Come home. Book your ticket for the Turbo & Pump Symposia

The 43rd Turbomachinery and 30th Pump Symposia are quickly approaching. The 3-day event will begin on September 22nd in Houston, Texas at the George R. Brown Convention Center. The Symposia are organized in order to promote professional development, technology transfer, peer networking and information exchange among industry professionals. The event serves as a premier training and networking opportunity for professionals in both the turbomachinery and pump industries.

In ancient Greece, a symposium was a drinking party. Hosted by Socrates and philosophers alike, they were used to celebrate and discuss matters most vital to the universe. The “symposium” was a source of pride for the ancient aristocrats. Continue reading “Come home. Book your ticket for the Turbo & Pump Symposia”

Axial and Mixed Pump Theory

Axial Pump
Axial Pump

Unlike the centrifugal pump, the performance in axial machines is a function of the action of the blade profiles. Because of this, the main approach in design of axial pumps is focused on blade performance.

Impeller blades of axial flow pumps have a double curvature form at the inlet and at the outlet due to the change in diameter from hub to periphery. Absolute flow before and after the impeller and relative flow along the impeller passage are axisymmetric and potential. There is no radial mixing. Under this condition, each streamline is parallel to the axis of the pump. Fluid passes parallel to the pump axis i.e., along the streamline. Continue reading “Axial and Mixed Pump Theory”

Criteria for Selecting Pumps – Specific Speed

We had a great week last week with our Steam and Gas Turbine Design workshop and we thank all of our participants who joined us in Boston and Zug, Switzerland! But like any rotating turbomachinery company, we’re rotating right along into another topic, pumps.

As with any turbomachine, when you’re in the process of selection, you should take into account a few factors depending on the application.

The specific speed should be the first parameter to take into account when designing and installing a new pump. Continue reading “Criteria for Selecting Pumps – Specific Speed”
