PISTONS ARE A PUMPIN'
9VDC PISTON STYLE MOTOR ASSEMBLY FROM BREAST PUMP
Pistons Are A Pumpin'
It's a beauty folks. These are pretty clean take-outs from what we have been told is a breast pump assemply. They operate from 3VDC up to 12VDC, but that won't matter because we are going to include the wall adapter. (9VDC@2Amps) The steel housing measures 3.5" x 4" x 5" and inside is a gear motor, 2.5" piston style assembly and a control board. The controller has a speed control and a push button pause. The diaphram on the top of the assembly measures 2-3/4" and raises up and down about 1". It's a very soothng sound. Built in switzerland so you know is a sound unit.
