Expert opinion

« Technical analysis: Shurflo ProBlaster II Ultimate 5.0 12V deck wash pump »

The Shurflo ProBlaster II Ultimate 5.0 12V pump is a deck wash solution designed for demanding marine applications. With a flow rate of 18.9 litres per minute (5.0 GPM) at 0 bar and a cut-off pressure of 4.1 bar (60 PSI), it delivers substantial cleaning capacity for rinsing decks, anchor chains, or fishing gear on mid-sized to large pleasure boats and small professional craft.

A key advantage of this model is its dry priming capability up to 1.82 metres (6 feet), providing flexibility in installation location and allowing it to be positioned above the water source level. Additionally, the pump can run dry without damage, a critical factor for reliability at sea where water supply may be intermittent. Thermal overload protection with automatic restart also contributes to motor durability under varied operating conditions.

In terms of integration, 12V power is standard for most onboard systems, and a 20-amp fuse is recommended to secure the circuit. The ½"-14 NPSM-Male ports come with swivel adapters for ¾" barb or NHR Male ¾" connections, facilitating integration with common piping. It is essential to respect the maximum inlet pressure of 2.06 bar (30 PSI) and the maximum liquid temperature of 54°C (130°F), which makes it suitable primarily for cold or ambient water and suction from a tank or the sea. Materials such as EPDM for valves/seals, Santoprene for the diaphragm, and stainless steel for fasteners ensure good resistance to corrosion inherent in the marine environment. This ProBlaster II Ultimate 5.0 model positions itself as a robust and high-performance choice for users seeking a reliable and powerful deck wash system.
