Viking Pump's Lid-Ease® strainers are specially designed to protect any pumping system by preventing solids or foreign materials from entering the pump. The Lid-Ease strainers ensure reliable performance and maximum pump uptime. For example, high differential pressures are accommodated by a perforated stainless steel basket with maximum hoop strength, which supports an inner stainless steel screen. Differential pressure indicators that show when the basket needs to be cleaned are optional. To stop entrained solids and foreign materials, the strainer basket comes in numerous options, from 10 to 100 mesh screens, or no screen (basket openings 0.188" dia.). The basket can include optional magnetic inserts for trapping ferrous particles. Also, maintenance is made trouble-free by a breech lock lid that enables simple top removal of the basket for cleaning. Viking Pump.
