Introduction
A self-cleaning strainer is a device installed in a pipe-
line to remove dirt and other unwanted debris from
fluids. Straining is accomplished by directing the fluid
through "sized" openings in perforated straining ele-
ments. Self-cleaning strainers have integral back-
wash systems designed to isolate and clean a small
portion of the element while the remaining area contin-
ues to strain normally. During operation, fluid flow
through the strainer is continuous. A small quantity of
"clean" fluid is used to wash the element and then
carry the concentrated debris away from the strainer
through the backwash system.

Questions and answers
we have a small amount of oil leaking from the exposed shaft what are the required parts to reseal the end of the shaft
To reseal the exposed shaft on an Eaton 2596 with a small oil leak, the following parts are needed:
- Quad-Rings (C) (1 piece)
- O-Ring (1 piece)
- Gland Gasket (F) (1 piece)
These components help seal the shaft and prevent oil leakage. Additionally, a Process Compatible Lubricant should be used to lubricate the Quad-Rings during installation.
