Experiments With A Gear Pump

Functioning and operating behaviour of a gear pump
Sensors for temperature and pressure at inlet and outlet of the pump
Oval wheel meter as flow sensor
Closed oil circuit contains a gear pump with variable speed via frequency converter and a transparent tank
Microprocessor-based measuring technique
Transparent housing for observing the pump gears
Overflow valve for adjusting the head
Needle valve for adjusting the flow rate.
