Hydraulic Driven Polyurethane Perfusion Machine

Unlike pneumatic or gear-pump systems, the fully hydraulic drive generates up to 21 MPa driven pressure and sustains 10–15 MPa at the mixing head. This produces a finer, more homogeneous foam cell structure, which directly improves insulation performance in the finished product.

The main machine uses separate aluminum heaters paired with high-output heating bars, while each material hose incorporates wrapped-inside heating elements. This dual-zone approach ensures both polyol and isocyanate reach the mixing head at the correct temperature and viscosity — a critical factor for foam quality and adhesion.

A digital display controller with real-time measurement and overload protection maintains material temperatures within tight tolerances. Operators can monitor and adjust settings without interrupting production, reducing scrap from temperature drift.

At 150 Kg and just 600 × 600 × 1100 mm, the machine fits easily alongside tank assembly lines. Locking caster wheels let a single operator reposition the unit between stations, while the standard 380V/50Hz power input (customizable upon request) simplifies electrical integration.

Dedicated hydraulic pumps mounted on each material drum provide stable, pulsation-free flow at 4–8 Kg/min. This eliminates the seal-wear and crystallization issues common in vertical-pump designs, lowering maintenance frequency and downtime.
