  • Page 9 <Figure A> shows the pulse wave by a eccentric cam for a general metering pump. The pulse of metering pumps generates when the eccentric cam is used to convert the power of the motor into reciprocating motions. This eccentric cam is a circular object with the eccentric amount of e, so the reciprocating velocity of the diaphragm has sinusoidal wave.
