As a leading manufacturer of rotary distributors, Amwell offers proven quality and dependability, in both “reaction driven” and “motor driven” designs. Choose from two, three, or four arm distributors in diameters up to 150 ft. Where flow rate and hydraulic pressure is insufficient to drive the arms. Amwell offers motorized center columns to handle any need. A large lower guide bearing is provided for stability and is protected by multiple spring loaded mechanical seals which are capable of withstanding high hydraulic surges.

Exclusive Amwell Multiflo brass nozzles maintain an even flow and dispersion rate throughout the entire length of each distribution arm. These free draining nozzles made from non-corrosive brass are available in 3/4" and 1-1/4” diameter sizes. Each size nozzle is available with a series of weighted self-adjusting spreader covers to provide excellent flow distribution on the trickling filter media. This nozzle design has proven to be very effective over a wide range of flows and head conditions.
