Reduce motor speed (RPMs). Note: Slowing the pump down will reduce flow rate and head pressure. Install an impeller inducer Incorporate a booster pump into your pump system. This will take some of the stress off of your primary pump. If possible, reduce the temperature of your pump, liquid, and/or other components. Increase liquid level around the suction area. If possible, try to increase the diameter of the eye at the centre of your impeller.
