In any large installation of air-operated double-diaphragm (AODD) pumps, a relatively small portion of pumps contribute to higher than average maintenance costs, often due to misapplication. Since the majority of AODD pump applications involve no more than simple process fluid transfer, many pumps are mobile and transferred from one location to another. An operator may attribute a “good” pump installation to the pump, and not the installation. The operator may transfer the “good” pump to a new installation and soon after, the “good” pump becomes a significant maintenance problem. Worse still, the high maintenance may become routine, resulting in substantial costs, in relation to the pump. Since most AODD pump applications are either simple transfer or filter press feed, following a few necessary steps can avoid costly mistakes.
The pump may not be a bad actor.
