Centrifugal Sand Separators

Pumping water from wells or other sources with excessive amounts of sand, silt, or other abrasive grit particles can lead to the premature degradation of components. Rain Bird Centrifugal Sand Separators are designed to separate abrasive particles before they can enter a system, keeping equipment clean and clear of debris, which minimizes the amount of maintenance required and increases operational efficiency. These filters are designed and manufactured in the USA to exacting standards, providing many years of optimal performance.

Rain Bird centrifugal separators are designed for easy installation, minimal maintenance, and reliable operation. The separator removes sand and particles that are heavier than water (materials with a specific gravity of 2 or greater) before these particles can damage your system. Liquids and solids enter the unit, and begin traveling in a circular flow. This centrifugal action throws heavier particulates towards the filter walls and eventually downward in a spiral motion to the separation chamber. The particulates collect in the separation chamber and are purged manually from the system. The filtered water is then drawn to the separator’s vortex and through the outlet.

An optional automatic purge controller and valve can be used on all applications to automate the purge process, which eliminates the need for manual flushing. Small vertical design separators may be wall mounted or supported by the system piping.
