ATTENTION
check periodically and regularly that the plungers are properly tightened, either with direct
thread connection or with clamp, in order to avoid they can get loos or out of the clamp

The use of unsuitable cleaning agents or wrong concentrations and temperatures may cause
corrosion of coatings on plungers, therefore causing a shorter packings lifetime than usual.
