Rating: 5 (1 reviews)

5.5 GPM | 60 PSI | 12V DC | Integrated 1L Accumulator Tank

The SEAFLO WSK1055060003 is a fully integrated, pre-assembled water pressure system designed to provide smooth, consistent water flow for yachts, RVs, and off-grid applications. By combining the heavy-duty 51-Series 5-chamber diaphragm pump with a 1.0-litre accumulator tank, this system eliminates pump cycling and water pulsation, resulting in a quieter operation and extended motor life.

PRECISION PERFORMANCE: Features an adjustable pressure switch and a large 5-chamber diaphragm for high-volume delivery across up to 5 fixtures simultaneously.

Key Features

✔ Pre-Assembled Design: Mounted on a durable board for fast installation.
✔ Reduced Cycling: 1L tank prevents rapid pump start/stops.
✔ Dry-Run Safe: Can run dry without damaging the pump head.
✔ Self-Priming: Suction lift up to 6 feet (1.8m).
✔ Ignition Protected: Meets ISO 8846 standards.

Questions & Answers

Is this a genuine original part?

This is a genuine SEAFLO professional-grade water system kit, manufactured to meet or exceed marine ignition protection standards (ISO 8846).

How do I know if it is compatible?

We recommend checking the SKU/MPN (WSK1055060003) against your existing setup. This kit is a universal high-flow solution for 12V systems requiring 5.5 GPM output.

Why is the 1L accumulator tank important?

The accumulator tank acts as a pressure buffer. It allows the system to provide small amounts of water without the pump needing to switch on every time a tap is opened slightly, significantly reducing noise and wear on the motor.

Note: Professional installation is recommended. Ensure the tank pre-charge is set correctly (approx. 2 PSI below pump cut-in pressure) for optimal performance. Visit 4boats.co.uk for more marine components.
