Ham Baker self seal distributor column is a proven and reliable design that has been used the waste water industry for well over 50 years. Used in new build applications or used to replace old distributor installation where the original manufacture no longer exists. Self seal can be used to replace old makes of distributors like Farrer, Ames Crosta, Tomkinson, Whitehead & Poole, Simon Hartley

The Self-Seal Distributor is especially well suited to replacement of older types of distributor where modifications to the existing feed system would be both costly and time consuming. The centres are delivered to site, fully assembled to ensure down time on operational works are kept to a minimum.

The seal between the rotating and fixed columns is achieved by means of a simple nitrile ‘V’ seal running in gunmetal gland housing. The Self-Seal is also capable of taking a direct pumped flow and like the Weir Cresset can be configured to pass split flows to achieve optimum distribution at minimum and maximum flows.

The Self-Seal Distributor, similar to the Cresset Distributor, can be arranged with two arms for normal flows and the remaining two arms as overflow arms for excess flows.
