Eductor Jet Venturi Nozzles for Returns and Flow Assistance Size:1/4" Since these pumps are notEductor jets use a venturi design which enables smaller pump flows to circulate larger volumes of water. Eductors will circulate 4 to 5 gallons of water for each gallon pumped (So 500gph of pumping translates to 2000gph of total circulation). This principle makes educator jets an excellent choice for pond returns & assist in "sweeping" debris to bottom drains & filters or fixing stagnant areas. These educators are also effective for use as decorative
