Shurflo AQUA KING II Junior Fresh Water Pump - 12 VDC, 2.0 GPM - 4128-110-E04

Key Performance Features

The Junior model focuses on efficiency and quiet operation for modest water needs.

• Smooth Flow Technology: Equipped with a 3-chamber diaphragm and internal bypass, this pump reduces rapid cycling. This allows for a more consistent flow at low demand without the need for an external accumulator tank.

• Dry-Run Capability: Engineered to run dry without damage, protecting the internal components if your freshwater tank accidentally runs empty.

• Corrosion Resistance: The motor is protected by a seamless e-coated shell and features sealed end bells to prevent moisture from entering the motor housing, which is critical for marine longevity.

• Quiet Operation: Designed with noise-reducing rubber feet and a balanced motor to minimize vibration and sound during use.
