1. Unpacking and Inspection
The Iwaki EH series electromagnetic pump is a
diaphragm metering pump of the 'linear
electromagnetic drive system', which means
electromagnetic force drives the diaphragm directly.
It consists of a pump unit, a drive unit and a control
unit. Reciprocating movement is caused by the
electromagnetic force produced by the pulse current
sent from the control unit, and the force of a spring.
The reciprocating movement is transmitted to the
diaphragm directly connected to a plunger, to
change the capacity of the pump chamber. The
changed capacity and the functioning of the valves
in the pump unit drive the pump.
