Prototype pump for RAS

May 4, 2016  By Quentin Dodd

In 2011, MDM of Colorado Springs, CO was awarded a Small Business Innovation Research Grant to build a prototype axial-flow pump specifically designed to improve energy cost inputs for US aquaculture businesses.

According to MDM, QSYS was developed from ground zero, examining each pump component that limits efficiency, improving the efficiency of those components, and then putting them all back together into a new concept.

The QSYS prototype allows for the flexibility of variable speed operation.

“The modularity of the design provides multiplexing in both series and parallel configurations,” notes a press release from MDM.  “It also includes ‘In-the-Pipe’ design, which makes for clean installations, protects critical moving parts from the external environment, and virtually eliminates noise, and reduces suction problems.”


Some specifications of the QSYS Prototype include the following:

• Up to 600 GPM

• Up to 10’ shutoff

• Performances at 2HP and less

• Seal-less design provides low maintenance costs

In describing the new development, Ben Ashe, Executive Vice President of MDM, said, “we believe this unique product will be the building block of a radical new system for efficient pumping.”
