It is a funny relationship being 6 mm bore x 5 mm hub.....but I have the small 12 Vdc geared motor @ 70 RPM & very low current draw....it also has a 4.0 mm diameter output shaft so will match the M4 pump eccentric  

I am sure that this combination will not make the    :hurle  noise of the Regner units........
