SD47034 Pump Saver 16 oz | Winterizing & Storage Protectant

SD47034 Pump Saver 16 oz | Winterizing & Storage Protectant

The AR SD47034 Pump Saver 16 oz is a high-performance maintenance solution developed by Annovi Reverberi to provide comprehensive protection for pressure washer pumps, seals, and internal components during long-term storage or seasonal inactivity. Formulated for both professional and residential use, this premium preservation fluid prevents corrosion, mineral buildup, and freeze-related damage, ensuring that pressure washer pumps remain in peak operating condition when returned to service. The 16-ounce bottle contains a concentrated formula that delivers complete internal coverage using minimal product, making it ideal for multiple applications depending on pump size.

The AR SD47034 works by displacing any residual water left in the pump and coating all internal surfaces—including seals, pistons, valves, and connecting passages—with a thin lubricating film that creates a protective barrier against oxidation, rust, and mineral crystallization. This film helps preserve the pump’s internal metal components while maintaining the elasticity and sealing properties of rubber and elastomer parts.

Designed with anti-freeze properties, it provides reliable freeze protection for pumps stored in cold environments by preventing trapped water from expanding into ice that could otherwise crack brass manifolds, damage ceramic plungers, or compromise seals. In addition to preventing freezing, the formula significantly reduces startup friction by lubricating seals and pistons, preventing the sticking, cracking, or tearing that commonly occurs when pumps sit idle for extended periods.

The SD47034 Pump Saver is compatible with all AR North America pumps and most major pressure washer brands that feature similar water-seal designs, making it a versatile and universal maintenance fluid. It is safe for use on brass, stainless steel, ceramic, and plastic components and will not degrade elastomer seals or affect internal tolerances. Its formulation preserves O-ring and packing flexibility, ensuring consistent hydraulic sealing and preventing dry start damage when the unit is brought back into operation.

How to Use the AR SD47034 Pump Saver

Simple, Mess-Free Application

Applying the Pump Saver is quick and easy. Users simply connect the bottle directly to the pump’s water inlet or detergent injection port and run the pump briefly to circulate the fluid until it exits the outlet. Once the fluid has cycled through, all internal components are fully coated and ready for safe storage.

• No additional tools required
• Direct-connect design for convenience
• Treatment lasts for months
• No draining or cleaning needed before restarting the pump

When the pump is restarted, the lubricating film dissipates naturally, allowing the system to operate normally without any extra steps.
