Suction Diffuser
APPLICATIONS
The Keckley Style PSD mounts to the suction side of a pump in either a horizontal or vertical position. It is designed to remove any foreign matter that may be hazardous to the pump or other system components, while providing the proper flow conditions to the pump. Where space is limited, the Keckley Style PSD can be used as an elbow (in some cases a reducing elbow) with a built in strainer for easy maintenance and system performance.
CONSTRUCTION
The Keckley Style PSD Suction Diffusers are constructed from rugged cast iron castings that are machined to exacting specifications. These bodies have drilled flanges that are in accordance with ASME B16.1.
FEATURES
  • Reduces installation costs by replacing the strainer, elbow, and entry pipe on the suction side of the pump.
  • Integral straightening vanes ensure uniform flow to the suction inlet of the pump.
  • Minimal pressure drop (Oversized body & screen).
  • Perforated stainless steel screen with a 20 mesh stainless steel removable start-up sleeve to help promote a cleaner more trouble free system.
  • Bolted cover plate with O-ring seal – standard. (Knobs available upon request).
  • Cast supporting pads on the diffuser body offer easy mounting of standard I.D. support foot.
  • Tapping for inlet and outlet differential connections – Optional.
  • Drain connection with plug – standard.
