Almatec ADX Series Stainless Steel AODD Pump

ADX Series Stainless Steel Metal AODD Pump

Transferring corrosive chemicals and high-temperature fluids using underspecified equipment poses a serious risk. Seal failures, diaphragm breaches and material degradation can lead to unplanned downtime, costly repairs and safety hazards for personnel and surrounding infrastructure.

The Almatec® ADX Series Air-Operated Double-Diaphragm (AODD) Pump is constructed from precision-cast stainless steel and engineered to perform under aggressive fluid transfer conditions across a wide range of industrial applications. For facilities with strict safety requirements, the ADX Series also supports optional monitoring systems and is available in ATEX-compliant configurations.

Features at a Glance

  • Robust construction with the mass and proven internals required for reliable oscillating pump performance
  • Wetted housing parts constructed from stainless-steel precision casting 1.4408 (SS316)
  • Non-wetted air area available in three plastic materials (polyamide, conductive polyamide and conductive polyethylene) to meet various temperature requirements
  • Available in two ATEX-compliant variations per directive 2014/34/EU, rated for operating temperatures up to 80°C (176°F) or 120°C (248°F)
  • Free-rotating suction and discharge ports
  • Valve stops engineered for simplified maintenance, easier cleaning and increased safety
  • DIN and ANSI flange options, welded in a compact design in a defined position
  • Additional connection options, including sanitary threads, Tri-Clamp and open butt welding
  • Compatible with monitoring systems such as stroke counting, diaphragm sensor and barrier chamber system
  • Enhanced sealing and bi-directional diaphragm clamping for increased safety
  • Available in ADX20 (3/4") and ADX25 (1") sizes; both sizes are identical in construction but come equipped with different suction and discharge ports
