ACD 2PK reciprocating pump

ACD P2K Reciprocating Pump

The vertical design eliminates gravitational loading, extending sealing ring life and provides smoother suction valve operation. Vertical installation offers less vibration, reduced noise, and compact system footprint. The vertical cold end is submerged inside a vacuum-jacketed sump, minimizing heat leak and increasing system efficiency. The sump is secured with a v-band clamp, allowing easy access to the cold end assembly.


Technology: Vertical single cylinder reciprocating pump


  • Motor positioned on the backside of the pumping skid, eliminates possible fire and explosion or hazard in case of a liquid oxygen leak
  • Replaceable crosshead wearband eliminates crosshead piston wear and reduces maintenance costs
  • Pump assembly and spare parts are interchangeable with the PD3000 pump

Typical Applications: 

  • Heavy duty cylinder filling pump
  • Medium duty cylinder filling pump
  • Unattended, automatic storage filling
