Efficiency designs the flow path. Flowing lines and smooth contours help the [MSD](https://fedco-usa.com/pumps/msd-pumps/) to be the most efficient centrifugal pump on the market.

**Maximizing Material Efficiency**

Sophisticated casting processes allow optimal usage of material; no added material if not needed and ample material where needed.

**Computational Fluid Dynamics (CFD)**

Today, CFD is widely used for fluid machine design. However, it takes hundreds of tests to fine-tune and validate the results. [MSD pump](https://fedco-usa.com/pumps/msd-pumps/) tests number in the hundreds during development.

**MSD Impeller**

**Dealing with Thrust**

Hydraulically induced axial thrust can exceed 15,000 pounds of force.

**Ring Section Pump Cross Section**

- Axial thrust increases potential for shaft bending or bowing
- Increases potential for rubs with shaft bearings and impeller wear rings

**MSD Series Pump: Patented Water Bearing**

- Axial thrust causes shaft to become straighter
- Straighter shaft reduces rubbing against shaft journal bearings
- WATER BEARING™ places the shaft in tension
