Abstract

The pump is contained in a sealed enclosure with breathe holes (3) positioned at the pump base. The pump has a static liquid presence sensor (8) which is mounted in a reverse flow tube (6) at a lower level than that of the tube output (7). The sensor is designed to detect the presence of a liquid at its level. A start/stop circuit (9) for the pump motor (4) is controlled by the sensor. The sensor may be of pressure, optical, ultrasound, temperature, capacitance, piezo-electric, or flexible membrane type.
