-barrel gravity boost—making it a flexible water mover for campers, marine craft, and remote cabins.

How does the pump supply steady water pressure for showers and sinks?

The pump uses a built-in pressure switch calibrated to shut off at 45 PSI by default and can be adjusted within roughly 40–80 PSI to suit fixtures. When a tap opens, the pump automatically restarts to maintain consistent flow and pressure, giving near-constant performance for plumbing fixtures without manual intervention.

• Factory shut-off pressure: 45 PSI (adjustable)
• Flow capability: up to 3.5 gallons per minute (GPM)
• Automatic on-demand start/stop via integrated pressure switch
• Smooth cycling minimizes pressure spikes for delicate fixtures

What makes this pump suitable for off-grid or marine use?

Powered by a standard 12V DC source, the pump runs from batteries, solar systems, or vehicle power, so it’s ready for boondocking, boating, and remote installations. Its lightweight build (about 4.88 lbs) and included inlet filter and hose connectors simplify installation, while self-priming capability and rust-resistant components extend usable life in damp environments.

• 12-volt DC operation for battery or solar setups
• Self-priming up to 9.8 ft for easy suction from tanks
• Included 50-mesh inlet strainer and two barb fittings
• Compact, portable design ideal for tight boat and RV compartments

How quiet and durable is the pump during regular use?

Noise and vibration are reduced through an engineered rubber mounting base that isolates the unit from chassis and bulkhead resonance. Thermal and overload protection guard the motor against overheating and electrical stress, increasing reliability for repeated daily cycles like showers and dishwashing on a trip.

• Rubber mounting base for vibration damping and quieter operation
• Built-in thermal and overload protection for motor safety
• Diaphragm design resists cavitation and dry-run damage better than some pumps
• Corrosion-resistant housing suited for marine exposure

What accessories and parts are included for installation?

The pump ships with a practical hardware kit that covers common DIY installations so you can get running quickly without sourcing extra items. The kit includes fittings, a strainer to protect the diaphragm, and basic tools to seal and secure hose connections.

• 1 × diaphragm water pump (12V DC)
• 2 × barb hose connectors and 1 × 50-mesh inlet strainer
• 1 × L-shaped wrench and 1 × roll of PTFE (Teflon) tape
• User manual with wiring and mounting recommendations

Who is this for? The cykleking 12V RV water pump is aimed at RV owners, boaters, van-lifers, gardeners using rain barrels, and anyone needing a portable, battery-powered water solution. Choose it if you want a lightweight, self-priming diaphragm pump with adjustable pressure, quiet mounting, and out-of-the-box install accessories for reliable water delivery on the road or off-grid.
