Centrifugal Pump Module — MOE Lab Tender Details

Centrifugal Pump Module

Allows students to study and perform tests on a centrifugal pump and optional turbines: to understand how they work and calculate their performance. The equipment should connect to a Versatile Data Acquisition System

Experiments
Centrifugal pump performance and characteristics, typically head against flow and efficiency against flow
Variation of pump performance with inlet pressure
Variation of pump performance with speed
Non-dimensional performance characteristics
Flow measurement using a Venturi
