DARcorporation offers consulting services in the development of axial/centrifugal pumps, impellers and marine/boat propellers. Our engineers can start from idea to design to analysis, tailored to your desired application and required specifications. Applications range from cooling systems in the automotive and aviation field, cavitation production in the industrial field, computer electronics.

Utilizing a rapid and powerful analytical method, DARcorporation has developed a tool to predict the performance of centrifugal pumps and marine/boat propellers. This analytical method allows us to quickly perform trade studies between different geometry parameters during the design phase. When designing a pump or marine/boat propeller, this in-house method has proven accurate in predicting trends and changes in performance based upon changing the geometry or working conditions.

Our team of computational fluid dynamics (CFD) experts are proficient in the use of Siemens Simcenter STAR-CCM+ software that is capable of analyzing the flow characteristics of existing or new pump and marine/boat propeller designs. Using CFD, we can accurately predict the hydrodynamic performance in terms of head, flow rate and efficiency, as well as pinpoint local flow issues such as recirculation.

For pump design, through changes in the casing internal volume, DARcorporation can improve the flow characteristics by decreasing flow recirculation in the outlet and allow the flow to gradually expand to a higher pressure, which can augment the pump efficiency and/or performance.

Bench testing of existing pumps and prototype marine/boat propeller designs provides detailed information on head pressure, flow rate, rpm and efficiency. The bench testing capability of DARcorporation allows for the determination of pump performance at various working conditions via calibrated flow meters and pressure sensors.
