The No-Vault pump filter from Sim/Tech Filter is designed to help protect turbine pump intake screens. Filtration is achieved through a choice of a 6-inch diameter PVC or 316L stainless steel screen with 1/16-inch diameter perforations. The shorter model has 139 square inches of open area, while the tallest model has 325 square inches of open area. With 35 to 80 times the open area of the intake screen, it helps reduce the frequency of screen and pump cleaning. The interior sealing sleeve allows it to adjust to different pipe heights. The smallest unit handles pumps up to 26 inches tall, while the largest unit handles pumps up to 50 inches tall. The simple unit is easily installed in new systems or retrofitted onto existing systems. 888-999-3290; www.simtechfilter.com.
