SW Series Nano Dispersion Homogenizer
The SW Series applies high-pressure homogenization for nanomaterial dispersion, pharmaceutical emulsification, and cell disruption, from lab scale at 40 L/h and 150 MPa to production scale at 1,500 L/h and 100 MPa. Stellite-alloy, zirconia ceramic, and diamond valve options with zirconia ceramic plungers maintain consistent performance across carbon nanotubes, graphene, liposomes, and fat emulsions. A modular chamber design on both configurations minimizes product retention and reduces cleaning downtime.
Specifications
| Model | Scale | Max Pressure (MPa) | Flow Rate (L/h) | Motor Power (kW) |
|---|---|---|---|---|
| SW1006 | Lab | 150 | 40 | 3 |
| SW3055 | Production | 100 | 1,500 | 55 |
Operating Principle
SW Series — Plunger and high-pressure valve assembly
===
A reciprocating plunger builds pressure in the homogenizing chamber, forcing the product through a precision high-pressure valve at up to 150 MPa (SW1006) or 100 MPa (SW3055). As product passes through the valve gap, simultaneous shear, cavitation, and impact forces reduce particles and agglomerates to nanoscale. The modular chamber design ensures minimal internal product retention; check valves control inlet and outlet flow at each stroke.
Key Features
- SW1006 valve options — Stellite alloy, zirconia ceramic, or diamond; rated for continuous duty at up to 150 MPa; both valve faces interchangeable to extend service life
- SW3055 valve — R-type zirconia ceramic construction; pneumatic pressure control with solenoid valve and pressure stabilizer for consistent production-scale operation
- Zirconia ceramic plungers on both models, fitted with UPE/PEEK composite seals for higher mechanical strength and wear resistance than PTFE alternatives
- SW1006 homogenizing chamber — super-high hardness special alloy forging, solution-treated and ultrasonically flaw-detected; US GEMS sanitary diaphragm gauge rated 0–2,000 bar at ±1 bar accuracy
- SW3055 homogenizing chamber — SAF2507 duplex stainless steel; 3-plunger assembly with integrated plunger cooling water for sustained high-throughput operation
- Siemens motor and drives on both models; 10-inch touchscreen HMI with VFD speed control, alarm outputs, process timer, and password-protected access
Experiment Results
Carbon Nanotube Dispersion
The SW3055 was evaluated on carbon nanotube dispersion uniformity against two leading high-pressure homogenizers. The SW3055 result was rated Excellent — the highest performance tier — with the fewest agglomerated filament clusters visible under microscopy. Fewer black filament clusters in the image indicate better dispersion quality.

Graphene Particle Size Reduction
A customer required graphene ground to below 5 µm. The SW3055 ran at 30 MPa for one hour, then pressure was increased to 60 MPa for final discharge. Output particle size measured approximately 4 µm, meeting the customer specification.
