  Features

Keckley duplex continuous flow basket strainers are used in continuous flow applications where the process cannot be shut down for cleaning. Some examples are lubrication systems, industrial or marine oil burners, chemical plants, cooling lines in power plants, compressors, condensers, ink supply lines to printing presses, and for water lines to cooling towers and pumping stations where water is taken from lakes or rivers. The primary benefit of a duplex basket strainer is to provide uninterrupted downtime for maintenance and cleaning.

Keckley duplex basket strainers in sizes 3/4" – 6" have knob type covers for tool free ease in basket removal. Keckley duplex basket strainers are also designed so the handle is over the in-service chamber allowing for easy cleaning and removal of the off-duty chamber basket.

Keckley duplex basket strainers offer a compact housing and close face-to-face design for tight space requirements making them a perfect application for ship engine rooms. Keckley duplex basket strainers are offered in Ductile Iron, Bronze, Carbon Steel, and 316 Stainless Steel with an assortment of o-ring options to cover most media and temperature conditions.
