Light Liquid Sample Pumps

The Welker inFlow™ Lite is a double-acting inline sample pump designed to take quality samples of high flow condensates and natural gas liquids (NGLs) proportional to flow. Connect a solenoid, controller signal, pneumatic or hydraulic supply, and sample container to this direct-mount sample pump, and you’ve got a complete liquid sampling system.

The Welker Essentials™ Light Liquid Sampler is double-acting positive displacement pump designed to take quality samples of low volume (100–4000 bbl/d) natural gas liquid streams proportional to flow. Connect a 4-way solenoid, pneumatic supply, controller signal, and constant pressure cylinder with internal mixer to this bypass sample pump and you’ve got a complete liquid sampling system ideal for accurate composition analysis, quality control, or custody transfer.

The Welker LSS-1F is a self-purging positive displacement pump with 2” pipe spool and integrated static mixer designed to take quality samples of low flow liquid hydrocarbon streams proportional to flow or time. Connect a controller signal, pneumatic supply, and constant pressure container with internal mixer to this inline sample pump and you’ve got a complete liquid sampling system ideal for accurate water cut measurement.

The Welker inLoop™ RFP is a double-acting bypass sample pump designed to take quality samples of refined products, such as diesel, gasolines, and jet fuel. Incorporate the inLoop™ RFP into your blend header or refined product sampling system to ensure repeatable representative samples.

The Welker LSSM-1PM is a self-purging positive displacement pump designed to take quality samples proportional to flow or time. Connect a controller signal, pneumatic supply, and sample container to this probe-mounted sample pump and you’ve got a complete liquid sampling system.
