Fluid Analysis and Efficiency Improvement for Pumps

By using a fluid analysis, we optimize the shape of impeller while watching the pressure and velocity distribution carefully.
Moreover, we are realizing the coexistence of higher velocity and efficiency by making the impeller match the pump casing.

Pump Downsizing

Using 3D structural analysis, Tsurumi reduces wall thickness while fluid analysis helps maintain pump performance, enabling more compact and lightweight designs.
As a result, pump mass has been significantly reduced compared with conventional models.

Development and Design
of Liquid Ring Pumps

Liquid ring pumps draw in and compress gas using a rotating liquid ring and a crescent-shaped gas space formed inside a cylindrical casing. The impeller rotates on a shaft positioned eccentrically within the casing.
The internal flow in the pump is complicated because there are two phases: gas and liquid. In the development and design stage, we achieve optimal designs by using visualization tests to grasp the complicated internal flow and various analysis techniques. In this way, we produce highly reliable products with minimal energy loss.
