Can be highly effective in reducing aeration, foaming, turbulence and noise caused by return lines
Flow rates to 300 gpm

Features

Flow diffusers are for hydraulic high-speed return lines, to slow down ﬂuids entering the reservoir. They help cure foaming problems and prevent cavitation caused by ﬂow disturbance at the pump inlet. They allow greater freedom in reservoir design and may even eliminate the need for tank baffling plates. They also reduce reservoir noise.
