Lasting quality with SPX FLOW Johnson Pump brand impellers For the well-being of your boat engine your water-cooling pump must be able to supply a minimum specified continuous flow of cooling water. The flexible impeller in your pump, which provides this pumping action, is a wear part. Over time the impeller will lose its ability to maintain the pressure needed for the flow of cooling water and must be replaced. A good quality impeller will provide you with many months of problem-free operation. For an impeller of lesser quality, the performance can degrade so rapidly that you, at best, must replace the impeller more often; at worst, you could be left adrift with engine damage. SPX FLOW engineers Johnson Pump impellers for outstanding performance!
What makes Johnson Pump the original and replacement impeller of choice? PERFORMANCE Stable pressure delivery over time - Ensures correct cooling flow.
- Significantly longer service life…in some applications up to 4x longer than the competition (at a given duty cycle).
Excellent self-priming capability - Ensures sufficient cooling directly at start up.
Correct impeller dimensions - Our impellers are manufactured to strict tolerances for optimal functionality unique MC97 rubber compound.
- Ensures flexibility for self-priming capabilities and minimizes failure due to fatigue (broken blades). Provides stronger bonding to avoid hub slip.
DEVELOPMENTAL KNOW-HOW With its Johnson Pump brand SPX FLOW 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.
