Claims

[Claims for Utility Model Registration] (1) A diaphragm pump 10 in which the pump chamber 24 is partitioned by a diaphragm body 18, and the volume is increased or decreased by the deflection movement of the diaphragm body 18.
, a layered liquid detector 58 that detects the presence of liquid by contact with the liquid and is distributed over the entire diaphragm body 18, and a layered liquid detector 58 that detects the presence of liquid by contact with the liquid and that each breakage location has different failure characteristics in response to a load on the diaphragm body 18. diaphragms 60 respectively covering both sides of the layered liquid detector 58;
, 62. A diaphragm body for a diaphragm pump, comprising: (2) A diaphragm body 18 according to claim 1, and a pump control means 70 that stops driving the diaphragm pump 10 when the layered liquid detector 58 of the diaphragm body 18 detects liquid. A drive control device for diaphragm pumps.
