What Makes Johnson Pump the Original and Replacement Impeller of Choice?

With SPX Johnson pump you get:

• Performance Stable Pressure delivery over time
  • Ensures the correct cooling flow
  • Significantly longer service life – in some applications up to 4 times longer than the competition (at a given duty cycle).
• Excellent Self-priming capability
  • Ensures sufficient cooling directly at startup
• Correct impeller Dimensions
  • Manufactured to strict tolerances for optimal functionality
• Unique mc97 rubber compound
  • Ensures flexibility for self-priming capabilities and minimises failure due to fatigue (broken blades)
  • Provides stronger bonding to avoid hub slip

Developmental know-how with its Johnson pump brand SPX is an original manufacturer of world class impellers for more than 40 years:

• More than 125 years of accumulated engineering time
• Documented, standardized testing
• Continuous quality testing, annually 150,000 test hours
• In excess of 150,000 hours testing of our mc97 rubber compound

Marine Compound 97 (rubber compound mc97)

One of our secrets for success is our rubber compound mc97; optimized to provide maximum life, especially for applications where the end user doesn’t run the engine on a regular basis:

• Stable pressure delivery over time
• Minimized failures due to fatigue
• Minimized swelling

Always use Johnson Pump original impeller lubricant since many rubber compounds are sensitive to petroleum products.

Most SPX Johnson Impellers come with gaskets and lubricant.

Boat Hut Insight

When choosing an impeller, consider how often you realistically run your engine. If you’re the kind of boatie who only fires up the engine on weekends or holidays, the mc97 compound’s fatigue resistance and minimal swelling are absolute lifesavers. Also, keep a spare impeller aboard – they’re the unsung heroes of your cooling system, and a broken blade can turn a perfect day on the water into a very long wait for a tow. And a quick tip: always lubricate the impeller with the recommended Johnson Pump lubricant to avoid premature wear – it’s a small step that saves a lot of hassle!
