THE PONDMASTER X-SERIES is designed for moderate to high volume pumping for both ponds and waterfalls. Despite their greater pumping capacity, these heavy-duty 115V pumps are extremely energy efficient, using less power than other comparable direct drive and magnetically driven pumps. Available in 5 models in either single speed or two speed configurations, they offer pumping capacities from 2500 GPH to 8400 GPH. All X-Series pumps come standard with 6' power cords, back flow check valves, and 6" debris-limiting filter baskets. They are adaptable to standard 1-1/2" to 2" PVC pipe fittings.
