摘要

Circulator/cleaner for fluids containing solids, and possibly, oils and fats. Esp. suitable for metal cutting machinery coolant. The vessel (2) contains a pump (1), and an impeller (6) fitted to the end of its shaft (5), projecting beyond the pump casing, and ending close to the base (2a) of the vessel. This circulates the stream (B), which is directed onto the inner wall (4). This suction inlet of the pump (1) is covered by a concave perforated plate strainer (8). The method of clearing the inner wall from deposits using the appts. described, is also claimed.
