Diffuser range extended by PEI

Pump Engineering Inc (PEI) of the USA has expanded its diffuser line to include a total of 11 diffusers, ranging from 1 x 1 ¼ x 3 in (25 x 32 x 76 mm) up to 10 x 12 x 11 in (254 x 305 x 279 mm).

The line was expanded to optimize the energy exchange for the entire PEI product line.

Fluid velocity generated by a centrifugal impeller is efficiently converted to static pressure energy in the diffuser (the conical discharge section) of a Hydraulic TurboCharger or a centrifugal pump. When ordinary pipe reducers are used in TurboCharger or pump installations, their non-optimized, rapid area change does not efficiently convert velocity to pressure energy, resulting in flow separation and turbulence, and ultimately, pressure losses.

With PEI DEXä high-efficiency diffusers/reducers/extensions, the optimized, gradually increasing diffuser area is extended to efficiently convert velocity energy into pressure energy, resulting in several important advantages:

  • High-efficiency velocity to pressure energy recovery
  • Reduced pressure losses and energy consumption
  • Reduced flow-induced vibration
  • Reduced flow-generated noise

  • The robust cast, stainless steel, Schedule 80 design of the diffusers offers further advantages:

  • Easy and quick installation and removal
  • Groove for Victaulic type connection, weld preparation, or welded connection between diffusers
  • Suitable for a wide pipe diameter range, from 1 to 12 in (25-305 mm).

  • The diffusers are offered in stainless steel grades 316, Duplex 2205, and Super Duplex 2507 and are available for all PEI Hydraulic TurboChargers and High-Pressure Feed Pumps, as well as being applicable to any centrifugal equipment where the above benefits are desired. PEI says the diffusers are favourably priced compared with standard pipe reducers.
