The crank arm is a core mechanical component within a diaphragm pump's drive assembly. It converts the rotational motion of the engine or motor into the reciprocating motion that drives the diaphragm back and forth, creating the suction and discharge action that moves fluid through the pump. When a crank arm is worn, cracked, or damaged, the diaphragm stroke becomes inconsistent or fails entirely, resulting in reduced flow, loss of prime, or complete pump stoppage — making timely replacement critical to keeping the pump in productive service.
