High-Pressure Co-Solvent Metering Pump

High-Pressure Co-Solvent Metering Pump

Model: HPM-CS

The FLOSN HPM-CS is proposed as a compact, single-channel metering pump for adding liquid modifiers to CO₂-based processes or dosing compatible liquids into pressurized research systems. A dual-plunger drive, front-access fluid path and monitored outlet pressure are combined with a local touchscreen. Its working concept emphasizes reliable priming, manageable solvent handling and reproducible dosing at defined conditions.

FLOSN / PRODUCT FEATURES

Product Features

6 FEATURES

Single-Channel Precision Dosing

The proposed liquid path provides a defined metering channel for modifiers without implying an integrated gradient system.

Front-Accessible Prime and Purge

An accessible purge valve and waste connection simplify bubble removal and solvent changes.

Pressure-Limited Operation

Outlet pressure feedback allows the controller to stop the drive at the selected limit.

Solvent-Specific Fluid Path

Seal, head and inlet-tubing materials are selected together for the intended liquid formulation.

Organized Reservoir Handling

A retained bottle position and removable catch tray reduce loose tubing and improve service access.

Host Ratio Coordination

An external controller can coordinate this pump with a CO₂ pump; verified mixture composition needs actual-flow information.
