Rule Marine Pumps are designed for marine applications with key specifications including sizes ranging from 500 GPH to 4000 GPH. They are graded for both freshwater and saltwater use. The pumps handle fluids with low to medium viscosity, typically under 1000 cP. Buoyancy is not a primary feature as they are submersible or inline pumps. Materials include corrosion-resistant thermoplastic, stainless steel, and rubber components for durability in harsh marine environments.
Marine Pumps (generic marine pumps) vary by model but commonly feature sizes from 12V to 24V DC operation, with flow rates between 300 GPH and 5000 GPH. They are graded for marine and industrial use, handling fluids with viscosities up to 1500 cP. Buoyancy depends on the design, with some models being float-switch activated. Construction materials often include polypropylene, bronze, or cast iron for corrosion resistance and longevity in seawater applications.
