Precision delivery pumps of system FMI® are efficient single-piston pumps for continuous use, the sturdiness of which other pumps can hardly compete with. They are extremely versatile in use and suitable even for viscous and suspended particles-containing liquid media.
FMI®-precision delivery pumps work without valves. Their cylinders are swivelling and have involved, opposite standing medium inlet and outlet connections at the lower cylinder part. The piston working in the cylinder is mounted slewably and rotatably at the same time. A return passage is precisely ground lengthwise in the piston. During pump movement the piston rotates around its axis. At suction during the piston stroke the cylinder is filled as usual. When reaching the upper dead point, the return passage has moved to the outlet side by rotation of the piston; during the following backward motion of the piston the medium to be delivered is discharged.
By retracting the pump head by means of micrometer adjustment, the piston stroke and with it the delivery rate can precisely be altered and adjusted in a wide range.
