Danfoss 180B3045 APP 2.2 Piston High‑Pressure Seawater Pump is a robust, high-performance pump engineered for demanding maritime and offshore applications. With its precision piston mechanism and part number 180B3045 clearly identified in the description, this pump delivers exceptional pressure handling and reliable operation in corrosive seawater environments. Designed to meet the stringent requirements of shipboard systems, ballast control, fire suppression, and desalination processes, the APP 2.2 model combines high pressure capability with seawater compatibility for rugged marine performance.
At the core of the APP 2.2 pump is a multi-piston arrangement that ensures smooth, pulsation-minimized flow even under variable load conditions. Built from corrosion-resistant materials such as marine-grade stainless steel and high-performance seals, this pump resists the erosive effects of saltwater and maintains long-term operational integrity. The 2.2 designation reflects its continuous high-pressure capability, enabling safe and efficient delivery in systems that require bar-level pressure stability—ideal for high-demand seawater handling duties.
Precision-engineered internals, including hydraulically balanced pistons and PTFE-based dynamic seals, provide excellent volumetric efficiency with reduced internal leakage. This results in lower energy consumption and higher output pressure despite challenging operating conditions. Its compact footprint and modular hydraulic drive allow seamless integration into pump skids, marine manifolds, or independent installations aboard vessels where space optimization and performance reliability are essential.
Maintenance and serviceability are key strengths of the Danfoss 180B3045 APP 2.2. Service-friendly design features include easy-to-access piston housings, replaceable seal cartridges, and standardized port connections for rapid replacement and integration. The pump’s proven reliability, combined with Danfoss’s engineering excellence, offers vessel operators confidence in uninterrupted performance, minimal downtime, and reduced life-cycle costs. Overall, this high-pressure seawater piston pump delivers precision, corrosion resistance, and durability—making it an indispensable component for modern marine and offshore systems.
