LPG loading arms

Liquip offers a custom designed low profile loading arm for LPG (Liquified petroleum gas).

The highly advanced 3" Liquip LPG loading arm is designed to provide efficient loading with an emphasis on occupational healthy and safety. 

Unique to Liquip is fitment of a spherical knuckle joint behind the connector to the tanker which removes all stress from the system during connection & also as the tanker suspension settles during the loading process.


Features & Benefits
  • High pressure swivels enable loading up to 120m3/hr.
  • The balance mechanism has a cantilever action to ensure the loading coupler remains horizontal in any position to accomodate different adaptor heights.
  • LPG arms fold away for safe compact storage.
  • Electronic interlocks ensure the arm is disconnected and stowed.
  • Replaces the need for heavy and hard to handle liquid loading hoses.
  • Remote draining valve to empty final pipe section of liquid before disconnection.
  • Parallelogram linkage to hold outboard pipe section horizontal at all times.
