漏洩ポンプ。[Claims for Utility Model Registration] 1. A rotor is rotatably supported by a radial bearing and a thrust bearing, and a portion of liquid is formed between a high pressure part on the outer periphery of the rotating blades of the rotor and a casing surrounding the rotor. In a leak-free pump that has a structure in which liquid flows to a low-pressure part and that sucks and pumps liquid, the rotor is brought into contact with one direction of the thrust bearing, and an orifice is provided in the low-pressure part, and the orifice or A pressure detection hole is transparent to the outside of the casing from the liquid contact surface of the casing in the low pressure part near the orifice, and a pressure detection means is provided at the outer open end of the pressure detection hole. Features a leak-free pump. 2. The leak-free pump according to claim 1, wherein the leak-free pump is a magnet-driven pump. 3. The leak-free pump according to claim 1, wherein the leak-free pump is a canned motor type pump.
