PSD Features & Benefits

Combined Functions – One fitting replaces a 90° ell, strainer, flow stabilizer and reducer, simplifying installation and reducing installation cost.

Space Savings – Use a PACO PSD suction diffuser whenever floor space does not permit recommended 10 pipe diameters of straight suction piping. Diffuser incorporates flow-straightening guide vanes to promote smooth, even flow profile as fluid enters pump suction thereby maximizing pump life.

Strainer – Diffuser incorporates a permanent, perforated stainless steel strainer and a disposable stainless steel, fine-mesh start-up screen for capture and removal of foreign particulates in system piping. Clean fluid, free of suspended solids helps protect pump and other system components.

Ease of Installation -- Cast iron body and cover with 125# ANSI flanges are suitable for direct mounting to suction of pump.
