Water Pressure Pump WPS 4.0 12V by Advance Trident

The WPS 4.0 12V from Advance Trident is a compact, high‑performance heart for pressurized water systems in boats, RVs, off‑grid cabins, and mobile wash setups. Designed to deliver reliable on‑demand water, this 12V pump blends power, efficiency, and quiet operation in a small footprint, making it easy to keep showers, sinks, and spray zones flowing smoothly wherever you go.

Why it stands out

At the core is a five‑chamber diaphragm design that delivers a smooth, pulsation‑free flow even when you’re running taps at low speeds. Paired with a dedicated heavy‑duty sealed pressure switch, the WPS 4.0 maintains steady pressure while minimizing water hammer and noise. A safety cut‑out at 2.8 bar (41 psi) guards your fixtures and helps you avoid pressure spikes, giving you dependable performance without guesswork.

Key benefits and features

• Strong yet efficient 12V operation — up to 15 L/min (4.0 GPM) with a compact 100W motor for versatile, quiet water delivery.
• Reliable, low‑maintenance design — five‑chamber diaphragm and sealed components minimize wear and reduce maintenance needs.
• Consistent pressure — dedicated pressure switch keeps output steady and reduces water hammer across multiple outlets.
• Multiple outlets from one pump — feed up to five taps or devices without juggling separate pumps.
• Easy hookup — quick‑connect ports sized for 1/2" or 3/4" hoses streamline installation in boats, campers, and utility cabinets.
• Debris protection — 40‑mesh inlet strainer guards against debris to minimize clogging in outdoor or marina environments.
• Quiet operation — diaphragm design and sealed components keep noise to a minimum for a peaceful space.

Ideal applications

Whether you’re outfitting a compact sailboat, a camper van, or a mobile wash station, the WPS 4.0 12V delivers steady pressurized water on demand. It’s perfect for powering showers, sinks, spray nozzles, and wash‑downs—great for daily chores like rinsing gear, washing down decks, or refreshing a compact living space without constant priming or pressure fluctuations.

How it works in your system

Installation is straightforward thanks to universal quick‑connect ports for 1/2" or 3/4" hoses. The unit draws from a 12V DC source, protected by a 10A fuse for simple electrical safety. The 40‑mesh inlet screen keeps debris out of the pump, helping maintain steady flow in lakeside marinas, dusty campsites, or rocky shorelines. With a safe cut‑out at 41 psi, you protect fixtures and maintain reliable performance across daily use scenarios.

Practical tips for best results

• Place the pump close to the water source and near a fused 12V power supply to minimize wiring losses.
• Use the 1/2" or 3/4" hose fittings to match your existing plumbing layout for a clean, secure connection.
• Keep the 40‑mesh inlet strainer clean to preserve flow and reduce the chance of clogging in outdoor environments.
• Plan for up to five outlets in your layout to enjoy simultaneous taps without noticeable pressure drops.
