Low-pressure series
Low-pressure PU foaming machine
Two-component mechanical mixing, 100–200 g/s standard output and a needle-valve gun head with vacuum suction.
The standard machine meters polyol (POL) and isocyanate (ISO) into a mechanically agitated mixing head. Jacketed tanks circulate hot or cold water to condition the materials before metering. A needle-valve head uses vacuum suction to reduce residue after dispensing.
For filled or higher-viscosity formulations, share the material data, mixing ratio and shot weight for review. The required pump sizes and temperature settings depend on your materials and process.

Material handling and controls
- Material conditioning — Jacketed tanks have pneumatic stirrers, level sensors, level tubes and temperature sensors.
- Metering seals — The gear pumps use a four-layer seal with a spring-energized seal, spacer, oil seal and grease.
- Recipe control — Store settings for repeat jobs and adjust metering through the variable-frequency drives.

How does the small machine differ from the standard machine?
The small two-component machine has a 50–80 g/s output range and two 20 L tanks. The standard configuration has a 100–200 g/s range and two 250 L tanks.
Can I use calcium carbonate in the polyol?
The published limit for suitable formulations is 25% in POL. Share the viscosity, filler content and target hardness during equipment selection.
Which utilities should I check before ordering?
Confirm site power, pneumatic supply and temperature-control requirements for the proposed configuration. Include available clearance around the machine and swing arm.
