HX12 Series Piston Pump FAQ
1. What are HX12 series axial piston pumps?
The HX12 is a high-precision, swashplate-style axial piston pump designed as a core metering component for Hennecke’s polyurethane processing systems. Featuring a robust cast iron housing and optimized self-cooling design, it is specifically engineered for continuous high-pressure metering of polyols, isocyanates, and other reactive fluids.
2. What makes the HX12 different from standard gear pumps?
The HX12 is built for precision metering and high-viscosity fluid handling where gear pumps may underperform:
-
Superior Volumetric Efficiency: Its precision piston design maintains consistent flow across varying pressures and fluid viscosities, eliminating the slip common in gear pumps.
-
High-Pressure Capability: Rated for continuous operation up to 240 bar, the HX12 handles the high pressures required for fine-bubble foam and high-density elastomer production.
-
Low Dead-Volume Construction: Reduced internal chamber volumes minimize raw material waste during flushing, a critical advantage for expensive or reactive PU components.
3. What is the working pressure range of HX12 pumps?
The HX12 is a high-pressure metering specialist, with performance tailored for industrial PU applications:
-
Continuous Operating Pressure: Up to 240 bar.
-
Safety/Maximum Pressure: 320 bar.
-
Permissible Pre-Pressure: Up to 16 bar in open-circuit systems.
This robust pressure rating ensures stable, consistent flow even in demanding continuous production environments.
4. Can HX12 pumps replace other brands?
Yes, the HX12 is a high-quality alternative to other premium metering pumps. It is often used as a replacement or upgrade for:
-
Grundfos DME Series (PU metering applications).
-
Bran+Luebbe NOVADOS Pumps.
-
Lewa Ecoflow Series (low-to-medium flow industrial dosing).
To ensure a successful swap, verify the displacement, shaft interface, and fluid compatibility to match your existing system.
5. What hydraulic fluid/PU components are suitable for HX12 piston pumps?
To protect the precision pistons, swashplate, and bearings, the following is recommended:
-
Fluid Type: Polyols, isocyanates, and compatible industrial fluids. For standard operation, use clean, well-maintained fluids.
-
Viscosity Range: Up to 8,000 mPas, supporting both low-viscosity isocyanates and high-viscosity polyols.
-
Filtration: Cleanliness is vital for piston and bearing protection. A minimum filtration level of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging critical surfaces.
6. What is the typical speed range of HX12 pumps?
The HX12 is optimized for controlled metering speeds in continuous production:
-
Standard Operating Speed: 300–1800 rpm.
-
Nominal Displacement: 12 cm³/rev.
The pump’s self-cooling design ensures stable operation even at continuous high speeds, preventing thermal buildup and process drift.

FAQ
1.How does the variable displacement work?
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
