Why is the outlet pressure of the vortex air pump low and the current close to the rated value?

I use it as seal air after the reducer (50 to 40) at the outlet of the vortex air pump, but the pressure of the seal air measured is only 2.5 kPa, with a current of 3.1 A. The rated current of the fan is 3.4 A, the pressure is 18 kPa, and the air flow rate is 3.7 cubic meters per minute. Why is the current relatively high even when the pressure is not high? What is the reason for this?

It’s necessary to have the pump’s manual in order to determine the pressure at the outlet and the length of the pipes

Features of vortex pumps: Power is highest when the flow rate is zero, and lowest when the valve is fully open
