Description
The SHURflo Aqua King II is a 12V automatic freshwater pressure pump for marine and coastal RV applications. It supplies taps and showers on demand, starting as system pressure drops and stopping when pressure is restored. Reliable and quiet, it can run dry without damage, but is designed for intermittent use rather than continuous pumping.
The 11.4 L/min rating is free flow, not delivery at 55 psi: flow decreases as pressure rises, and 55 psi is the pressure-switch cut-off.
Install a 50-mesh inlet strainer and flexible high-pressure hose on both ports. Direct connection to rigid plumbing can transmit vibration and loosen or crack components. Mount the pump on a solid surface in a dry, ventilated, accessible location. The attached manual covers installation, maintenance and troubleshooting.
Features
- It automatically senses when the tap has been switched on.
- Ideal for coastal RV applications or marine applications.
- Internal bypass helps maintain smooth flow and reduce rapid cycling at low demand; an accumulator is not required.
- Sealed motor and switch, with a corrosion-resistant motor coating.
- Thermal overload protection with automatic restart.
- 1 year warranty.
