* The standard booster has the greatest flow, and should be used where suction lift is less than 10 feet. 
** Conversely, The low flow model should be used where suction lift is greater than 10 feet or where the suction pipe is less than 1“ in diameter;  it has a higher pressure capacity. Maximum suction lift is 20 feet (at sea level).
