Almatec®, a leading manufacturer of air-operated double diaphragm (AODD) pumps, has been developing and producing pump technologies that have been specifically designed for use with aggressive liquids since 1984. The construction of Almatec AODD acid proof pumps takes a number of important operational variables into account:
When configurating pump materials, Almatec application engineers help determine exactly which fluids are to be pumped in which application. The goal is to select a durable and economical acid pump solution that offers the highest level of performance and safety. Almatec pump housings are always made of polyethylene (PE), which has good chemical resistance, and polytetrafluoroethylene (PTFE), which is virtually corrosion-resistant. This makes it possible to pump almost any acid with an Almatec AODD pump.
The pump must ensure reliable tightness to minimize the risk of uncontrolled acid leakage. Almatec's solid, CNC-manufactured pump housings offer maximum safety and tightness. Significantly lower manufacturing tolerances also ensure greater running stability, in contrast to competitive injection-molded AODD pump models that can typically have a shorter service life. The choice of the self-sealing NPT thread and the elimination of two of the usual four pitch levels in AODD pumps further increases the pump's leak-tightness capability.
