Overview

A suction diffuser can be installed at the inlet of a pump, whether in a horizontal or vertical position, to help achieve a smooth inlet flow. When water flows out of an elbow or short radius pipe, it may generate rotational movement. If this rotational movement continues into the pump, it may have adverse effects. For example, the force at a point in the suction port or impeller eye may be different from the other side, causing imbalance. If the imbalance in the system is too large, seals or other components may need to be replaced too frequently. The vanes in the suction diffuser can prevent this rotation and diffuse the water into the pump. In addition, by eliminating the turbulence of the medium and protecting the impeller and seals from rapid wear, the suction diffuser can make the distance from the pipe inlet to the pump shorter. 
The suction diffuser can also filter the control circuit in the system. The internal filter screen of the suction diffuser can capture particles in the medium that are larger than the mesh, allowing the remaining liquid to continue flowing through the pipe. Since particles in the medium may damage equipment, suction diffusers are very useful in protecting the system from high maintenance costs.

Features

1. Effectively integrating piping requirements and saving installation space
2. Customized stainless steel mesh and the outer layer can be equipped with a woven filter mesh
3. There is a guide vane installed at the outlet of the diffuser which can stabilize the fluid entering the pump and extend the pump’s life
4. There is a drain outlet and support bracket at the bottom of the diffuser. Pressure gauge holes at the front and rear ends, which can be installed according to needs.
5. The blind cover is designed as a Hinge Pin energy-saving device, for the convenience of customers to perform regular maintenance and upkeep.
