How to test-run a gear oil pump

The entire pump is installed vertically, with the pump body inside the oil tank and the motor outside. Question 1: Since the couplings can’t be seen, how can the pump be turned manually? 2: For single-unit testing, since the pump and the motor are inseparable, can only a combined testing be carried out? 3: The pump in the oil filler is a plunger pump, right? So how does one rotate it manually and conduct a standalone test run?
1. The flywheel of the disc compressor. 2. Only one unit can be tested at a time. 3. It is a piston pump; when testing, move the heat sink on the motor, and the oil injection line can be removed separately during testing
Stationary pumps generally do not require shaft rotation; they are equipped with self-starting interlocks. Shaft rotation is unsafe, and pumps that are installed vertically are less likely to experience shaft bending issues
