Whats the difference between a regular model and a dual drive model?
For applications with insufficient pressure to operate the strainers, Sure-Flo created the dual drive series. Identical to the regular strainer with an additional set of cleaning nozzles located 180 degrees from the primary nozzles. Although these strainers require more gallons of cleaning water, they can operate at lower pressures. Since the screen is cleaned twice per revolution, the dual drive models have become popular for applications in very heavy debris sources, even when higher pressure is available.
