Diaphragm Pump Design: The diaphragm pump MPC 104 T consists of a pump body and a drive motor. The pump body consists of a drive shaft and four pump heads. Each pump head contains the form diaphragm and the work valves. The two pump heads are arranged opposite each other. In a three-stage (T) diaphragm pump, the two pump heads are connected in parallel, two further pumps in series. The pump heads are driven via an eccentric shaft with a connecting rod. Function: Motor, eccentric shaft and connecting rod set the form diaphragms in stroke movement. This changes the size of the space between the form diaphragms and pump head (pump chamber). Increasing the size of the pump chamber opens the inlet valve while the outlet valve is closed (intake process). Decreasing the size of the pump chamber ejects the gas through the outlet valve. The valves are actuated by the gas being pumped. A large proportion of fluid in the diaphragm pump minimizes the pumping efficiency. Materials of the Medium-affecting Pump Parts:
