7. hose should be kept as short as possible for more efficient operation Operation Concerns 1 Cavitation This is the sudden formation and collapse of low pressure vapor bubbles across the vanes of the impeller Cause When the surface pressure on a liquid becomes low enough the liquid will begin to boil even at room temperature With centrifugal pumps cavitation can occur when the suction vacuum becomes too great allowing water vapor or bubbles to form at the impeller The rapid pressure increase can cause impeller damage Solution Minimizing suction head and using the largest practical suction hose diameter will reduce the likelihood of cavitation Do not use a suction hose with a diameter smaller than the Pump s Intake Port 1 5 diameter 2 Water Hammer Pressure This is energy sent back to the Pump due to sudden stoppage of water flowing from the Pump Cause Water hammer pressure is more likely to occur when using a very long discharge hose If the flow of water at the end of the discharge hose is shut off suddenly energy is sent back to the pump This causes a large pressure spike in the Pump housing leading to potential damage to the Pump casing Solution Use as short a discharge hose as possible and turn off water pump before closing water flow Page 7 For Engine technical questions please call 1 800 520 0882 Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual in
