Automatic Flow Control

The desired flow rate is preset by means of a screw adjustment on the case and then maintained constant within a tolerance of ±5% by means of an electronic control circuit. When pressure drop across the filter increases, this system automatically senses the rising demand by the motor and adjusts its voltage to compensate.

The pump is housed in a lightweight plastic case and includes a belt clip.
