Plastic Air-Operated Double Diaphragm (AODD) Pumps
The Almatec C-Series AODD pumps are designed as a cost-effective alternative for fluid transfer applications that do not require high specification options. All pumps are built with the distinctive and proven Almatec solid design to provide the mass needed for an oscillating pump.
The C Series features the Almatec air control system PERSWING P® which has no dead centre and requires no maintenance or lubrication. The design also includes a one-piece diaphragm, giving a long service life.
The absence of any drives, rotating parts and seal shafts eliminates internal wear and potential failure. Housing parts are tightened to each other by housing bolts tightened against a diaphragm sized ring on each side, giving an even distribution of the housing bolt force and an increase permissible bolt torque, improving pump safety.
Available in a range of materials and with ATEX conformity to 2014/34/EU
