4 . Pum p Const ruc t ion 4.1 Components (1) Pump drive: Moves the diaphragm in a back-and-forth motion. (2) Pump head: Performs suction and discharge using the back-and-forth motion of the diaphragm. (3) Suction port: Connects the suction hose. (4) Discharge port: Connects the discharge hose. -
Page 9: Construction
4 . Pum p Const ruc t ion 4.2 Construction Two bearings are fastened eccentrically to the camshaft that is directly connected to the motor axle. The backup is constantly pressed against the bearings through spring resistance. When the crankshaft turns, it pushes out the backup through the eccentric movement of the bearings. Then the diaphragm at the end repeats a suction/discharge motion by the back-and-forth motion of the crosshead. -
