A diaphragm pump includes a first plate, a second plate and a diaphragm having first and second side surfaces. A fluid chamber is defined by the first plate and the first side of the diaphragm, a fluid inlet fluidly connected to the fluid chamber and a fluid outlet fluidly connected to the fluid chamber. An air chamber is defined by the second plate and the second side of the diaphragm, such that the diaphragm is retained between the first plate and the second plate. A clamp moves between a first position in which the first plate is fixedly connected to the second plate and the diaphragm, and a second position in which the first plate is disconnected from the second plate and the diaphragm to permit disassembly of the first plate, the second plate and the diaphragm. |

1. A diaphragm pump comprising:
a first plate; a second plate; a diaphragm having first and second oppositely facing sides; a fluid chamber defined by the first plate and the first side of the diaphragm; a fluid inlet fluidly coupled to the fluid chamber; a fluid outlet fluidly coupled to the fluid chamber; an air chamber defined between the second plate and the second side of the diaphragm, wherein the diaphragm is retained between the first plate and the second plate; a first clamp moveable between a first position in which the first clamp fixedly couples the first plate, the second plate and the diaphragm, and a second position in which the first clamp uncouples the first plate, the second plate and the diaphragm to permit disassembly of the first plate, the second plate and the diaphragm; and wherein the diaphragm includes a circumferential flange portion trapped between the first and second plates, the flange portion having an aperture, the pump further comprising a pin extending through the aperture in the diaphragm flange portion and received in each of the first and second plates, the pin fixedly coupling the diaphragm between the first plate and the second plate. |
