Pump system design – the fundamentals

22 September, 2016

The course examines the factors that have to be considered when designing a Pump Systems, and using a combination of presentations and exercises the course takes a practical approach to what is a complex subject.

The aim is to enable individuals to enhance their knowledge and understanding of the key aspects which have to be taken into account when developing the most effective and energy efficient pump installation.

Course contents

Common types of pump systems:

• The energy equation.

• Continuity.

• Flow regimes.

• Origins of pressure losses.

• Turbulence.

• Pressure losses.

Determination of system head:

• Friction head in fittings.

• An example of the use of loss co-efficients.

• Special considerations for positive displacement pumps.

• Acceleration head.

Interaction of pump and systems:

• System curves.

• Allowing for system head estimation errors.

• Pump performance curves.

• Centrifugal pump performance characteristics.

• Pump performance with variable speed.

Pump operating limitations:

• Partial flow operation of rotodynamic pumps.

• Pump and system component inlet conditions.

• Cavitation.

• Net positive suction head.

System design

• The management of flow system design.

• Pipe work and fittings system design review.

• Sump design.

System Operation
