Abstract
Device and method for protecting a submersible pump. The device can include a housing for connecting to a downhole pump, and a plurality of shelves disposed throughout the housing, wherein at least two shelves are axially spaced from one another, and each shelf provides a surface for supporting and collecting sand or other solids within the housing. A restrictor assembly can be disposed at one end of the housing and configured to allow fluid flow through the housing in one direction and at least partially restrict flow through the housing in an opposite, second direction.
