About This Product
Running two pumps singly, in series and in parallel shows students how combined pumps change the head and flow a system can deliver. By adjusting the inlet and delivery valves and reading the gauges, they build head-flow curves for each arrangement and compare them.
Frequently Asked Questions
Are the two pumps driven separately?
Yes. Each of the two identical centrifugal pumps has its own bearing-mounted motor, so they can be driven independently.
Where does the water come from?
The pumps draw from a clear acrylic reservoir, and the water returns to it after passing the flow measurement device.
