Poolaroo Pro Tip

Before ordering, match your pump's model number to the Fits Into table. Pay particular attention if you have an IntelliFlo i1 or i2 (fitment is noted as after April 2016) or an IntelliFloXF (VS model only). Compare this drive to your existing drive before ordering. Drive replacement is best handled by a qualified pool professional.
