April 27, 2026

When it comes to marine maintenance, protecting your engine and onboard systems from debris is non-negotiable. The JPR-ST2010 JMP Marine Seawater Strainer is engineered to deliver reliable filtration, durability, and ease of maintenance—making it a smart investment for boat owners who value performance and longevity.

Why a Seawater Strainer Matters

Seawater strainers play a critical role in preventing harmful debris, sand, and marine growth from entering your cooling system. Without proper filtration, these contaminants can clog pumps, reduce efficiency, and even lead to costly engine damage. The JPR-ST2010 is designed to act as a first line of defense, ensuring clean water flow and optimal engine performance.

Built for Durability and Performance

One of the standout features of the JPR-ST2010 is its robust bronze construction. Both the top and bottom castings are made from high-quality bronze, offering exceptional resistance to corrosion in harsh marine environments. This durability ensures long-term reliability, even in saltwater conditions.

Inside, the stainless steel filter basket (with a 3mm filtration size) efficiently captures debris while maintaining strong flow rates. The included transparent cylinder (130mm diameter x 100mm height) allows for quick visual inspection, so you can easily monitor buildup without disassembly.

Optimized Flow and Efficiency

Performance is where this strainer truly shines. With a 1” BSP inlet and outlet, the JPR-ST2010 supports consistent water flow across a range of engine speeds. At 2000 RPM, it can achieve flow rates up to 122 liters per minute at 0 bar, ensuring your cooling system operates efficiently under demanding conditions.

Even under increased pressure, the unit maintains strong flow performance, making it suitable for a variety of marine applications—from leisure boats to more demanding commercial setups.

Designed for Easy Maintenance

Marine maintenance can be time-consuming, but this strainer simplifies the process. Key features include:

  • Wingnut-secured lid for quick access
  • O-ring sealing system for reliable, leak-free performance under pressure
  • Center rods and air cap for straightforward disassembly
  • Replaceable components like the FIL0008 filter basket and ZEN000101 anode

Routine cleaning and part replacement can be done quickly, minimizing downtime and keeping your vessel running smoothly.

Compact Yet Powerful Design

Despite its rugged build, the JPR-ST2010 remains compact, measuring 150mm x 220mm x 180mm and weighing approximately 6.15 kg (13.5 lbs). This makes it easy to install in tight engine compartments without sacrificing performance.

Key Benefits at a Glance

  • Protects engines and pumps from debris damage
  • High-strength bronze construction for marine durability
  • Transparent housing for easy inspection
  • Efficient stainless steel filtration system
  • Simple installation and maintenance design

For boat owners looking to improve engine reliability and reduce maintenance headaches, the JMP Marine ST Series Seawater Strainer (JPR-ST2010) is a dependable solution.
