Series And Parallel Pumps Test Set :
Bench-top test set that allows students to investigate the operation and performance of a single centrifugal pump and two centrifugal pumps in both series and parallel. 

• Self-contained, compact, bench-top, easy-to-use test set for a range of experiments and demonstrations 
• Easily configurable system to enable pumps to be tested individually, in series and in parallel, with a manually adjustable water flow rate 
• Long-life, robust valves with large handles allow students to change the water circuit In seconds, ready for the next experiment.
• Includes pressure gauges to measure intake and delivery pressures 
• Discharge flow measurement 

Comprehensive demonstration and investigation into a centrifugal pump including: 

• Characteristics of a single centrifugal pump 
• Comparison of two identical centrifugal pumps 
• Investigations of total head and flow rate in series and parallel pumps 
• Suction tests on a single pump 
• Demonstration of cavitation
