Project Description

Suction Diffuser

There are many different industries use suction diffusers. For example, the process industry, metals and mining, power industry, water and waste, chemical industry, pulp and paper, oil and gas industries all use suction diffusers. Also suction diffusers are installed on the inlet of a pump to help a smooth in-let flow. Additionally they remove objects from damaging the pump. Moreover, suction diffusers provide ideal flow conditions for the pump. Thus suctions diffusers reduce the amount of pipe that would be needed to achieve a steady flow.

Pump Suction Diffuser

Additionally pump suction diffusers shall be attached to the side of the pump. As well as made to code. In addition, the pump suction diffuser has a strainer. Therefore, it can stop unwanted material from entering the pump. Furthermore, pump suction diffusers give the right state of flow conditions to the pipe. Also extra features for a suction diffuser include a throwaway stainless steel start-up screen. The piping system uses this screen for the capture and removal of unwanted items. Also we supply a movable support for mounting.

Strainers and Suction diffusers are similar. Suction diffusers are a type of strainer. Additionally, in smaller areas that are harder to access, the pump suction diffuser is attached to the pumping-equipment inlets. Thus saving space and lowering cost. They eliminate the need for an equivalent length of up to ten pipe diameters of straight run on the suction side of the pump.

The Strainer Suction Diffuser mount directly to the suction side of the pump in either a horizontal or vertical position. Also they can be manufactured in accordance with ASME B31.1, ASME B31.3 and/or ASME Section VIII, Div. I and are available with Raised Face, Flat Face or Buttwelded connections.

Particles and debris from the flow can be removed by both suction diffusers and strainers. They both can have screens that reduce risk of damage to equipment such as pumps, and compressors. Different types of strainers are fabricated duplex strainer, Y strainers, temporary strainers, T strainers, and basket strainers. When you don’t use a suction diffuser for a pump, sometimes you will use a bellow pump connector or braided flexible metal connector.

A commercial suction diffuser and an industrial suction diffuser can be made as a casting, or can be custom fabricated.

What is the suction diffuser’s purpose?

Suction diffusers are a combination elbow, reducer, and strainer. Therefore, this combination reduces labor and costs. By looking at it you can see that it is an elbow and a reducer. The suction side should match the pump size. Moreover, the inlet side can be the same or a larger size. Furthermore, the suction diffuser diffuses the water into the pump. It is a flow straightening device that provides the most flow efficiency at the suction inlet of the pump.

Fabricated Suction Diffusers

Firstly, fabricated suction diffusers can take pressures up to 740 psig. and temperatures up to 800 degrees Fahrenheit. Furthermore, we supply standard and custom designs. As well as make our fabricated suction diffuser with any inlet size connection. Additionally we supply one, three, or five diameters of flow straightening. Also our industrial suction diffusers comes with pads for mounting, and a drain connection with plug. Data packages and MTR available. We can supply any material needed for an industrial suction diffuser, or a commercial suction diffuser. Mostly used is carbon steel or stainless steel. Feel free to contact us for any questions.
